Ok SV gang, for the past several weeks (when started first thing in the morning) the vette has been hard to start. Once started it runs and starts ok through out the day.. Well today it has refused all attempts to start. I suspect a fuel issue. As I can here the fuel pump come on when key is in the run position I thought that it might be a fuel filter and/or fuel regulator issue. So while key was in the run postion I open the schrader (sp) valve, and maybe a table spoon of fuel dribbled out with little pressure behind it. This doesn't seem right, but not being well versed in the fuel delivery system on my car I'm hoping someone has experienced something similar to this, and can offer some good advice on trouble shooting. Don't want to start buying a bunch of parts that may not fix the problem.. As always thanks for any and all help or advice..

Before assuming anything I would check the the ign system for spark/timing and the computer for codes.......Your car has the early optispark which is famous for failing............also, fuel pressure is checked by hookiing up a fuel pressure test gauge.

:iagree: Exactly what I would of suggested myself too.

It sounds like a clogged fuel filter to me, nothing to do with the ignition system. You can hear the pump run, so likely the pump, relays, etc are fine. It has progressively gotten worse is how a fuel filter would act as it got more and more restricted. A bad pump, or the filter/sock on the pickup at the pump are possible, but I would still start with the fuel filter first, then the sock on the pickup in the tank and the pump next. Lastly I would check the fuel pressure regulator.

"It has progressively gotten worse is how a fuel filter would act as it got more and more restricted"

I have had bad filters before and they always caused the engine to cut out at some point in the power band when the restricted fuel flow was exceeded by demand. That is not how his problem has manifested itself. Like I said before, nothing should be assumed, a few simple tests will point to the fuel system or the ign system and checking codes might help isolate the problem.

BTW a fuel tester test gauge can be plugged right into the Schrader valve on the fuel rail to test pressure.
