No crank,no power to fuel pump fuse , maxi-fuses got power.changed relays, checked neutral start switch no crank.no injectors working.JUMP FUEL FUSE,PUMP WORKS. JUMP START RELAY ENGINE CRANKS ?

Check the Maxi fuse #13 in the under hood fuse block it powers up all the ECM power outputs like fuel pump, injectors and ignition. I hope this helps. Take care.

You know that how?

What testing told you that?

I would only be guessing (that is all we do here)

But it sounds as though the ignition switch is worn
& effects the fuel pump circuit, when in the on position,maybe!

Get yourself a wiring diagram & see how the system should work,
then test it at different points that are accessible

check your crankshaft position sensor. fuel+spark+compression+timing=ignition.

Do you have a test light? If not, go buy a cheap $5 test light-one with a lead to clip to a ground, and with a needle type probe.
Pull the fuel pump relay out of the terminals it is plugged into-you need to check if the power feed for the pump is still available at the relay. Clip the test light lead to a ground and touch the test probe to the positive battery post-to check that your ground is good- tester should light up. Now touch the probe to all of the terminals that the relay plugs into. One terminal should have power with key off. If no terminals have power, you have lost the power feed for the pump. Double check all your maxi fuses in the power distribution box. Either a maxi fuse or a fusible link will be the power feed for the fuel pump relay.
If the power feed is there at the relay, try a new relay. If still no pump, a shop will probably have to check your fuel pump circuit.
Did you check for power at the fuel tank while the key was held in crank? When the engine is cranking, the fuel pump wire should have power. When the key is turned to on, the fuel pump should have power for about 2 seconds, to pressurize the fuel system. Then when key is turned to crank or start, the fuel pump should stay on.

Begin by checking fuses. Ignition, efi, fuel pump fuses. When key turned to on, do the warning lights and gauges work? That verifies switch has power and is sending power out. With key on, the coil primary wire to coil packs should have voltage.

No spark and no gas? Fuel pump fuse good? I think I would use a test light or multimeter to check that fuel pump fuse terminal has power to it with key on. If that's good, pull connector off at fuel tank and check for a voltage signal on fuel pump wire when the engine is cranking-if good signal, fuel pump needs taken out for replacement or inspection. If no signal check that fuel pump relay has power to it. With key off, pull the relay and check that one terminal has power to it-the feed wire for the pump. If no power signal at all, check maxi fuses or fusible links for a failure.

check all fuses under left dash if that doesn't work check to c if you are getting power on the injector plugs if you are getting power then go to a junk yard and get a throttle body

You said you hear the pump come on, then said fuel pump not running ???
Check the fuse for the pump, preferably with a test light to verify power is there. Key must be in on position. If the fuse is powered, feel for the fuel pump relay to click when you turn key to on. Put your finger on it while someone turns key to on. If it clicks, check for power at the tank connector on the pump wire, while the engine is cranked. If power there when cranking, the pump must have failed and needs replacing. If the relay clicked with key on, and no power at the pump wire at tank while cranking, then check wiring from relay to pump connector-the fuel wire may have broken.
If the relay doesn't click when key turned on, check for the power feed for the pump at the relay terminal. If the relay has power available to be transmitted to pump, then the relay's signal from the computer or the ground side of the relay's coil signal (from the computer) may need checked.
If the pump is working, and you have good pressure in the lines, check the injector circuit. Also a fused circuit, so check the fuse first. The injector should have a steady voltage signal to it with key on. The injector only has two wires, the power wire and the ground wire which goes to the computer. When the computer momentarily grounds the injector circuit, the injector "pulses", causing fuel to spray out the bottom.

Yes there is a starter relay in the wiring diagram.
The yellow and lite blue wire goes from the starter solenoid to the relay. There is a yellow wire from the relay to a 30amp fuse. The key switch powers thru the neutral safety switch and then powers the relay on.

If the passkey system were not working the engine should not crank and the fuel injectors would be dead. The security light would also stay on.
The fuel pump relay gets battery voltage and also voltage from the key switch. The computer grounds the relay to power the pump.
The crank sensor does not come into play until the engine is cranking and it supplies a signal for the ignition and injector pulse.
Are you not getting power from the key switch to the relay, or from the battery side to the relay ?

First unhook the battery for about a half hour to reset the computer.
does that have anti-theft on it.
a remote starter ?
second either swap the relays for the starter and fuel pump or replace them outright.
when you bypass the relay to get it to crank... will it start ?

if that radio is of the anti-theft variety make sure you know the code and how to enter it
