I just got done dropping my 350 back in again today and I want to start it up and it cranks fine but no fuel at all. I loosened the fuel like to verify delivery but the injectors just aren't firing. Then I checked for spark. What could it be?

When I checked for spark, there wasn't any.

 

Check all the fuses, even the one on the fender next to the battery. If the ecm doesn't get power you aren't going anywhere. A good way to check if the ecm is getting powered is to turn the key into the on position but don't start it. Listen for the fuel pump to prime. This feature is controlled by the ecm.

 

Well I'm almost postive the ECM is ok because the SES light is coming on with the key in the on position and the fuel pump is priming. I took the ignition module out and had it tested and that checked out ok. What else could it possibly be?
