You probably have codes set. I believe the 2001 behaves like my 1999 if there is an immob problem, it cranks, fires, then quits.

Have you tried jumping the solenoid to test the starter components?

I jumped 12v to solenoid wire. I have spark and 45lbs. At the fuel rail,but no injector spray. Ether won't even get a pop out of it. Any suggestions?

Check for 12V at the injectors, but if it doesn't pop on ether and you have spark, compression test is next.

No voltage at the injectors. Voltage at the #6 fuse for the injectors. What could cause this?

Computer not firing the injectors ? Double check (remove/replace) the wires to injectors, go along the cable see if it's fine, check the grounds around the engine.

Thanks for the advice! The injectors are reading 7.3v.engine fired with ether. Are they supposed to be getting 12v?

Grab the wiring diagram off the web. Should be battery voltage at injectors, the ECU fires by grounding

Okay I have confirmed there is no injectors firing. It will only run for a second or two,so I'm confident that the ECU isn't providing the ground. I suspect the no crank condition may be linked to the ECU not allowing the ground. I have a CEM-6C46 antenna/light ring internal fault code. I replaced the antenna ring with a used one (bad idea maybe Romo) and tried both keys. Is it probable it is the ignition switch? Can I test the signal going to the ECU from the switch? I'm just trying to narrow it down,as I need to get it running and have at least a week or two until they get to Alaska.

I can jump 12 v to get the starter to crank, however it appears I have no injector operation. Ether gets it to fire,but won't run for more than a couple seconds. The CEM-6c46 antenna ring internal fault code code is present. I suspect the the two may be linked. I would like to isolate the problem, instead of throwing parts at it. Is this possibly a ground that is not being provided to complete the starting circuit, therefore no injectors being grounded to allow them to fire? Or possibly two separate conditions, like a bad crank or cam position sensor causing no injector function?

That fault code is telling the ECU the start isn't authorized. The start run stall cycle is exactly correct for a bad key chip or a fault in the key reader.
