Feul pump won't run (new feul relay and feul pump)

Here's where it's at. here's what it look's like.

Yes, it can be the relay. What I do is unplug the relay and swap it gor yhe horn relay. If this doesn't work, I use a volt/ohmmeter to probe the relay socket. Doing this, I can usually find the problem. With the key on , there should be two terminals in the socket that have battery voltage and one that is grounded. The last terminal goes to the pump and should show low ohms to ground. In your truck, the relay coil is connected to ground and turned on by the ecm with a positive signal. It also seems to depend on the oil pressure switch, so you might want to temporarily bypass the switch with a paper clip in the connector to see if that is keeeping the pump from running.

Running never stop,it not the wiring,check the power soure that give the feul pump it power.

Your ford should have a schrader valve in the fuel rail for testing fuel pressure. You shouldn't need to remove a fuel line. On the left inner fender there are two, maybe three relays, usually encased insome type of enclosure. The relay with the green plug is the fuel pump relay, the relay with the brown plug is the EEC relay. Unplug both of these relays and inspect for corrosion, broken pins, and corrosion. A problem with either relay will cause the fuel pump not to run as the EEC relay controls the fuel pump relay. Corrosion at these connections has been very common at my shop.

Here is a diagram from Chilton's manual.

The electric fuel pump is controlled by a relay in the fusebox.
It normally only goes on for a few seconds, and then if the alternator does not signal the engine is running, the relay is supposed to shut the pump off. But you can shunt the secondary wires of the relay to keep it on if you want to check fuel pressure.

Try some starting fluid spray to make sure the ignition is good.
It will at least sputter on the spray, if there is spark.

Here is a picture of an Aztek fuel pump relay:

Did you install a new pump? Used pumps may be cheaper but not if you have to change them.

Try the crankshaft position sensor. Sometimes they get covered in clutch dust and the sensor cannot determine No1 cyl. and then it will refuse to start. Sometimes they go faulty as well.
