HELP PLEASE! I'm stuck in the wilderness with a dead fxj80

Update:

Fusible links are ok.
Fuel pump seems fine so I think we're only dealing with spark.
All fuses have been checked
We have checked many connections and all have been fine.

We get 12v to the coil, but nothing past that.

Just got back to cell service. You guys are awesome. I'll keep trouble shooting per all the feedback. Oreillys will have a coil tomorrow morning for us in ridgecrest.

Coil why? I have yet to experience or even read about one person on MUD needing to replace a junked coil. There is something else going on.

Does anyone in your group have a multi-meter? Does anyone in your group know how to use one? Does anyone have the FSM on a laptop, iPad, iPhone?

Oh good!! Ok then no worries. Glad to hear. You won't need the tow, it'll get solved.

You guys are awesome. Thanks for your willingness to come help. We'll try to tackle it on our own with the help of the info you've shared. Of course, if you're just looking for an excuse to get out, you can find us at the base of defense mine trail.

Check your crankshaft position sensor and wiring

I would bet that you have jarred an electrical connector loose. Check them all, unplug and replug all the connectors in the engine bay (the one on your distributor would be a place to start). There is also one connector on the underside of the rear passenger side footwell that I believe goes to the fuel pump (correct me if I am wrong). Check that one, its caused me problems before.

this is what I was thinking, the fsm procedure to drain pressure to the fuel filter before replacing it involves unhooking this connector.....

When you say the Fuseable links are ok, did you use a multi-meter? Or did you just check for burned wires?

Interesting you mention this... I had a couple obd codes that we cleared when we were trouble shooting after the incident. I wasn't sure if they had been there long or were from the shut down. I'm sorry I didn't mention it earlier.

They were:

Crankshaft position sensor code
Camshaft position sensor code

12v with no drop across them.

We checked the connection at the rear passenger door. No problems there
 
Does anybody know the coil resistance? How about testing the position sensors?
 
Crank position sensor fault should set the MIL and a code, but if it is not responding the engine will be dead as a door nail. Try cleaning it. It is at the bottom of the engine at the front of the oil pan. Maybe it got knocked loose. There is no cam position sensor on the 1FZE; only a crank sensor. You only need one.
 
Straight from the horse's mouth :)

Would pay you to in future download the EWD and Manual for the '96 (close enough for your model) and store on your phone :)

cheers,
george.

Thank you guys! I'm heading back to the truck to try some more. I'll be out of reception for awhile.

CPS is internal to most fuel injected vehicles distributors, external to COP systems. It's generally a photo sensor type setup.
