99066F: Is this GM recall real??

Hope someone out there can tell me something about this situation - I'm getting no help from GM. Sorry for the long post, but the details may be important.
Here's the story. I've got a '96 1500K, 5 speed, 4.3l V6. For a few years now, it'll run rough at mid rpms (1500-2500), missing badly. At one point, I'd just replace dist. cap and rotor, and that would seem to help for a while. For the past 6 months, it's been worse, also causing rough idle. The missing at mid rpms almost never goes away - sometimes it would before, after the engine was warm. In the past few thousand miles, I've replaced cap, rotor, coil, wires and plugs. Did the TSB on the coil wire. Nada. Still misses, SES light is on and codes say "random misfires", and do not single out any cylinders. BTW, engine purrs under heavy acceleration, never misses. Generally also smooth at idle.
Had it in a shop - one I trust. They thought the fuel pump was bad due to low pressure, tried a new one but still couldn't get much above 52 psi - too low for consistent operation of the injectors. Bad pressure regulator? Maybe. He did a lot of research online with his tech. service and found that, per the service, GM had issued a nationwide recall in 2003 on the 4.3, 5.0 and 5.7 l engines, 1995-2002, for defects in the injector assemblies. The symptoms described were just like I've experienced. The GM recall number was listed as 99066F. He called one dealer (jerks) who said there is no such recall. Another dealer said they heard of it, but said we'd have to call GM direct and find out what they'd do for us.
I called GM and got a major run-around form the customer service rep, who insisted there was no such recall, or "policy" as GM calls it. Then she found one (99066G), but only for Calif. trucks. Very evasive, and tried to deflect my questions. I had the mechanic try. He got the same run-around, but get this: first, they tell him that there is no recall, then they say that even if there were, it would not apply to my VIN. But, they sadi, I should check with a GM dealer because they might be able to "help me out" with the problem. WHAT KIND OF BS IS THIS?? I am convinced that GM is aware of the problem, but is doing everything possible to keep a very tight lid on it.
I am going to the one (helpful) dealer to have them check it out. In the meantime, does anyone have any ideas as to 1- know if this recall does exist, and 2- getting GM to react in a responsible, customer-friendly way, if it does? I'm not anxious to spend $800-$1000 for the fix if GM should be picking up the tab.
Thanks a lot

I just searched the GM site (I'm a GM tech and have access to the online site) and the only one is the 99066G special policy. I've heard about this one, and it only applies to GM trucks registered in California. The reason for this is the laws in California. Apparently, they have forced GM to offer the extended warranty in that state. So if your truck is not registered in California, you are out of luck. There is no mention of VIN breakpoints in the special policy that I can see.

What she may have been trying to tell you is that if you had a good relationship with a dealership, they might be able to work out some sort of "goodwill" policy with you. We do it all the time at our dealership. It can range from "you don't pay a cent" to "you pay 1/3, GM pays 1/3, and the dealer pays 1/3". Of course, it usually hinges on how good of a relationship you have with the dealer. Which in your case, might be iffy, unless you have more info available as to how much work you get done at the dealership.

I suspect you will be paying for most of the tab, if not all. Maybe you will get lucky. I'll include the body of the special policy below so that you can read through it and at least be familiar with it. By the way, the dealership that told you that there is "no such policy" as the 99066F was correct. What GM does is continually update the policies. As they do, each succesive update is "lettered", so the first update could have been 99066A and then have gone on up to "G". The important thing is to look for the 99066 policy, no matter what letter comes after it.

