HELP! N14 Celect Plus shutting down...

I did send the ECM to Midwest ECM and they found nothing wrong. But it it might test OK while cold....That was before code 343 popped out for me. Looking for a loaner right now just to make sure. Thank you for your reply!

 

No problem. I trust what Midwest says. I have used them in the past.

 

I am not sure (without having my schematics which are at work) which harness the ignition power goes into on ECM. It could be lose of power from ignition to ECM. Just a thought.

 

I still think it's the ECM electrical overheating. Cooling plate?? Have no problems with fuel supply. Fuel is kinda cold in winter......

 

That could be but there is no reaction to road bumps, path holes, shakes, which i think should bring power loss.

 

Shut down solenoid may be having issues. But I believe your ECM is going bad. Mine would shut down for no reason and then start again. Then one day at the house when I was getting ready to leave it died and couldn't restart. The ecm finally died.

 

I think fuel solenoid should bring a code. But there are some exceptions everywhere....Thank you for your replay!

 

How long would it take to restart?

 

After what period of time it would restart back??? Mine takes from 1 to 30 minutes. thank you.

 

Sorry for the late reply. The shut down solenoid doesn't throw a code. Codes are only thrown by sensors. Mine would immediately start back up, but it was the ECM going out. Shut down solenoids are pretty cheap and easy to replace. They usually shut it down because they over heat so it just depends on how long it takes too cool down.
