ignition control module ? 88 taurus 3.0L v6

hi .. the car is weird .. some days it goes good drives nice feels fine, other days it backfires and feels like it's slipping..

most of the time it only backfires when driving

does anyone know the screw size to get to the ignition control module to get it tested? i tried and tried but nothing seems to fit

also, the plugs/wires/rotor/cap/temp sensor/fuel pump/tps/rack/pspump have been replaced along the way .. the car's pretty old. eh.

thanks, christopher

You best bet is start with a fuel filter replacement if its been a while........How long has it been on the plugs and wires? I think the module is held on with 7/32 or 1/4 socket, cant remember off hand. There is a special one for it available very cheap at auto parts stores but you can also ground down the outside of a regular one to get it to fit inside the little holes.

i forgot to mention that i just replaced the fuel filter like last week cuz that was recommended to me about it backfiring

it seems really they have tried everything to get it to stop .. i don't know really .. maybe the fuel pump got put in incorrectly? .. the plugs/wires are fairly new actually the car was sitting for a year or so so they are very new really and the car was only driven maybe 2 miles per day

it had its transmission replaced about 3 yrs ago, which leads me to wonder, why are these tauruses so prone to transmission failure? a friend was telling me hers on her 99 went out, and she just let the repair shop keep the car .. i understand it going at 100K mi, but 40K?!

put it on the computer it says 02 lean and TPS something, but the TPS might have been the battery cables being loose ..

im not really qualified to diagnose, but when it goes to the mechanic there is absolutely nothing wrong, it shifts perfect, starts on first crank, its just a fine and dandy little car

Check your plug wires. Check your vacuum hoses for cracks or leaks.

Buy the special TFI removal tool for 6 to 8 dollars or so. Its a very thin wall socket to get into the TFI holes. If you change the modules, be sure to put the heat sink compound on the back of it before you put it on.

it cant be the timing chain, right?

Timing can cause a backfire, but most likely it is not the chain. If it were, it would do it more consistantly than you discribe. Your problem sounds like it is probably fuel related. Since you already tryed a fuel filter and pump recently?, try running a can of fuel injector cleaner through it.....

fuel pump is now dead .. have to really check to see now what is wrong with it umm put on a pressure tester, it reads 0, so ...

============================= Sounds like its time to check for power at/near the pump and go from there. Keep in mind the computer will only send power to the pump for a few seconds when you turn the key on or if you are cranking the engine.

i thought after cranking, it would still hold pressure for a while?

either way, the car is dead, now to find out why

hee hee

(if only i had enough time off work to really look at this ..) :-D

========= yes...but I was talking about 12volts of power to the pump
