Sometimes they will go out like a lightbulb, other times they will try to hang on. The best way to test is get a fuel pressure test done.



The fuel filter can clogged very fast if you pumped bad gas into your tank.How to trouble shoot fuel pump 1993 altima, fuel system extremely rough, will a pump go out completely?

yes they can go without any warning but sometimes it,s not the pump but the fuel filter.some people just think it,s the pump when it don,t start but the fuel filter can act like the pump when it gets clogged. the filter can get pretty clogged that gas can,t go through them. also your problem could be the pump regulator on the fuel rail.
