1994 Caprice 150,000 miles but mint
4.3L V8.

Turned the corner in a parking lot and the car just died and wont start

- No Fuel Pump noise when you turn the key forward
- Turns over fast and clean.
- When I try to throttle it like a carburetor not even a burp or a fart as im cranking.
- Tried hitting the tank with a 5 pound sledge well cranking it but nothing.


Car is back at my house but going to my mechanic on monday. If I take off the inline fuel filter under the body, and turn the key forward to test if the fuel pump is gone, should fuel shoot out the line? Any other ideas besides the fuel pump.

Yes; enough fuel should shoot out to start a big fire. I you do this; make sure there are no trouble lights around.

The fuel pump relay. Fuel pump fuse.

At 150,000 mile if it, is the original pump, my first guess would be the fuel pump failed. I would suggest you only use an OEM (original equipment manufacturer) pump in it.
For those of you that are wondering why you are not getting replies to your thread:

Did you give the model, year, engine, fuel system type, and transmission information?

If the it has been altered from stock let us know about that too.

I agree that it is the FP relay or FP itself. The thing to do to test it to put a pressure gauge on the schraeder(sp) valve under the hood.
Check the wiring harness to the FP if you end up having to change it.
Don't hit anything with a sledge hammer. Buy a Haynes Manual and keep it in the trunk for use in doing repairs and diagnosing problems.

Ok Went outside this morning and checked the relay from what I see its mint and intact, the copper wire spool isn't burnt or unattached and the little resistor is still good.

I did check the Blue 15amp fuse that said F/P under the hood and it was burnt, put a new one in and as soon as I turned the ignition to on it popped/blew.

Were should I go from here guys?

FP is shot is my guess. The relay blew for that reason or it's the wiring harness(or both) and you won't know that until you drop the tank to do the pump.

Glad to hear that the problem has been solved! The price sounds about right also.
