ok I just bought a 1990 XJ laredo w/165kmiles about a month ago...
I have a crank but no start situation.
I changed the Crank sensor (major PITA I thought Jeeps were easy to work on)
I also changed the fuel pump relay...when the Jeep is running it runs awesome so I do not believe this is a fuel pump issue...
However here is the problem...I hear the fuel pump priming about once every 10 attempts to start the truck.
When I do hear the fuel pump prime...the truck starts well and I can drive it for hours without problem...if I stop the truck and restart it right away...no prob...if it sits for more then 15 minutes...it dies...
Another thing I just noticed, when I turn the key to the RUN position (just before starting the jeep) and hear the fuel pump, my headlights usually come on and I see my seatbelt sign on the dash. Now when the fuel pump doesnt prime, the seatbelt sign doesnt come ON nor my headlights. I have no check engine light and I have never seen another light coming on then the seatbelt one..
I'm starting to believe the computer is going bad, what do you guys think? I found one on ebay and I'd like to see what you guys think before ordering it.
Thanks
