Customer Question

Here...I have a 2002 Pontiac Montana that stalls while driving. It will restart after several attempts. Crank sensor and fuel pump are new...any suggestions
JA: Thanks. Can you give me any more details about your issue?
Customer: Ok...vehicle starts and runs fine. After a mile or so of driving the vehicle will stumble, recover and run ok for the drive back to the shop. Next test drive, after a mile or so it will stall completely then restart after several attempts. It has the 3.4 engine in it
JA: OK got it. Last thing — Pontiac Mechanics generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Have you noticed if the check engine light on when it wont start?

Customer: replied 1 year ago.
No check engine light. No codes in history or current. Other than the stalling issue, vehicle runs FINE. Also cut the cat.convertor to eliminate that (problem) Re welded unit after no change.

OK. My question was does the check engine light illuminate when it stalls

Customer: replied 1 year ago. check engine light
Expert:  Tool Hut replied 1 year ago.
If the check engine light does not illuminate when it stalls it is an indication of a power loss to PCM or a bad PCM
Expert:  Tool Hut replied 1 year ago.
When it stalls the light should come on.
Customer: replied 1 year ago.
I am fairly certain that's it's not the PCM...but thanks anyway

I don't think you understand the question. When the engine stalls the check engine light should come on.
