YJ No Spark
ok people, it's a 95 YJ, 4 cyl., 5 speed.
No spark. I replaced the distributor, the cap & rotor, wires, plugs, and coil. No spark. When I had my wife crank the engine I noticed a spark from the starter, or thereabouts down there. Any ideas? |

it also could be the timing chain.

Interesting. Now, I was having trouble before it died, and one morning I
went to the jeep and found the key in the on position, heater fan blowing. Would juice through the ignition wires overnight hasten its demise?? "L.W.

Nope, the CPS doesn't have any current flowing through it unless the
engine is running... and then that current is self-generated. Jerry Dave Lee wrote: > Interesting.

ok, makes sense. Perhaps it just died for good then. I remember my Dakota
losing the crank and cam sensor, twice. I'll check that next.

Hold the coil lead by the block and see if it draws a spark when you turn the engine. Double check you put the rotor in there. And the camshaft position sensor pickup on the distributor is hooked back up. And the plugs are going to the proper post. -- DougW |

No spark at plug, nor coil. Rotor in place, brand new distributor and
connected. Funny, after a while I did open the cap up just to double check the rotor. You never know. Well, hopefully tomorrow I will attempt the crank sensor. Any idea why I see a spark at the starter? My wife hits the ignition and 2 out of 3 times I see a quick little spark down there.

Your seeing the solinoid close, it's basically a big ass relay and will spark. Could be the coil. but before going there, double check the harnesses around where you were working. Sometimes things come loose. You can take a noid light (12V lamp) or multimeter and measure across the coil primary (small side) while starting the engine. You should see 12V pulses If you do then the coil is shot. -- DougW |
