No spark

My 1992 Jeep YJ 2.5L will not start. I checked for spark and the plugs and there is none. I also took a test light and checked for power before and after the coil while cranking the engine and there is none there either.

I tried to use the check engine light to get some codes but the light doesn't even come on. As well I cannot hear the fuel pump cycle when the key is first turned on.

I was told by this forum to take the computer apart and check to see if there is anything there and I never noticed anything besides minor corrosion on top of one of the compactors. I mean like maybe 35% covered.

I cant get a mechanic to come take a look at it so I am stuck figuring this one out on my own.

Any help would be great!

Thanks a lot.

I was going down the road and my jeep died on the spot. I had no spark and no code light. My fuel pump would not kick on when I turned the key. I replaced the cam position sensor in the distributor and the crankshaft position sensor on the bell housing. I still had no luck. It turned out to be a corroded ground wire to the computer. I hope that fixes you up.

Due to recent budget cuts, high unemployment and the rising costs of food, electricity, gas and oil, as well as current market conditions, and the overall state of the union, The Light at the End of the Tunnel has been turned off. We apologize for the inconvenience.
