Hello, I am new to the forum and would like some advice concerning my 2001 F350 7.3 diesel truck. I have been having a few problems with it.

1st) The truck seems that it needs to be plugged in, in order to start even when it is 35-40 degrees out. Is this normal?

2nd) when I put the key in the ignition, turn and wait for the warm up, then try to start, it cranks hard, then the wierd part is, that when I pull the key out of the ignition the truck will continue to crank and try to start. Is this a ignition problem, or relay, or something else?

any help or advice on what to do would be greatly appreciated. Thanks, Grant

 

Have you checked your glow plugs?

the GP or GPR is bad.
when are you pulling the key?
how old is the oil?
