Hey guys, just made an account. I have a 95' Cherokee Country. Ran off the road and hit a tree this Monday after getting new tires. Got it towed home. Pulled out the bumper with a chain, put the serpentine belt back on. Just trying to get it started to know if it's working and worth fixing. It's cranking but I've got no spark at the plugs. Used an in-line spark tester. The impact happened right where the ECU is. Got a bunch of suggestions from my buddy to try, crank sensor, auto shutdown relay, grounds. But he told me to ask on some forums. What else could cause no spark?

 

Those are 2 very good places to start. The ASD relay especially because that's as simple as replacing the relay/fuse.
There is a diagnostic test you can perform on the cps with a meter to test if it's reading properly or not - I would do this before throwing new parts at it.

 

I'm still fairly new at all this. I've done a bunch of work on this Jeep, hoping it'll last me a long time. What do I need to do to test it? Do you have a link or video I could follow? I tried turning the key on-off three times to get the check engine codes, but nothing happened. Makes me think the ECU/ECM isn't getting connection.
Thanks

 

So I was able to get a crank sensor fairly cheap. Swapped it out still nothing. I took the AC relay and put it into the auto shut off relay spot, they had the same part number. Nothing, I do have 11.7 volts running into the coil, not sure how to test the voltage coming from the coil to the distributor though.

 

whoa boy, stop right there.

let me link you the '93-95 Powertrain Diagnostic Manual"

This is written by & for Chrysler techs to fix them when they were new, it can and should be used in conjunction with FSM, which is a free download from crusier54 website, search it.

I will edit in this link for you to download...its flow charts, so even a simpleton can use it..but its GOOD. It refers to the DRB Jeep tool, but you do NOT need it, just a multimeter

(hopefully the link works after this trumpeting, PM me if it doesnt)

Everyone who owns a 93-95 should have this manual!

OK I think it should work this time...would you mind terribly "liking" it or commenting if it does (or does not) so I can fix any access issues thx ?

 

Thanks AWG!
