    Ok here is the problem I got an 87 burban with a 6.2 in it! I had it plugged in for about 30 mins the temp was about 11 out! I went out to see if we had enough to push check my lots and whatnot! when I tried to start it it cranked but didn't fire and my glow plug light wouldn't come on! At first I thought it was just the light but nope didn't fly!
    I then used an old trick I used when I repo semi's in 40 below weather I took a hair dryer and stuck it in the intake within 30 seconds I was off and running! As soon as it started the light for the glow plugs came on! I am thinking of doing My usual trick and bypass the computer by putting a push button on the solenoid!
    Does any one know how long would be too long to hold the button in and glow plugs on at one cycle!
    My 5.7 GM's I know can take 7 seconds also my 6.9 and 7.3 fords can take 7 seconds! I found that out by taking them out and testing them!

    Don't mean to tout another board but check the link below. There is a section on the 6.2's (non-turbo). They gave me a lot of help on my 82 6.2 and there is a lot of posts about glow plugs. There are plugs available that will burn a lot longer than 7 seconds without burning out. I have a manual setup on my 6.2 and you don't have to hold them for many seconds all at once. Cycle them. Burn for 7-8 secs then off for a few seconds and then on again. That's what the controlers do as I understand.

    I have had diesals for years and it's usually all or nothing problems limited to the following big ticket items: glow plugs, injectors or the dreaded injector pump.
