Hit a bump... stall

Recently put my 98 ZJ project on the road, twice in the last two months i noticed occasionally i would be driving and the dash icons and chimes would flash. But it stayed running and i went on my way.

Today, taking the Mrs to Dr after major surgery i hit a bump at redlight and it stalled.. although it would crank over it would not start. No dash icons, chimes, no four way flashers. Pushed it over to side of road, put in park, tried it again and it started with all indicators on dash lighting. 100 yards down the road it did it again.. coasted to stop on shoulder, put in park and started back up.

At the Dr's office i got under the hood, played with connectors.. particuarly at the ECU as i have read about this issue before... albeit slightly.

Drove home, with it only quickly happening once and it didnt seem to stall.. just dash indicators lit up like the two earlier times.

Am i on track with the ECU connectors or is there someplace else i need to spend time? I have a four hour drive coming up in two weeks and i need to know i have this fixed.

Appreciate any input guys... thank God this was able to continue on my way.. the Mrs couldn't have walked.

check/ clean all your grounds. pay special attention to the smaller of the 3 wires at your negative battery terminal.

Disconnect battery, pull PCM connectors and clean them with contact cleaner. Be sure all the locking tabs are there. If not use some heavy duty zip ties wrapped vertically around the back and over the connectors. Even better, get a large hose clamp that will go around the back and across all connectors horizontally, but be sure not to over tighten.

So glad you chimed in earlier today, saw your post and planned to check on it. On the way home in rush hour traffic it happened again and wouldnt restart, got it off the road and checked that ground. It was loose..

I had installed the Optima from my XJ, and some HD terminal ends from Wal-Mart. The wire from inner fenderwell pulled right out of the terminal end... apparently i never tightened it enough.. yeah i feel stupid. That wire is a bit short so i think i'll replace it..perhaps thats why it became loose.

Question: Both the black grounds were very warm, while the pos cable was cool?

I picked up contact cleaner and dilectric grease a few days ago, plan to do just that.


Thanks guys..

Increase the wire gauge/replace your grounds and power wires. Corrosion in the wires is probably your issue.
