I’m trying to get my 1992 YJ road ready for my daughter. It has been a couple of years since it was on the road. I have gotten her running after changing the fuel injectors, the fuel pump, this kept her running for about a week then I lost fuel pressure in the fuel rail and had no spark. I then replaced the crank position sensor, the throttle position sensor, the coil, the distributor cap, the spark plugs and wires. Still no luck, until I left the key in the on position for about twenty minutes when I hear the shut down and the fuel relay start clicking. I turned off the key and then tried to start it and she did finally fire but would not stay running.
The boss on the distributor was cut off about 10 years ago by a former friend I had work on it the last time I had an issue with her running (big mistake ever letting him touch my ride). I adjusted the distributor a few times and finally got her to run. After she warmed up she started to spit and sputter, so I repositioned the distributor again until she smoothed out. I was then able to drive her for hours with not issue. I could shut her off and she’d start right back up.
However the next day again I had nothing, I also noticed that neither my “Check Engine” nor my “Maintenance Required” light come on when I turn the key or try to start her. I replaced the relays and still noting. I added two more grounding cables on to the motor and one to the body. Still have to leave the key in the on position until the relays start to tick at which time the “Maintenance Required” lights will flicker in sync with the relays ticking. Again I had to reposition the distributor to get her to stay running and reposition after she warms up.
I thought maybe I have a bad contact at the ECM so I removed the unit cleaned the contacts and greased them again, I also did the same thing to the fuse block connections at the firewall since I was already there. Issue still remains.
I am thinking about replacing the distributer in hopes of curing the repositioning issue, but I am at a loss as to what to do to about the 20 minute wait until the relays tick. Any help would be appreciated, thanks.
