93 jep grand cherokee spark issues

I have a 93 jeep grand cherokee , it stalled on me the other day , I checked for spark and there was none , I replaced the cam sensor / pick up coil . I also replaced the crank sensor , I got a very faint spark then . so I replaced the coil ,which looked fairly new when I bought the vehicle in April , then I got good spark . My wife drove it for 1 day then it died again , checked for spark, and it was faint again , I replaced the coil again and now it runs ok , could this be the ecu ,there was no engine light that came on. I have no way of checking it and really didnt want to take it to a dealer , any ideas would be appriciated thanks

Just a thought you might want to check the plug that connects the coil to the wiring loom .......maybe some corrosion .

My 1997 grand Cherokee start and off what should I do


i guess, you meant , engine issues, engine cranks ok , starts then stalls right?
that is cause (most times) by the ASD relay dropping out.
is it? dropping just before the stall?
if yes, the scan tool will tell you why, there are 8 reasons...
all documented in all jeep 93+ FSM books.

does car have Immobilizer option?
if yes, that too will drop the ASD so (bad boys) cant steal it.
so if the immo light (generic name) is on or flashes before cranking or during cranking, then the IMMO is UNHAPPY.
again scan it.
if yes, IMMO did you try both key fobs, as came with new car?

http://www.fixkick.com/Jeeps/ASD.html

if the ASD does not drop.
the that can be 50 reasons... a huge list.
major engine parts.
never had a REAL tuneup in a decade? (spark bad)
lost spark
bad engine.
bad fueling (too much flooding or too weak or none)

if engine floods?, crank with wide open throttle per operators guide.

I have a 1997 jeep grand cherokee with automatic and 4.0 six cyl engine--it drives great for a day or two then stalls out seemingly for no reason--now tonight it has no spark from the coil--so I feel it is...


Unlikely that it's a computer. Check your coil and the grounds, make sure you don't have any breaks in the wires that could cause an intermittent problem.

93 Jeep Grand Cherokee Won't start


The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.

1993 JEEP GRAND CHEROKEE LAREDO- TRUCK WONT


OK...I have a 93 outside...one diagram I have shows an ignition module next to coil...but there is none on mine, (4.0 engine)
Two items to check are crank sensor and cam sensor inside distributor. Test procedure can be found in just about any manual including haynes.
You will need a decent volt/ohm meter to do testing. You can also check codes by turning ignition switch on/off three times, leaving it on the third time. Check engine will flash code #'s (ex: one flash, pause two flashes= the number twelve.then followed by a longer pause then another set of flashes etc.)

Jeep won't start


Check voltage at coil. Check coil output (spark should be healthy even at 1/4" away from ground). If OK, then change module The only testing on module is with a special tool. Therefore if contacts are clean, that's all you can do with it!
