1 quick important question on GPR?

[zooterboy]

Should the GPR always kick on when you start your truck? I just put a new GPR on and it was working in the garage lastnight and so I checked it today and it didnt kick on, Now my truck is at normal temp, its just hardd to start.
I thought the GLow plugs always kicked on for at least a few seconds everytime you turned the key on even if the motor is warm.. Or does ot only kick on when the motor is cold..

Please any help on this..

ok i let the truck cool off for awhile and went out to check the dc amps, I get 40 amps out of the yellow wire going to the driver side and 55amps out of the brown wire going to the pass side glow plugs. Is this asign I have a few bad GP's? I read your suspose to pull about 20 amps per Gp? I guess I need to ohm the GP's and see if they ohm out right?

No it won't ALWAYS turn on. But usually will. Unless it's very hot.
Amps is nothing. Check voltage. Then go to the GP wires and check ohms.

I just did the test light test on the GP and 2 of them are bad. one on each side. So I guess I'll be ordering 8 new GP's. Im not going through the hassle of taking everything apart for just 2..

Thanks for your responce.

Test light? Use a real volt meter.

I did the volt meter, I just liked the test light test because it was quicker and easier to reach everything by myself.

Thanks for all the help.
