Lately my 90 xj once and a while wont start. I can leave it and come back later and it will start. This is a difficult problem for me because it isn't always a problem so I am afraid one day it just wont start when I am in the bush.
When i turn the key I the engine turns over no problem and the starter is working just fine. The problem is I am not getting any sort of firing
I can also hear the fuel pump engage when I turn the key as well
the last time it happened I was at a friends and we started trying to figure it out. I thought maybe there was no spark at first, so I checked the coil, cleaned the cap and rotor checked to see if there was a spark, everything checked out to the distributor cap.
I then pulled my return line off my fuel pump to make sure fuel was there, a little fuel puked out so I reconnected the quick disconnect.
I then pulled a wire off of a spark plug turned the engine over agian to check power through the wire then with the wire off of one of my spark plugs the engine randomly started again, along with some fuel puking out of my return line because I wrecked the O ring in there. Fuel wasn't puking out before when I turned it over after I pulled the quick disconnect so the sudden rush of fuel made me think it could be a fuel problem again but I recently replaced the fuel filter and pump and don't think it could be the pressure regulater valve but I could be wrong.
So that is as far as I have gotten, any ideas would be appreciated. Hopefully it isn't an electrical problem.
