Hi noko1,

Do you mean the fuel pump relay does not have any voltage at terminal # 11? When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

This guide should help us

At the left side of engine compartment in the Battery Junction Box, check the Fuel Pump Fuse ( 20 A ) use a test lamp to check if battery voltage is available. If fuse is bad replace it. If fuse is good and does not have any battery voltage, there is an open between the battery and the fuse, could be a fault with the fuse box or loose connection.

If fuse is good and voltage is not available at the relay, check the Light Blue/Orange wire to fuel pump relay for open circuit.

Note : If power is getting to the relay and coming out, check the inertia Fuel Shut Off Switch, located at lower left rear corner of trunk.

Sorry I am having difficulty understanding you and there is nobody around to help me out at the moment.

Hope I get you right.

You mean the engine is quitting after startiing. If the ddash indicators lights are not showing, you could have a faulty ignition switch that is not working at the RUN position.

You need to test if voltage is present at the ignition switch Black/Light Green, Red/Black, Red/ Light Green and Gray/Yellow wire. Wire.

Mustang not starting
-Fuel pump works, but only shoots a pump about 1/4 of what's normal. Force-grounded it, so there's spark and gas at engine, but still won't start.
-New fuel pump relay
-Will discuss further

As a note, we're not sure it's the fuel pump; it could be anything.
Also, my uncle, the one that's helping with the car, has to leave pretty soon here, so after a little while we might not need help anymore.
Thanks

I recently replaced my fuel pump and filter. It crank 2 times after. Now it just turns over. No fuel. Reset the switch and still nothing. What could be going wrong? Before I replaced it I had 4 hot wires going to the pump now I only got 3 hot wires going to the pump. Checked fuses and relays. Is the anything else I could try?

Okie Dokie.I checked everything out. Got to looking and found the Fuel Pump Driver Module. Replaced it. Got power. But for some odd reason the power going to the fuel pump got hot and started melting.. Unplugged fuel pump and turned the key over and got power to my meter. The wire did not get hot then. There was a naked spot on the power wire in the fuel pump. LOL Thx to me. Could that be grounding out or shorting out In the fuel tank? Thanks John

My car stalled like it was out of gas when I put gas in it an hour so later is started back up. Now its doing it again and this time it won't come on at all. I can no longer hear the
fuel pump when I turn the ignition. Do you think this is the fuel pump or relay?

If you ran out of fuel, the pump was damaged and most likely needs to be replaced.

I would have the pressure verified before throwing any parts at it
