Hey all. I think i did it this time. I was changing out my nun3 ecu for nun1. Unhooked the positive cable, unbolted ecu pulged nun1 in, hooked positive back up, and turned key. My cooling fan came on and i can't hear my fuel pump. Cranks but no fuel. Done lots of searching but can't seem to find out what the problem is. I should've waited for the weekend. Any ideas?? need the car for work

I also tried putting the old (nun3) cpu back and I get the same issue.

I'm not trying to insult your intelligence but did you check your fuses maybe even emergency cut off switch.

ya i was just out checking those...cant seem to find the fuel cut off also the strange thing is that the cooling fan is coming on now as soon as the key is turned to the "on" position.

well...made a panick call to Fraser Ford. Al there is great when it comes to 'tours...probably great when it comes to all their cars/trucks. Anyway, he let me know excatly where the ground wires were that applied to the pcm and which to check first. Found the bad ground i messed when i pulled the pcm and its all fixed now, running the NUN3, I reckon i'll have to go try the NUN1 now, with the new ground...(guess i didnt learn my lesson of not touching things eh?)
