Hi first time on here. So my truck will start then abruptly shut off i after about 3 seconds and prime is completely lost. Also having to put a boost pack on constantly . Could it be an electrical conection any ideas would be appreciated?

 

disconnect your batts put them on full charge for at least 4 hrs.....then load test each batt or have them load tested at local autozone or advance auto parts for free....if no good replace both with brand new if one test good still replace both good rule of thumb...loosing prime check bottom of fuel filter called wif senser ..{water in fuel} for leaks...pump the primer up till rock hard look down and see if wif senser is leaking..if so you can replace it with metal with drain **** so it wont leak...scott
