After replacing the injectors in my '89 C4. I am able to get it started now, but it only runs for 3 or 4 seconds, then stops. This happens whether or not I try to hold the pedal down, or just don't touch it. Before the injectors were replaced, it would not start, and the crankcase filled with gas. I drained the crankcase and put in fresh oil and filter. Now it starts, but won't stay running. Any suggestions?

We'll need a little more info...did you buy the Vette not running? Did it shut off while driving? Had the car been sitting a long time and at that point you had fuel in the crankcase and decided to replace the injectors? When it starts and runs for a few seconds and then shuts off...is it running smoothly or rough/missing. I'm wondering about the spark plugs since you had fuel in the crankcase.

A bit more about it. I have checked the plugs since posting an found a fouled plug. I am going to replace the plugs and see if it helps. Before all the problems started, I had let the car sit for about three months without starting or driving it, and then when I did, it wouldn't start, but before, the last time I drove it, I noticed an extreme high peak in the oil pressure. After further examination I found gasoline in the crankcase, from a stuck injector. As far as my mechanical knowledge goes, I am mechanically inclined, but have very little experience with electronics and engine diagnostics. The service engine light is not staying on as it was before I replaced the injectors. I don't have a fuel pressure gauge, but I might get one to check the fuel pressure after I replace the plugs. Also I have noticed some coughing back through the intake at times when it tries to start. At any rate I appreciate the tips and keep them coming. I will keep you all posted with the progress I make. Thanks again.
