question on module

[ricbob]

I have had tthis stalling problem i have asked about before.98 gmc 1 ton Starts and runs for a couple minutes then just quits. wil not start again unless i turn off the key for a few seconds. if i turn the key off then back on immediately the glow plug light wil not come on and i believe it seems to not come on at all until the key is turned off for a few. it will then start right back up and run for a while again. It seems to get better the warmer it gets. Last summer it ran fine after it was warm. My question is,,,, does this part about running better in warm weather preclude the module from being the problem, as heat seems to make them fail?.

Stalling is usually caused by a failing PMD (BLACK BOX ON INJECTION PUMP)

Just a suggestion, but you already have a thread going on this topic with some good responses already - it would probably be best if you stopped using this thread and continued with your other one. I did add a comment to your other thread that might help... or it might not!:)
