Won’t start by key , roll start works fine


Recommended Posts

1999 Cummins 24 valve , quadzilla , 100hp injectors, nv4500, air dog 150

 

when I try to start my truck with key half the time it will fire right up other half it will turn over for ever and won’t go .

 

dont believe it’s a prime problem as I checked for leaks and made sure everything was tight , you can turn truck off for half a second and try to start , just turns over 

 

but if I roll start it , it fires right up no problem ??????? 
 

cleaned all batt cable ends ,and grounds 


help please it’s geting annoying

ignition issue on the column?

 

have you tried putting the key in run, use a wrench and jumps the poles on the starter to see if its not the starter? if jumping poles on the starter works, its something between the key ignition and starter, possibly a relay?

There is a starter solenoid fuse in the PDC. There is a starter solenoid relay in the PDC

 

Then when in the start position the key switch should be giving power to the ECM, PCM and VP44

 

See the switch with the light blue lead than is the lead back into to the dash fuse panel for fuse 11.
