I guy's really need help here .I have 95 4.0 >I have replace the head gasket and manifold gasket as well. I put everything together again and now not getting fire form coil or plug's.I replace plug's -wire's and coil and cap and router cap .This was running before I replaced the gasket's as well. I checked the fuse's and relays they all getting power .but did not check the crank sensor yet got dark on me.but like i said was running before break down to change the head gasket

 

this happens. obviusly somehting happend in the process. its usually a connector forgotten, or a wire pinched. retrace your steps. check for connectors that aren't plugged in, or wires pinched. let us know how it goes.

 

OK find that the wire to crank shaft senor pulled off .should that fix my problem?everything else looks good. my dad pull little hard when hold the intake so that's what pulled it out

 

that will do it

 

Sure did thanks .also have other Q: need A: my other 2000 jeep cheer 4.0 with EC ever thing .coil pack rail . ok start off fine this morning when I stopped to get something at store when restart with gas in tank it begin to run roof like misfiring but just had it tuneup just like mo. ago its gap right at the plugs .o ALSO the oil presser drop to 10 but had oil change last week. any though

 

jeeze, who's workin on your junk? first thing to check is what plugs are in it. jeeps only like the o.e. plugs. the older 4.0 was champion, the newer one wants the ngk plug that came from the factory. oil pressure can be just a sender, they tend to get damaged at quick lubes when they have to wrench off the filter that was put on too tight.

 

well me working on my junk .but the oil change. I put the good plugs and new boots and springs on. the senor was thinking was going bad or they missed with it . u think have to replace the rail pack or the descriptor sorry if not spelled right .that why i hate EC"s on car's or truck's
