Hey all,
'90 XJ 4.0 with starting issues, in that it won't.
The truck was sitting for a couple of years and was put back in service 4 months ago. I had a similar no-start issue back then, but cleaned up the cables and the ground and all was well - until last week. Out of the blue it won't start. Starter engaged (I can hear the gear click out) fuel pump starts, but the engine doesn't crank. I thought it might have been the battery (4 month old, but it was cheapo Autozone, so I figured it just didn't have enough ooomph anymore). Replaced the battery with Napa's best, still no crank.
It will start if I jump it from another car or from an emergency battery jumper I keep in the back.
Here's what I've done:
- Battery to starter, starter relay and block cables replaced with jeepers and creepers cables 4+ years ago. The pos end on the battery was a little gunky after the 2 year sit, but looks fine after cleanup.
- Added a 4ga cable from the firewall to the rear-most bolt on the fuel rail to enhance the braided strap ground.
- Replaced the starter 3 months ago. I thought it might be that, so I swaped in the orginal starter yesterday, no difference.
- After the engine was started, removed the pos cable from the battery, ran fine.
- Starter relay was replaced probably 4 years ago
I have another cable on the way to add an additional battery B- to fenderwell ground. I'll also replace the terminal ends with ends from 5-90.
I plan on doing some resistance and load testing on the cables today if I can, but wanted to get opinions here on what else I should be looking at. It's driving me a little nuts to say the least ...
thanks in advance -
