My 94 gc cranks but won't start. The only trouble code retrieved from he computer is 55. There in no spark at the plugs, but there is spark at the coil. The computer has been tested and it appears okay. I've replaced the cap and rotor with the same results. I think that the timing is off. Any Ideas??????!!!!!!!

HI. IF YOU HAVE SPARK THEN THE CAMSHAFT SENSOR INSIDE THE DISTRIBUTOR MAY BE GONE OUT $50 DALE
jeepman600@aol.com :smokin:

your getting spark from the coil, so the only issue is delivery. remove the distributor cap, is the rotor moving when the engine is cranked? if so replace the cap rotor and wires, most of the time this problem is caused by washing the engine or running thru a puddle of water, and the igniton gets wet. once a carbon trail is formed by the spark, it is unlikely that you will ever be able to intrupt it by cleaning it. if this doesn't fix it, the timing chain may have jumped (cam crank timing issue, back fires in intake or exhast). otherwise (if its not turning) the cam shaft could be broken, the pin that holds the gear on the distributor shaft could be gone or......an alien stole your camshaft.....

I changed the cam sensor (stator) and have the same problem spark at the coil but not at the plugs. I checked the timing chain and it has not slipped. I have changed the crank sensor about 5,000 miles ago. I'm not sure what to check next.

Agian it is a delivey issue, the only thing left is to get the spark from the coil to the distributor cap across the rotor and back to the rotor cap, then down the wire to the plug. the only things left if the rotor is turning, is the coil wire, the distibutor cap and the rotor. Nothing else can cause the problem.

In the dark, crank the engine, look at the coil, wires and cap, are there sparks? that where the problen is.

Hi, how long has it been since you changed coil and plug wires, if you have spark at the coil and going into the distributor cap, are you sure you got the wires on right, plus check to see if the cap is mounted right on distributor. firing order is 1-5-3--6-2-4 going clockwise, number 1 is the first hole past the hold down bolt , the holddown bolts are positioned at about 5 o'clock and 11 o'clock positions. look on the cap #1 is usually marked on cap with a number 1 hope this helps DALE

the wires are all plugged in right - the damn car still won't start - if anyone has any other ideas please please help!! i have changed the rotor dist cap , cam sensor, crank sensor, coil , and plugs AND computer has been checked i am out of ideas.

I dont see wires among the things you changed. you say you have spark at the coil.. its not running down the side of the coil to one of the terminals is it? if so repalce your wires and the coil, the wires causing the bad trail and the coil bad from the wires.

HI NOT TO BE A SMART A--, BUT DIDYOU MAKE SURE YOU GOT THE RIGHT ROTOR AND DID YOU MAKE SURE ITS SET IN THE NOTCH ON DISTRIBUTOR SHAFT. JUST A THOUGHT DALE

HI ONE QUESTION DOES YOUR IGNITION KEY HAVE A SMALL CHIP MOLED IN IT, DALE jeepman600@aol.com :smokin:

Okay now the coil is producing no spark, or an occasional weak spark. Sometimes it still works fine. I accidentally grabbed one of the spark plug wires and got zapped. I thought this was unusual because I there is no visible spark. WHATS GOING ON?

HI, YOU STILL COULD HAVE A BAD CRANKSHAFT SENSOR I GOT ONE AND HAD TO CHANGE IT 4 DAYS LATER. IF YOU ARE GETTING GOOD SPARK IT WILL JUMP A 1 IN. GAP DALE jeepman600@aol.com

The spark would never reach over an 1/4 of an inch

That Isn't Much Gap For Electronic Ignition Have You Changed The Plug Wires Dale

Yes I've changed plug wires- could it be the coil?

HI YES THE COIL COULD BE BAD AND NOT STRONG ENOUGH TO FIRE UNDER COMPRESSION DALE jeepman600@aol.com :smokin:

Gee it would sure be nice if you would reply directly to our resonses. Does the distibutor move when cranked? did you replace the coil wire? did you try cranking the engine in the dark? If you want to use these forums then you have to tells use what you did. Yes a coil could cause it but if you had read and followed my instuctions then you would know that. do the work, we are leading you to the problem!

A Frustrated LEo!

Yes the distributer moves when cranked. Yes I replaced the coil wire and a the spark plug wires. I tried cranking the engine in the dark. No spark at spark plugs and intermittent spark at coil. Sorry for not replying to your tips. Your help is greatly appreciated

remove the high tension wire from the coil, look for any sign of a trail that leads down the side of the coil, it might look like a pencil mark or a crack. if there is one that is definatly the problem

HI DID YOU LOOK INSIDE THE CAP TO SEE IF THERE IS ANY CARBON TRACKING, DID YOU CHANGE THE COIL WIRE, COULD HAVE A HAIR LINE CRACK AND ITS SHORTING OUT TO WIRE TOWER DALE

I replaced the coil, but the jeep still will not start.

HI JUST A THOUGHT LOOK IN THE POWER CONTROL BOX BEHIND BATTERY TO SEE IF YOU HAVE ANY BLOWN FUSE. HAD ONE THAT HAD BLOWN FUSE FOR THE ASD, 97 HAS 3 ON THE ASD. JUST A THOUGHT DALE jeepman600@aol.com

Problem solved. Turns out it was the coil after all. I put the distributer in 180 off after installing the camshaft position sensor. But now I have a new problem after driving for about 5 minutes the check engine light comes on. I retreived code 51- engine to lean. I live in colorado at about 8000 feet. when I had the computer tested is it possible they installed fuel metering for sea level and now my engine is getting to much 02 because of the computer?

My 2004 GC Jeep died today and I have noticed that my "30 Amp - A9 fuse - Engine Control) was blown. It turns over but it can't start. I have checked all the abvious, plugs, etc. No spark.
I appreciate anyones help.

HI, IF YOU REPLACE THE FUSE DOES IT BLOW THE FUSE RIGHT AWAY. YOU'RE TALKING ABOUT IN THE POWER BOX BEHIND BATTERY
DO YOU MEAN A SMALL FUSE OR A MAXI FUSE. DONT HAVE 2004 DIAGRAM BUT IF YOU CAN GIVE ME ANY INFO. I'LL TRY TO HELP YOU OUT DID YOU CHECK ALL THE FUSES. GIVE A HOLLER AT---jeepman600@aol.com DALE

tim. replace O2 sensors
