hey guys my glow plug controller was just turning on then off and so i replaced all my glow plugs with motorcraft glow plugs and know the wait to start light stays on for 10seconds and then blinks twice and i try to start the truck and it wont. So I shut it off and turn it on again and it stays on again for 10 seconds and doesn't blink and then starts right up. Is this normal or is there something else wrong with my glow plug system?

 

Thats interesting, and i have no idea why it wouldnt start right up, the flash or two after they glow, could be afterglow, i know our 92 will flash 2-3 times after the initial glow.

 

What year is your truck? There are two possible systems.

 

Its a 1991 f250 with the 7.3l
