The fuel pressure regulator on that Vortec engine is under the upper intake plenum, on the back side of the central fuel injector. It is held on with a slide clip.

1997 Z-71, 5.7 vortec. Let truck sit for 3 days. When started up, idled rough. Take off is slow. changed plugs, no good. what next?


I would check the fuel pressure regulator, remove the vacuum line from it and start the engine. Look for fuel coming out of the vacuum port on the regulator. If you see fuel, replace the regulator due to a ruptured diaphram

1997 astro 4.3 vortec v6 fuel pressure problem. The fuel pump works for about 2-3 seconds when i turn on the key and it works when i crank the engine but i do not have anything close to 50 lbs of pressure...


Hello frankdoiron: My name is Roger and I will help you. If the fuel pressure is not 60-66 psi. the engine will not run right or will no start. At 55 psi. the engine will not start. Unless you have a injector that is stuck open I would look at the fuel pump as the problem. I would also change the fuel filter the same time you replaced the fuel pump. The warranty on the pump would be void if you do not replace it at the same time.
Please rate the answer you received. This is how we know your answer helped. Should you need further help please just ask. Thank You for using Fix Ya. Roger

My dad is having trouble starting his 95 GMC Safari Conversion van after it has been running. After setting overnight the van starts right up. If he runs a short errand, turns it off, then tries to start...


My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
