2002 Pontiac Montana Repair Question
Mileage: 140,000 miles.
My 2002 Pontiac Montana sometimes won't start?
Answer
Are there aney pcm codes. If yes what are thay. We need to know if we are having a spark or fuel. Problem. Check fuel pressure check spark @ the plug on 2 wires. Let me know how you make out.
There are no codes, fuel pressure is 50 psi, checked spark on the front three plugs and I have spark on all three.
Is this what you have when its not starting ?
When it is not running I still have spark and 50 psi fuel pressure.
are injectors working when no start happens?
You mentioned there is inject or pulse but not if there is spark on the front 3 when not starting. Check this and get back to me
noid light is usual test. you can buy or make your own. someone mentioned harbor freight has set for $10
Don't understand what you mean djcl. fixitmr could a bad signal or short for the pcm be intermitant. I'm thinking it might be the injectors because the last time I had a no start I tried to get it started until the battery died and when I took the front plugs out they were dry as mummy dust. You would think after trying for so long they would be wet. Do you agree?
yes, i would expect them to show wet condition. intermittant no signal/short sounds right.
