1997 GMC Suburban fuel problems need help!!

[footer77]

I have this 97 suburban, i have replaced the fuel pump,fuel filter, and fuel pump relay.... but i get nothing. So i took my test light and checked the wire harness and i replaced that too.... well i go to start the beast and it turns and that's it????? what could it be? well i checked all the fuses.... or did i miss any more?? what could it be?

i also talked to my mech. he said to check all the fuses and he said the wire harness was probably bad too, but i changed that when i replaced the fuel pump??? so what the hell could it be???

Remove and have your ICM tested at Auto Zone or Parts source before replacing it. The ICM on the bracket right next to the coil on the Vortec engined trucks like your '97.

Here is a link to the coil and the ICM just to the right of the coil. Good luck and keep us posted. http://econtent.autozone.com:24991/...00c152/80/08/ee/04/small/0900c1528008ee04.jpg
