Could be the boot on ur coil wire is cracked or the coil itself is cracked. Try new wire if not a repair might need a new coil. I don't know why it would keep turning over. I don't think its related to coil prob. Check ur starter solonoid..

1995 jeep wrangler changed plugs roter cap coil no power to coil can you help


why not the full story?
it ran ok, but misfires, so decided to do a real tune up, yes?
or is this a new engine, we can not guess context ,only you can say it.
no spark at coil? all spark plugs dead.
but i bet you dont know about ASD.
and takes 2 people to check spark
because 1 person can not turn the key and see spark by him self.
and it can only last for 3 seconds
so test 1 is no coil spark is.
check that the ASD pulls in. does it? if not fix that.
if it does, do you get spark for 3second then ends as ASD drops?
bingo fix that.
this page shows how all works, and to use the DTC errors for clues.
big clues.

What makes a 1988 F150 trucks ingnition stay engaged


Most likely the ignition switch or the rod in the steering column is sticking and keeping the switch engaged, possibly the ignition lock cylinder is sticky too. Easy to get lock cylinder out with a small punch that depresses a pin when the lock cylinder is in the run position, look under the steering column by the switch for a hole to poke the punch into and then pull out the lock cylinder.

1988 wrangler startup squeel and rough start


Sounds like you have a loose fan belt. May or not be related to the rough start though. Tighten (and, ideally replace) the fan belt.

1988 Jeep Wrangler starting problems. I replaced the ignition module, spark plug wires, coil, distributor module, and my jeep will not start. It gets fuel, turns over, but still not starting. It is a 1988...


you are saying it is getting spark, and fuel, right? If it is getting spark, and fuel in to the throttle body, check compression-make sure the Mass Air Flow sensor is plugged in, and double check your spark-you say you replaced all those ignition items, but do not say that you have spark.

Will not spark until ignition is turned off then moment ignition is is turned back it has one good spark


You didn't mention engine size so this isn't a fix (most of my diagrams are terrible anyhow) but, when you are turning the key on and off you are doing the same thing that the distributor pickup does (causing the coil field to collapse and make a spark) On that basis, I'd check the coil pickup and anything along that line ...also make sure that the run side of the ignition switch is hot with the key on.

Jeep want start


check your distributor cap. any type of moisture will cause it to turn over but it won't get the spark to the plugs
