Question about 1995 Chevrolet Astro

1 Answer

1995 astro van stalls when given gas. Any solutions? I have replaced the fuel filter, fuel pump, fuel injectors and am working on checking the fuel lines right now to check for a pinch or clogg. Any other suggestions? I was told to check the fuel pump relay but I cannot find it. I checked under the hood near the firewall passenger side and their are 2 relay boxes both with 4 wires both look the exact same, neither look like the replacement autozone sold me lol..

    Pressure is fine while van is in idle, however when you shut it off the pressure goes down to 10 and when you give it gas it goes crazy (shots up and down)

Check the fuel pressure(min of 45psi)under the hood at the port. if thats ok, check for intermitten spark(esc)electronic spark control may be getting hot and missing a beat....if thats ok then check the MAF sensormalfunction, but you should have a code for all but fuel pressure.good luck

1992 chevy astro van getting fire but not fuel stalled while driving replaced fuel pump when we pour gas into the intake the engine will fire but not getting gas

Did you change the filter? Can you hear the pump cut in for a few seconds when you first turn the key the "run" position? If you can'r hear it, you may want to check fuses and power wires to the pump.

Cannot get 1987 chevy van 20 to keep running... stalls out

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

1996 astro stalling/stalls

Right turn signal - activate turn signal and check to see if bulb (front and rear) are flashing. If not it will affect the flashing timing. Replace bulb. As for stalling, may yet be sediment/gunk in tank that is clogging new fuel pump filter and inline filter. Or an idle/throttle position sensor. Hatch problem, I've no idea. Family members 1998 Grand Caravan has been infected with similar gremlins in the sliding doors. Best advice is to obtain a Chiltons/Haynes repair manual and go through the troubleshooting section.
