I have a 1995 f-150 5.8L 4x4 I think I am having fuel pump problems. The truck does not start all the time. The thing is it does it when its cold out and when it does not start I just shake my truck and then it starts up. I have replaced fuel filter, plugs wires, distributor, rotor button. when it does start it runs great. what else can I do? also would an egr problem have something to do with it.

 

check that fuel pressure. if you come up normal then your pump is fine. Someone correct me if i'm wrong but you should have between 38-45 PSI.

 

Well I replaced the fuel the pump and after a few days the truck started to not start again, so I asked my friends about the problem and they told me to replace the coolant temperature sensor and or the air charge temperature sensor. I know what everyone is thinking (Why would that have anything to do with it?) Well I changed the coolant temperature sensor and it runs great now, I am going to replace the air charge sensor as well since its only $13.
