ok, my buddy brad is working on getting my wrecked 96' XJ (inline-6, ax-15) fixed but he cant get it started. he drove the XJ into the bay to remove the bashed frontend (fenders, bumper, lights, grill and hood) and to test fit all of the new body parts back up before paint, well the jeep would not start after doing all of this. he has tested it out and is finding out that the coil is not getting any fire (the motor turns over but wont start).....he swaped in a new 'puter and still nothing happened (he said it could be have been a bad 'puter also)

He forgot to hook up the ballist resistor over on the left fender well. It should be there right next to the air cleaner....big white resistor with two wires going to it.

just called him and he said that it was never unpluged and he checked to see if the wires were on tight so thats a no go?
got any thing else??

ok none of this works yet (but thanks for the help guys)........brad hooked up a reprogrammer to the XJ's computer and didnt get a reading at all so we are guessing that the 'puter is bad so here is the next problem........
the 'puter out of my 96' XJ has a parts #56041293, well when we called to some parts stores (NAPA, autozone, advance, o'rileys) they said that they couldnt get that part number (XX293) but the part coming up for a 96' XJ, 4.0 I-6, 5-speed was #56028852 (hell even the dealer could find the XX293 number)
so heres the problem, should i just go by the XX852 computer hopeing that it works cause once you leave the store you dont get a refund on elect. parts from any of the places that i have talked to....so if it doesnt work then iv tossed about $260 in the craper
just to recap, lights, horn, wipers, power loack and windows work, the engine turns over put gets no spark
thanks
the stupid fat guy

If you start a pot, can I get missing GROUND?

I find it hard to believe that the computer is dead.
Are you sure the computer is getting power? No blown fuses?

A shot in the dark, but a good one -
Check the crankshaft position sensor.
It's on the left side, behind the engine, down on the top of the bellhousing. Hard to see - harder even to replace, but do-able from the bottom.
If the engine shifted forward in the accident, it may have broken the connector or wires from the sensor right behind the engine. It could even have bent or damaged the sensor.
Look close, you'll see the wires running down back there and the connector.
Without a crank sensor signal, the computer will act dead.
I think the sensor is about $35, much cheaper than an ECM.
You can check it - disconnect the connector - attach an analog (meter type, not digital) ohmmeter to the wires from the sensor.
Rx10 scale on the ohmmeter
Crank the engine - the ohmmeter will swing wildly as it cranks - if it's OK.

[/ QUOTE ]Yep, Good call,RRich. ASD supplies 12v to coil, PCM makes and breaks ground based on crank sensor input. ASD will only supply 12v for a second when key is rolled on and engine isn't cranked. HTH!

damn rrich thanks for the info......we never thought about that cause it was not near the wrecked parts, damn i hope that it....ill get with brad after he gets in to see if that is it : Beer :

DumbA$$.... I mentioned that to Brad 2 months ago when I stopped by his place for him to "adjust" my driver door after hitting it on the tree.
I looked and checked it, it was still intact, but a little tight it seems. I told him wiggle it around while someone cranked it, and to consider replaceing it too. Smack him on the head if he didn't!!

CPS? Kinda like saying your out of gas when you can't turn the engine over. Yes, the CPS will cause a no spark condition....but, if you can't get info from the computer....the CPS is not in the picture right now.

(Lord, I think I'm starting to sound like Leve now)
It ran before it went it. Now it does not. Get back to basics. Look for disconnected wires. If you can't get any data from the computer (check light work?), then start checking fuses and broken wires. Even with a bad CPS, the check engine light will work.
Remember the axium..."The solution is inversly proportional to the apparent magnitude of the problem"
Get the computer alive first. Look for the simple stuff.....like missing grounds

Is that the OEM puter or the "one of unknown origin" that's fried? /ubbthreads/images/graemlins/crazy.gif
'puter sounds expensive....may want to check its power supply for ground faults before you plug in a new one
Think about it:
"""""he drove the XJ into the bay to remove the bashed frontend - (then) the jeep would not start""""""
Do you suppose gremlins snuck in during the middle of the night and blew out the computer?
Space monkeys?
Lightening struck it?
A revengeful God's punishment?
What are the odds?
Either something he did wasted the computer, or it's no longer hooked up right.
I'd do a voltage check on each pin - bet something's not connected or connected wrong.
If he did blow it and did not already find and cure what did it - then just plugs a new one in - he'll be the proud owner of 2 perfectly useless fried computers. You can get them cheap on E-bay - super convenient - they are already blown for you!
Why not take that computer he already has and try it in another like vehicle? Chances are it won't hurt another vehicle. If it works on another ----

well we are getting into an area i dont know about so thats why i had it hauled down to J-Medic (local jeep mech for 15 yrs) to let a mechanic (not a bodyman) find out what is wrong....the mechanic has done all of the above you talked about and said that the 'puter is fried.....i guess its one of those things that happened......he is looking for the source of the mess up....

It's rare ..but I've seen it happen myself.
If the body man was arch/tig/mig welding on the body without putting one of those spike shunts across the battery ..I could see this happening.
