Re: Mercruiser Inboard 350 Chevy
if it is wired correctly the fuel pump has to get power when the key is in the cranking position<br /><br /> after the key is in to the run positon the oil presure cut off switch should keep the pump running as long as there is oil pressure<br /><br />the only way to check is to connect a meter to the pump and see if it is loseing power or has power and just is not pumping<br /><br />i cant guess about the backfire it could be to many things with the fuel pump not working corrrectly it is hard to do anything until it works right<br /> <br /><br />tommays
