Question about Chevrolet Astro

1 Answer

I have a 1990 Chevy Astro. The other day I got in it and it would not start. I sprayed starting fluid in the fuel injectors and I was able to get it home. I changed the fuel pump and the fuel does go to the fuel injection pumps. I know the pump is working cause I bypassed the relay and the pump does work and get fuel to the motor. What else can cause the fuel not to get in the motor.

The relay works the fuel pump only after normal oil pressure is reached

The engines oil pressure switch's 3rd wire primes the fuel pump the first 5 seconds after starting the engine

The fuel pressure regulator keeps a constant pressure to the injectors so that has nothing to do with your problem since you drove it home

I have a chevy astro van 4.3 there is fuel pressure coming to the fuel injector spider. I like to know how to test the selenoid in the spyder, and where the Selenoid gets the signal of the spray pulsa


Just replace it, no real testing is done as long as one side of the injector has 12 volts and it doesn't spray when you ground it with pressure in the rail..

Had no spark. Replaced ignition mod, 2 coil packs, and computer. I now have fire; problem is engine will not run, the fuel injector sprays fuel (too much i think). When i unplug the injector the engine...


Check for any wiring pinch which might have occurred when the injector was replaced. The injector is driven directly by the computer, so it seems to point at the new computer as being faulty. (pulse signal is always 'on')

Chevy astro van turns over but wont start when


Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump
