Question about 1994 Chevrolet Astro
I've changed the fuel pump & relay, still won't run. I was told the fuel pump fuse could be blown, but I can't find the fuse. I have no manual & there is no fuse box cover showing the location. How do I find the fuse?
You should have 2 fuses, 1 marked ECM/IGN that is 10amp, and one marked ECM/Batt, that is 15amp. Make sure they are both good. Your GM vehicle probably also has a fuel pump/oil pressure switch also, that affects fuel pump operation . Engine dies, oil pressure drops in an accident, it shuts off fuel pump. You may want to try wd-40 sprayed into the throttle body intake a little at a time to try & start it, and run long enough to build up oil pressure, (couple of seconds.) otherwise look for a red wire near brake booster or drivers fender, that is for fuel pump testing. if you carefully,supply it with a 12v+ source it should start fuel pump and keep it running while you start it, and once running, remove the wire & see if it keeps going. Make sure your oil level is up too.

Your vehicle's fuel pump relay is located on the relay center, behind the glove box, 2nd column of relays, 2nd one from the top.

when you open the fuse panel under the hood it should be on the drivers side and the third one then there is a empty space for a relay then more relays

SOURCE: fuel pump relay
In the fuse box, (under the hood), lower right corner. C1051....if you think its bad, there are others like it in the fuse box you can swap with. If the fuel pump doesnt work, be sure to check the INERTIA SWITCH. I cant tell you how many fuel pumps are replaced because no one checked that switch. If the Inertia Switch is good, have someone rap on the bottom of the fuel tank while you are cranking the engine over, if it starts then, the fuel pump is bad.
