Starting questions

[mitak1]

I have a 96 F350 PSD. Is it better to start the truck immediately after the wait to start light goes out? Or does the GPR continue warming the plugs after the light goes out? Also, in cold starting situations, is it best to just keep cranking the motor over until it starts, or try to start it in bursts, cycling the key off then on in between to re-engage the GPR? Thanks!

Yes the GP's stay on after the wait to start light goes out. They also cycle on and off for a couple minutes after the motor has started. Depending on the condition of your motor (i.e. compresion) and glow plugs you might have to wait up to a minute after the wait to start light goes out before it will fire. Most definetly you want to try starting in bursts (no longer than 30 sec) to keep from frying the starter. After sitting all day at work without being plugged in I will turn the key to on and wait 30-45 after the light goes out before I start cranking on it and will fire right up.

Thankyou very much for that info.
