I could use some help here......

I hope someone on the list can help with a problem I'm having w/my son's car. I've been driving it since he went into the service last May, I have had a few repairs, exhaust system, clutch cable, oil change, tune-up etc... I went out this morning to start the car and it turned over, almost started a couple of times but then it just tired. I've had this happen once or twice before but it always eventually started.... before. We've checked the plugs clean, gapped correctly and getting juice, but there was no fuel getting to the injectors. Checked the filter and thats not the problem. Our next step is the pressure regulator. Is there anything we forgot to check before we start on the regulator? And yes we do have gas.........I checked after I did the plugs.

Thanks Liz

You forgot to tell us the year, make and model. ALL CARS ARE NOT THE SAME!!

Actually, I would check fuel pump before going to pressure regulator. And this is on any fuel injected car.

Sure, no matter what kind of car it is (and I suspect GM) the fuel pump has to be operational and the fuel lines have to be clear. You have already dealt with the filter.

Check those items first. Ive seen GM fuel pumps go out more often than problems with the fuel pressure regulator.

Lot of unanswered questions here.:shakehead :lol: Is it turning over normal. Is it getting good hot spark to all 8 plugs? What is the tune up history? Mileage on Plugs and what brand? Got good fuel pressure? Tips on getting a good answer to your questions. People trying to answer your question do not have a crystal ball. So give them all of the info you have like year make and model and engine and transmission and mileage. Also cars engine and transmission service history or any recent repairs or problems. Also a description of your problem and what it is doing or not doing. If you have codes give up the code no. And remember a code does not say replace the part but only points to the problem that you have to check out. So to better help you give up all of the info you have on it. MT

What make and model is it?

If you have spark and you have fuel and you have air, the engine will run. If one of those are missing, it will not.

Stick a pressure gauge on the fuel rail. You'll see if there is correct fuel pressure or not. If the pressure is in the ballpark, the fuel injectors are not opening. If the pressure is way too high or way too low, you have an issue with the regulator, pump, or filter in the fuel line. Pull the regulator return line and see if it's dumping all the fuel out. If it is, the regulator is an issue. If it's not, check the voltage at the fuel pump and make sure the fuel pump is running.

But do you have fuel *pressure*?

When you get in and turn the key to "run" (not "start"), do you hear the fuel pump in the tank buzz for a second?

Did you make sure the "inertia switch" in the trunk hasn't been tripped, cutting off power to the pump?

When you use a piece of wire to ground the tan/light-green wire at the EEC test plug under the hood, does the pump run as long as the key is "on"?

Do you get a strong blast of fuel from the test port on the fuel rail (looks like a tire valve in the middle of the chrome fuel piping... watch your eyes)?

It sounds to me like you are describing a battery with low power. If it stopped turning it over, then there wasn't likely enough power to turn on the vehicle's computer systems.

I would recommend you try a boost. if that works, then a battery cable end clean is in order with a battery test.

Liz, Cinsidering the spread of opinions, it would be very interesting to learn what the problem really was when you have it fixed. Please, post back when you can. Thanks :)

Elementary, my dear Lizma... I had assumed that you had a fully charged battery and ran it down trying to start it. Mike is right. No tickee, no washee
