Hi my question is. I have been hereing several things. I would like to know for sure. Te other day I was out runing around and my Truch markes that it has a1/4 of a tank. Well it must have not been so. I was left stranded. I got more gas in truck. Went to start it and it would not start. I Tried till I killed the battery. To make a long story short. I got a new battery in truck and tried to start it again. It would crank but not start. I was informed that my truck might have some kind of a switch to reset the pump. Is this true. I would like to know if this is so I will do that and chec again. If not I will replace the pump. Please get back with me asap. Thank you very much.

It does not have a switch. That is called an Inertia switch and only used on Ford products. You need to use a fuel pressure gauge and verify power arriving at the pump during the first 2 seconds or during cranking.
This truck requires a minimum of 55 PSI to even run.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
