It will crank, turn over but not fire. It seems when the battery is at full charge it starts up fine, although I'm not convinced the battery is the problem. I've changed the CPS, so thats not it. I changed the spark plugs and checked for spark, and that was good, so I figured fuel issues. I also checked the distributor and the cap and rotor looked great, cleaned it out nonetheless, along with cleaning all my connectors and relays with some canned air and dielectric grease. I changed the fuel filter and it seemed to be fine for about 10 minutes of running perfectly, only to die while driving, and not starting back up. I thought it might be the ballast resistor issue that is common, so I jumpered the two wires and nothing changed. I'm convinced I have a bad fuel pump because, as far as I'm aware, its never been changed out, although it could be my coil, which I haven't checked yet.
ALSO, I'm pretty sure I have a short somewhere because I have to charge my battery everytime I work on my XJ, because after I let it sit for a few days and try to start it up, the battery is completely dead.
What do you guys think? I need to get this heep runnin' again!
TIA,
