hello everyone. i have a 1997 gmc suburban 1500 4x4 with a 6.5l diesel. drove it today and right when i pulled in my drive way i put it in park and the truck died. now when i try to start it it wont start and the glow plug light wont come on.
anyone help please.

thank you in advance.

Will it crank over at all?
Will the radio turn on?
Is all the power off?

have you tried to disconnect the batteries for 15 mins and then tried cranking? Sometimes letting the truck reset/recycle it will solve this problem
