Question about 1994 Chevrolet Astro

1 Answer

No fuel to engine

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.

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.

My 2000 monte carlo will not start


You probably have a blown fusible link (between the starter cable post and the fuel pump relay), or a blown relay fuse or a bad relay. The fusible link and relay should have power always and can be checked with a 12 volt test light.

Have a 2001 jaguar vanden plas. It won't start. It cranks fine battery is good but it won't turn over. I have been told could be fuel filter and or fuel pump. If you agree how do i change


To confirm that is is the fuel pump at issue here get a can of spray starting fluid and next time it won't fire up spray it into the air intake hose of the engine while someone cranks the engine over, if it lights right off then the pump may be the problem. A clogged fuel filter may cause loss of power but seldom if ever a no start.

Fuel not getting to intake


check to verify there's fuel pressure at fuel pump, always check for blown fuses first. if the fuel pressure is not present at the fuel rail then the pump is bad, providing that all fuses are good.
