Recently replaced Alternator, battery, and ECU. Now I can not get the truck to start. I have checked the coil and the spark plugs. I am getting spark at both places. The truck acts as though I am not getting fuel. Do I need to have the ecu reprogrammed.

I think so. If there is would that be a reason for the truck not starting?
