Turn key forward and listen for the fuel pump to kick on. It will make a high pitched sound then shut off. If no sound the more than likely you need a fuel pump. You can check at the fuel rail with a guage pressure should be 30psi.

Can't find fuel shut off 1999 i3o infinity


Only Ford products have an enertia switch for the fuel pump.
You'll need to figure out if the pump has power or not from the pump relay when it stops running. Then go from there.
It could be ignition or something else besides fuel.

Have 1999 nissan qust runs fine when started but if you drive very far. it starts chugging and running rough. doesnt seem to get hot. but doesnt run well at all.


First check fuel pressure with engine cold, and hot at engine side of fuel filter. There shouldn't be any difference. If you get a significant pressure drop after running engine until warmed up, replace fuel filter and check results again. If that still doesn't help your fuel pump might be on the blink. This is assuming your car is in good tune(plugs,wires).

1993 Infiniti J30 no fire to fuel pump


Is the key you had made an official replacement. Some keys have a chip built into them that activate/deactivate the security system. Typically these come from the dealer because they need programmed with your VIN number. The car thinks its being stolen so it doesnt send power to the fuel pump.

1999 oldsmobile bravada stalls out when driving and will not start at all times have had starter and alternator checked


If its a crank but no start, i would put money on it that it is your fuel pump, ive put two in my 1999 bravada, they have updated fuel injectors too (recomended), i changed injectors all the way to the pump fully new fuel system and it runs just fine now. go to ur local junk yard and pay about 50 bucks for a used one and see it if doesnt help... i would recommend trying a used one befor u spend 300 on a new one. good luck

Grand cherokee 1999


1. is the engine turning over. If it is then you probably have a timing/fuel problem.

2. If all you get is a click sound and no engine turn over then flat battery could be a starting point.

3.if it starts and runs rough plugs and or plug leads may need looking at. Or maybe fuel injection system.

4.Not enough information to get more specific.
