2006 jeep commander will crank but wont start

[Addie]

Ok, I am having a run around situation with my jeep commander. It's a 2006 4.7 v8.
It will crank but wont start.
What has been done....
Replaced the TPS
Replaced the ECM
Have checked all fuses

My fuel pump still primes, when it was taken to the jeep dealer they said the TPS was stuck open in high and adjusted it. Sent me on my way and then it died again.

So it has been, struggling to start, before this it started but quit running in the middle of driving.

Have taken it to two mechanics and a jeep dealership. It's not throwing any codes and no one can tell me what's wrong.

Has any one ever seen this issue and is there something else I can try?

Thanks
Addie

On tj jk and wj... the CKP crank sensor on the bell-housing goes bad. You usually don’t get a CEL code.
Only use OEM and be sure the paper gasket is on the tip when installing. That is a spacer that keeps the CKP from getting damaged from rubbing the flywheel.
