MY VETTE WONT START
Well this is what happens, I have been having the car sputter and jerks. We have no codes coming up on the car. We replaced O2 sensors, spark plugs, fuel treatment, injector treatment and fuel filter. Now Monday the car died on me and I drove it home, and now the car starts and dies right away. It would seem to have something to due with the fuel. Someone told me it could be the fuel pump. Because there might be a bad wires or something. It was picking up gas but not sending it right, causing the car to jump and sputter. Does anyone else know what could cause this? Thank you

It probably is the fuel pump. Open the gas cap and have somebody turn the key on while you listen by the fuel filler area. You should hear the fuel pump come on for a couple seconds. Let me know what happens and we'll go from there......

what did you clean the injectors with. i'm not sure about the 85 but the later models have fuel cooled coils. any cleaner that eats lacquar will do damage to these injectors.

The fuel Pump comes on but the pressure seems fine, but it was just a problem while the car was running now it does not run at all. What else could it be? Any other info would help.

You need to hook up a fuel pressure guage to the schrader valve to monitor the FP to see if it is actually a pressure problem. Otherwise you're just guessing. If it is FP then you can pinch off lines to isolate the problem. If not, you can go in another direction.

Re: MY VETTE WONT START (Lacrosse_21)
As I am going through my car I have learned to look for simple things
1) The only fuel thing you can do without checking the fuel pressure is to unplug the fuse for fuel pump. If it starts, it's too rich...if it doesn't, go look somewhere else.
2) check ignition, these l98 tend to burn up plug wires (and altenators), check em'
3) check air, is your IAC plugged in? is your MAF/MAP plugged in? Try starting the car while the TPS is unplugged while adding "throttle". The lack of TPS signal won't let the computer know that you have it floored while cranking an thus not adding fuel. If it starts, you've got to much fuel.
in any case you need to have the right tools, fuel pressure gauge, volt/ohm meter, and others.

You should check the pressure at the rail if you think it is fuel. Do you smell gas? Is it strong?
No codes? Rule out items that throw a code like TP sensor, Maf, IAC.
I do not think you burned uo your injectors with one cleaning.
Have you changed the filter? Check the condition of your cap and rotor! I chased a no-start condition for two days that turned out to be a small crack in the top of the rotor that let spark go through the rotor to the shaft. I had a spark at the plug when it checked.
Good luck! Mine is sitting in a parking lot right now. Man it sucks when they are broken.
