dunno if that will help but you could try it, it wouldnt work for me

 

check for codes..........http://go.jeep-xj.info/HowtoECUcodes.htm

 

i get like a 2.3? idk

 

so you got 23 then 55 right?

 

I am just going to take a guess that the "jump" was pretty rough. That being said the automatic fuel cut-off should have tripped and shut down your fuel. where is it on a your model,I have no IDEA. but you said you are getting fuel, are you sure? could it have been residual fuel in the line and not actually pumping? are both lines from your batterys positive side still connected? I did not see what year or model you were rolling so these are just some ideas. sounds more like a crash than a jump, but what do I know.lol.

 

ive had this issue before if the gas and volt gauge are not working then the ecu is inop causing no spark. i wanna say it was like the acs fuse under the hood. look at the fuse panel under the hood and check fuses

 

no it just showed a 2.3 and then went blank.
its a 98 and nope i got fuel shooting out strong and i hear it clicking away! its all a spark problem

 

did you check both fuse boxes?

 

your code show 2.3 in the dash the check engine light does not flash

 

i have a newer model on...... i couldnt locate an "ACS" fuse

yup

 

do you have the factory keyless entry immoblizer stuff

 

dont think so... just the lock/unlock clicker thing. im gonna have my friend with the same year/engine/ax-15 as mine come over and we'll swap ECUs cause its gotta be that!!!! if not u'll see a sad for sale thread on here.

 

what is the production date of youxj like 12/98 it shold be on the door

 

Have you checked your coil?

 

it is 6-98
