Engine died, turns over, no start

[Dbrown1978]

It just died while I was driving. All gages in the good. No warning lights or check engine light. I have spark at the plug. No fuel pressure at the rail. Replaced the fuel pump relay. Checked all fuses related to fuel and pcm. Checked inertia switch to make sure it did not need to be reset. Sprayed starter fluid in throttle body and it started and ran for a few seconds. Where do I go from here?

Welcome to the site. Not having fuel pressure narrows down the causes. Replacing the fuel pump relay really doesn't mean anything until you have checked for power to the relay.
You either have an electrical problem or the fuel pump has bit the dust.

I have voltage going to the relay. Couldn’t find out what voltage should be at each pin

As Mr stamp stated its either power or pump. Check power at inertia switch. You'll have power and then it will drop. If you have power there, its most likely the pump or the hoses in the tank, but you still change hoses, and pump. Hopefully, but probably not, your fuel in tank is low, so you don't wrestle with 150 pounds of fuel. Also please state year, engine size, and 2 or 4 wheel drive. This helps us if other issues arise. Post what you find, and your progress.

1999 - 4.6l Windsor - 2 wheel drive - and I do have just about a full tank. I’ll check for voltage at the inertia switch and go from there. Thanks for the info.

Gather up all the gas cans you can and siphon off as much fuel as you can, if and when you drop that tank. You don't want to wrestle with that kind of weight, not to mention getting splashed by the fuel. Trust me it ain't fun. Less is better! Funny how pumps always act up with a full tank! If you pull the tank, use a piece of plywood on top of your floor Jack, when you lower your tank. It stabilizes it, and you don't damage tank.

Thanks a bunch for the tips. I guess I have my Sunday plans.

Damaging the tank is not the problem, Sparks from static electricity is. Be careful. A fuel tank near empty can cause a huge fireball when ignited --like the one in myth busters.

Thank you. I got the tank down, swapped out the pump, and started the tank install and got rained out. Should have another hour of work left to do and then the big test. Thanks again.

I would change the fuel filter while you are under there.

Actually I would have changed it before the pump if it has not been done

When was the last time it was changed?

Doc Raymond is right about Sparks. Best way to remove the ring that holds down pump, is use a brass punch. That way no chance of a spark!
