Engine has stalled

No fuel check the fuel pressure with a gauge to rule out the fuel pump-

Does the pump receive power? If not, is the relay being energized? If so, you'll have to trace it.

Ya the fuel pump work and i get no power to pump i switched relays and nth

Check the inertia switch

Already did

You haven't answered the questions yet.

Is the pump receiving power?
What is the fuel pressure?

[qoute]Ya the fuel pump work and i get no power to pump i switched relays and nth [/quote]

I'm going to take this to mean that you've both hotwired the pump and the relay to verify that the pump works. With the key in the Run position, see if you get power to pin 86 and that pin 86 is properly grounded. IF not, find out why. Trace the wire for Pin 86 back to its source.

Has no pressure and fuel pump harness has no power

Jump out the relay and test for power at both sides of the Inertia switch.

Ok should i have power on both sides?

The the relay. Pins 85 and 86 energize the coil. 87 and 30 carry the power for the load. You should see continuity between 87 and 30 with the coil energized. IF the coil isn't being energized, either it's not being grounded, or it isn't getting power.

The red and dark green/yellow wires should have power when the key is on and the light blue and green should go to ground. The black/yellow wire should have constant power.

Ok i jumped my pump from the eec and grounded it and the pump come on a runs so what does that mean

It means that the pump is good. Now you need to check everything you bypassed. Including whatever wiring you bypassed.

I found the problem but idk how to fix the relay isnt closing for the pump to come on and it has power so what tells it when to close and open

Are you sure you are checking it properly? It only powers for 2 seconds when the key is first turned on.

Yes. My mom turns it on while i am holding it and the other relays around it r clicking besides the fp relay

Ok. SO no clicking from the relay with the key on. And power and ground to the proper pins at the proper time. You need a new relay. They're usually about 20 bucks.

I got a new one today and it was the one i was testing it is doing same thing as old one and i.ohmed out and put on anotger relay and it works

Ok. Pin 85 what have you got? Pin 86? 87? 30? Let's go from there.

What woukd cause a relay to not close

Incomplete closure of the switch-no ground or power on Pins 85 and 86 when the switch controlling the relay is activated. That can be a bad switch, broken wore, or bad ground. A faulty relay can also fail to close, even if everything else is good.

Take a look at the diagrams below. They are typical 12 volt relays. The bottom 2 images might make it easier to see what happens. Pins 85 and 86 energize a coil. Pin 30 has fused 12 volt power, and Pin 87 has the load attached (in this case the fuel pump).

Ok i have check all inline fuses and bad wires i cant find anything i have no pwer to inertia switch and when i ground out pump it runs

So should i have power on 30 85 &87 and there should only be one ground right or no cuz i have only two powers and two ground unless one is suppose to have power

Pin 85 goes to ground. Pin 86 is switching power from the ignition switch. Pin 30 is fused power constant. When Pin 85 goes hot, so does Pin 87.

What size engine do you have? If we know that, we can look up the wiring schematics for it.

V6 4.0

Like that. Thanks Wrenchtech.

I have that but i chased all wires none broke or anything could it be the computer not grounding out

Yes, it could be. IS your fuel gauge working?
When you said:
"i jumped my pump from the eec and grounded it and the pump come on" does this mean you applied power from the EEC and ran a dedicated ground wire and it worked?

Oh, and what pin of the EEC did you use?

Ya i ran a wire to ground on battery and it would run idk it was one on far left

No it wasnt wrkin

Ok. It sounds like we need to figure out why power isn't getting to the pump. Make sure the fuel pump fuse it good. Make sure Pin 86 goes hot with the key on. Make sure Pin 30 is hot full time and that Pin 87 goes hot when the key is on. And then verify continuity in all the wiring.

Ok well i only have 2 powers

With the key on? What Pin #s? If you're testing the relay socket, with the relay out, that's correct-no relay to close, allowing current to flow between Pins 87 and 30.

Remember to check continuity with the power off, or you'll damage the meter.

87&85 i have power

With key on? Ok. Now check for continuity between 86 and ground. If that's good, you have a faulty relay. If not, you have an open wire between Pin 86 and ground.

I don't see anything attached to ground in that diagram. Trigger ground is provided by the PCM for 2 seconds only.

Yeah, but it's got to go to ground to complete the circuit properly.

The PCM does that and only for 2 seconds. I'm sure you're aware of that but I didn't want the poster looking for something that doesn't exist or try to add a ground manually which would be a disaster.

Yeah. For 2 seconds, until the engine starts, then it's constant ground.

Or, stated better: 2 seconds with key On. To provide enough pressure to start the vehicle. And it provides a constant ground once the engine is started.

It's actually starting to sound like maybe that's what's not happening.
