i am still having a little trouble starting my truck, especially in the mornings ! i changed the plugs, the plug wires, cap and rotor ! i changed the fuel filter and my nephew ran a test on the fuel pump and it,s holding good pressure ! he unhooked the regulator when it was running and the needle started to fall off some, he hooked it back up and it started to climb again and no gas in the vacuum hose so the regulator is working good, right ? the only thing between me and him is that he showed me on a old fuel pump he had there is a filter on the pump and he said it might be starting to clog up ! i ran a bottle of good complete fuel system through it and helped it some ! should i run another bottle through it again ? thanks guys !
