97 wrangler has fuel to the injector rail. cranks ok but doesn't seem to have any spark. Any ideas? Doesn't seem to have any volts to the input side of the high tension coil.

Hi there, no power at high tension coil?? mmmmm don't sound good but hey first thing first, did you check all fuses and breaker fuse? main fuses under bonnet on passenger side make sure engine fuse and breaker fuses are ok for starters, and just so you know you have more fuses behind your glove box as they are more for your lights & stuff. Now these things are known to do in crank angle sensors all the time, so will it start when its cold? and not start after its warmed up? or just no go at all?? Crank angle sensor is MMMMMMMMMM i think its behind engine some where on bell housing!!!! i must check on that. And did it just stopped all together or was it a lead up to playing up OR what has been done to your jeep lately has any1 worked on it?? CHEERS HOPE IT HELPS.

i- bought it off a bloke who had it sitting in the garage for 6 months so no it hasnt had any work done.
-it just stopped on the highway, was no lead up and no problems before, and hasnt started since.

the car stopped because the return fuel line came off causing it to run out of fuel. and just wouldnt start after that, so wether that has anything to do with it ?
thanks for the help
