Hello, I have been on every forum trying to find help but to no avail. Here is the problem, Truck will just shut off while driving ,pull over ,it may start back up or it might just crank but not turn all the way over, might have to sit five minutes or 30. Sometimes if I bang around it will start. I have replaced the crankshaft sensor, camshaft sensor, o2 sensors, cat, fuel pump, coil. It smells strongly of gas when this happens also. When it dies its not like when you are running out of gas its like it just shuts off. I have seen alot of other people describe a problem like this but no answers. I have wiggled pcm wires and every wire I can reach . Does anyone have any suggestions? Can a pcm be tested before buying one? I am at the end of ideas here.
