I'm pulling the CEL code for Multiple Engine Misfire.  I took out one of the spark plugs, grounded it and cranked it, no spark.  I've replaced the plugs and wires, still no spark.  I know i'm looking at crank sensor, coil pack, or computer.  The cars been sitting for about 4 years and hasn't been started.
My first question is will a coil off of a 98 Neon SOHC work(because I can get my hands on one from a running car) and the second is which part do I start with?

same coil it will work

first I hope you have fresh gas in the tank
second after 4 years you may have severe corrosion on the harness
remove the crank sensor clean it clean the connector, do the same thing with the cam sensor and tps too

you could disconnect the computer and clean it well
buy some electronic contact cleaner and spray generously

The gas tank sat empty with Sea Foam in it as with the cylinders.  I'll try the contact cleaner in the morning, cross my fingers and hope :) 

hope everything works out. also why was it sitting that long. did you put in a new battery? try a volt meter and try all the electrical components..

Reason it sat so long, 132 mph in a 35.  Being 18 and putting a 347 stroker in a Pinto isn't a good idea.  The battery was taken out and used for something else.  I have a brand new yellow top Optima, hopefully it doesn't do like some of them do  :-\  I guess its actually sat for 6 years, eek.  What components are you suggesting to try>?

6YEARS HOLY CRAPOLA :o :o :o try every thing you can.also are you getting a spark with any of the plugs

I have no juice at the wires that go to the coil, everything else checks out. 

check coil in no good then get new one replace and fire the beast up. if that dont work then let us know and well try some more stuff for ya

So the wires coming out of the coil on the drivers side are not input wires to the coil?

WAIT i mis read your last post im sorry. test all components of the electrical system 1 by 1 starting from the spark plugs. when you get to the first part that shows life then go to the part right before it and replace it. if that was the only problem then it should start right up. if not repeat the process and hope that you dont get as far the second time around cause then you have an even bigger problem. hope that helps. now that i think about it does it even TRY to turn over??

Sooo, If I have no power to the wires that come to the coil, where would I go to next to check to see.

Wiring harness... Fuses/Relays, ECM

Check your ASD relay.

how can i put this. if you dont know wiring then its like one big effing maze that seems impossible to get out of. once you get the hang of it you realize its just one big loop with a couple of tangents here and there. ill try to look up the diagrams for our cars. wait mabe nykon can get it before me. hes got the resources and im more computer illiterate

Dodge/Mitsu w/e you wanna call it has some messed up wiring, I miss Nissan wiring, ahhh so simple.

I figured it out, wooot!  I'm guessing a mouse had chewed throught the wire or something a little bit into the sleeve covering for the wiring harness by the computer.

I had some animal crawl up in side my car (not this car) and chew through a bunch of vacuum hoses and wires.  When a coolant line breaks wipe it ALL up.

thank god i havent had that happen yet :P

ohh and good job finding the problem

GRRRRR Its doing the same thing again, retraced the wires and no broken ones, resoldered the one that was broke, still nothing.  And now instead of it not firing, it also has a cracked front bumper.  I took the car to the local Dodge dealer and they don't know whats wrong with it.  Coils good, Crank Positioning sensor is good, computers good, ASD is good.  They were all replaced with new parts.  Any thoughts here?  Blinker fluid, muffler bearing hehe.
I got offered a 2jz swap kit for the 81 Celica today for trade on the Avenger, i'm about ready to say SOLD!

Anyone have any input on what else could possible be wrong?  I've been trying to find a wiring diagram so I can check the wiring out with a tester, but my local parts stores claim they can't get the manuals for them anymore >:(  Anyone know of a website that has wiring diagrams?

I swapped the ASD relay with the drivers side one (cut off the tab or whatever you want to call it)  It started up and ran fine.  I shut it off and went to start it back up and it won't start again, no spark again, no power to the coil.  Just to clarify the crank sensor we're talking the one in the middle, not the one buy the oil filter right?  Any help?

Nope the crank sensor is the one above the oil filter.  I only know because I dropped an alternator on it once....

So I put an ohm meter on the cam position sensor and I'm getting nothing, power in the wires.  I'll pull the crank position sensor in the morning and double check.  My local Dodge dealer said everything was fine, but I don't really trust them now.

first of all tell them to eff off and then tell them to find the problem for no cost cause they messed up in the first place...(nahh im just kidding)

Since they couldn't figure it out and after a long heated discussion with the shop foreman they only charged me $20, so I'm not out much.

I put in a new computer, Crank Sensor, Cam Sensor, and an ASD relay and it now runs.  I still have some amount of stutter at idle but now I have a leaky head gasket, this will be the third one and the car only has 96,000 on it grrr.  I'm guessing the block is warped, I hope not, thats my only explination on why it keeps leaking, my head hasn't needed milling either time.
