Last week I was coming home from work and stopped for gas, when I went to leave the truck would not start. Checked and had no fuel pressure. Yesterday installed new pump. Truck still will not start, checked and have no power going to the pump. Checked all the relays and fuses and all are ok.

 

Have you checked the inertia switch?

 

Yes, it is ok. My brother thinks it is the PCM

 

Replaced the PCM yesterday and it starts but when I drove it for a few miles it starts to sputter and stalls.

 

Did you check all your vacuum lines?
