I Have replaced the fuel pump 2 times just to make sure its good, fuel filter, ignition module, map sensor, coil, rebuilt TBI. The weird part is, it will start just fine after I pop the hose off of the fuel line down by the filter. It will start a few times in a row like that. After about 5 starts it will stop working. It will just keep cranking and the injectors will only shoot 1 or 2 sprays of gas and then stop. But If I again pop the hose off and let the gas run out of the hose and reconnect it, the injectors will pump continuously and the truck will fire right back up. Could really use the help. Thanks in advance for any replies.