Special Policy Adjustment-Sequential Central Port Fuel Injection (SCPI) Failures in California Only (YF5 Emission Equipped) #99066G - (Nov 5, 2003) 99066G -- Special Policy Adjustment -- Sequential Central Port Fuel Injection (SCPI) Failures in California Only (YF5 Emission Equipped) Certain 1996, 1997, 1998, 1999, 2000, 2001, 2002 S/T, M/L, C/K, G, P, W4/NPR Trucks and 2003 NPR Trucks
Equipped with 4.3L (RPO L35-VIN Code W or RPO LF6-VIN Code X), 5.0L (RPO L30-VIN Code M) or 5.7L (RPO L31-VIN Code R) Engine and California Emission Equipped (RPO YF5)
This bulletin is being revised to emphasize to Dealers the important of replacing the engine SCPI fuel assembly with the new MFI fuel assembly if the vehicle has already received an injector cleaning. Please discard Special Policy Bulletin Number 99066F, dated March, 2003.
Condition Some owners of 1996, 1997, 1998, 1999, 2000, 2001 and 2002 model year S/T, M/L, C/K, G, P and W4/NPR trucks and 2003 NPR trucks that are registered in California, equipped with 4.3L (RPO L35 and VIN Code W or RPO LF6 and VIN Code X), 5.0L (RPO L30 and VIN Code M) or 5.7L (RPO L31 and VIN Code R) engine, and California emissions (RPO YF5), may experience a Service Engine Soon light, misfire, rough idle or hard start due to a deposit build up on the Sequential Central Port Injector (SCPI) poppet valve(s). The deposit build up may cause injector poppets to stick closed. Fuels used in California have been found to interact with the SCPI system to cause the deposits.
Special Policy Adjustment This special policy covers the SCPI failure condition described above for a period of ten (10) years or 200,000 miles, whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
The repairs will be made at no charge to the owner. This special policy applies ONLY to repairs requiring SCPI system servicing and/or injector cleaning and/or MFI assembly replacement of the SCPI system. The customer should not be charged for performing a system check when it is determined that the SCPI system is not the cause of a customer complaint (labor operation T5532 is provided to submit claims for such system checks). Any additional necessary diagnosis and repairs that are not related to the SCPI condition are NOT covered by this special policy. The customer should be informed that any further service that is not covered by new vehicle warranty will not be covered by this policy.
Vehicles Involved Involved are certain 1996, 1997, 1998, 1999, 2000, 2001, 2002 S/T, M/L, C/K, G, P, W4/NPR and 2003 NPR model vehicles registered in California, equipped with 4.3L engine (RPO L35-VIN Code W or RPO LF6-VIN Code X), 5.0L engine (RPO L30-VIN Code M) or 5.7L engine (RPO L31-VIN Code R) and California emissions (RPO YF5). This Special Policy covers all vehicles within these model years, with these engine and emission RPOs.
Service Procedure System Check
Use strategy-based diagnoses listed in the front of the Driveability and Emissions section of the Service Manual. If the SCPI system is operating properly, inform the customer that the vehicle does not have the condition listed in the owner letter. If poor driveability conditions persist, inform the customer that any further diagnosis and repairs will be at their expense if the vehicle is outside the parameters of the New Vehicle Warranty.
SCPI Injector Cleaning Procedure
If diagnosis leads to sticking poppet nozzles, first check GMVIS to determine if the vehicle had a previous claim for injector cleaning under labor claims J5645, T5534 or T5540. If any of these three repair claims are listed, do not clean the injectors, but rather replace the engine SCPI fuel assembly with the MFI fuel assembly. If none of these three repair claims is listed, use the service procedure from Service Bulletin 00-06-04-003B to clean the SCPI poppet nozzles. Please note that the service bulletin term for SCPI is Central Sequential Fuel Injection (CSFI), but is referring to the same fuel system assembly.
SCPI Fuel Tank Fill Pipe Assembly for 1997-99 M/L Van and 1999-some 2000 C/K Truck; with 4.3L, 5.0L, 5.7L engines and built prior to listed VIN/Production dates on Service Bulletin 00-06-04-018
If diagnosis leads to sticking poppet nozzles on these models, use the service procedure from Service Bulletin 00-06-04-018 to replace the fuel tank fill pipe assembly, if this procedure has not been performed previously. Previous service procedure can be verified by checking GMVIS for Labor Operation L1065 on M/L trucks with replacement part number 15050573; or Labor Operation L1065 on C/K trucks with replacement part numbers 15747585 or 15747588.
Correction
If, AFTER cleaning the SCPI poppet nozzles, the normal service manual diagnosis still indicates that the SCPI is the cause of the customer complaint, or if the injectors have previously been cleaned and the vehicle has again experienced sticking poppet nozzles, refer to Service Bulletin 00-06-04-003B and replace the SCPI fuel assembly with the MFI fuel assembly. Please note that the service bulletin term for SCPI is Central Sequential Fuel Injection (CSFI), but is referring to the same fuel system assembly.
Customer Reimbursement Customer requests for reimbursement are for any previously paid repairs to, or replacement of, the Sequential Central Port Fuel Injection (SCPI) system. Repairs must have occurred within 10 years of the date the vehicle was originally placed in service, or 200,000 miles, whichever occurs first. The requests are to be submitted within two (2) years of the date on which the repair was paid or within two (2) years of the date of this Special Policy Bulletin, whichever is greater.
When a customer requests reimbursement, they must provide the following:
a.. Proof of ownership at the time of the repair b.. Original paid receipt confirming the amount of the unreimbursed repair expense(s) (including Service Contract deductible), a description of the repair, the date repaired, and the person or entity performing the repair Customers from the State of California must submit requests for reimbursement directly to (divisions) per instructions in the owner letter.
If the work was done by someone other than a GM dealership, the amount of reimbursement will generally be limited to the amount that the repair would have cost GM to have it completed by a GM dealership.

Yesterday, my 04 CPI T15 Jimmy stalled three times, each time when I stopped for a light. It seemed to run fine other than that. The first stall was difficult to restart, and required full throttle, so I suspect it was flooded. Any suggestion where to look first? I had no check engine light. Nothing on the CPI, nor the EGR, has ever been replaced. It starts and runs fine, cold. Dan

If you are outside of California the dealer would probably not know of it. I believe the part numbers are listed on the TSB to switch to the new injector setup. You can order it online for just over $200 plus S&H. The injector assembly includes the fuel pressure regulator
