Fuel Starvation Problem
I own a 88 vette-----------I have an intermittent problem that happens about every 10th time or so that I start the car. Acts like it is out of gas----does start up and then shuts down (sounds like fuel starvation to me)-----crank it 3 or 4 times doing the same thing and then all of a sudden it starts up and runs fine. Runs fine after starting and does not quit while driving.
What I do know: is not tied to whether the car is hot or cold,
have good fuel pressure even when it's having a problem, have spark when it's having a problem, finally got a fault code last week for the first time but can't repeat it----faulted 34 & 54. Checked out the maf wiring and it looks fine. Sounds like the ECM is not getting or giving the signal for the fuel to flow???-----any ideas on what to check first??
Thanks for your help

thanks for your reply CFI------I do have the manual and of course since I can't duplicate the fault code------it basically refers you back to the troubleshooting intermittent failures. Thinking I will just assume the fault code does appear and trace down the suggestions it gives for checking wiring problems and testing circuits. Yes code 54 is the fuel pump circuit-------and fuel pump pressure is there and apparently the ECM is working correctly if I have pressure??????so why does it sound like only the primer is being burned???-----
