Turn the ignition to the ON position and do not start the engine
Next you should hear the fuel pump run for 5 seconds
If not the engine oil pressure sensor needs to be replaced which has a circuit to the fuel pump to run it till the oil pressure is at normal operating range

I have changed my fuel pump about 6 months ago. But it was a used one. Anyway my truck started driving bad and my check engine light would blink on and off and at times would stay on. But it didn't...


You can have someone stand by the truck and they should hear the pump kick on when you turn the key in the on position. Can you spray fuel into the throttle body and will it start that will tell you if the ignition is ok or not and also tell you if you have fire to the cylinders. If it start right up and shuts off you either have a bad fuel filter, fuel pump or a plugged catalytic converter in the exhaust system.

HAVE A 96 ACURA TL 2.5 , WAS RUNNING FINE NOW IT HARDER TO START AND RUNS ONLY FOR MINUTES WHEN YOU PUSH THE GAS IT TURNS OFF. HOW CAN i TELL IF ITS THE FUEL PUMP OR RELAY SWITCH? PLEASE HELP


You will have to have a fuel pressure test done on the vehicle ,but it is either the fuel filter,or the fuel pump witch has gone out,it is not a relay,or fuse,or the pump would not work at all.Replace the fuel filter and see if the engine performs correctly .If the fuel filter helps,but the engine still runs poorly,replace the fuel pump,if the fuel filter went to long,being restricted,it will wear out the fuel pump.

How do you check to see if fuel pump went bad on 2004 Nissan Tita


Careful doing this. Disconnect the fuel filter line between the tank and the filter. Have a bucket or equivalent below to catch incomimg gasoline pouring out. Have some one turn the ignition key to on. Do Not Try and turn the key to START!! Just turn the key to the ON position. This will kick in the oil switch to feed gas to the engine for 5 seconds. If gas comes out the pump works. Reconnect the filter and try again. If no start is happening still disconnect the fuel filter's line towards the front of the engine this time. Turn the key ON. If gas comes out the filter is fine. If not the filter is clogged up fully

Fuel and starting


if the pump is known to be good, check the fuel filter. the fuel filter may have never been changed and this may very well be the reason why the pump went out in the first place. hope this helps... visit again and rank this answer if I helped thanks!

Are you certain that the fuel filter isn't bad and leaking gasoline?

There is a cheap plastic locking mechanism holding the fuel filter inline with the outlet side of the filter. Mine went bad and started leaking fuel everywhere i went. Especially when I was stopped at a light for a long period of time. A cheap tool can be bought at any automotive parts store to remove the old filter , you will need the tool to install a new filter.

If the filter is okay then I would just disregard my post.
thank you

Tahoe will not start new fuel pump/w/filter


BE WARNED!!! i was a GM mechanic for years, i personally found out for myself, that many if those pumps bought from parts stores auto zone, orielly's, napa, etc... have the possibility of being bad from the factory, i once worked on a 98 silverado, the customer had replaced the pump 3 times with an auto zone pump, every time the pump would either not even start the truck or it would loose pressure within a week or two. after we installed a new GM pump he no longer had an issue, sometimes its worth it to pay a little bit more and buy a pump from a dealer, plus if you buy a GM part, it comes with a 5 year 100,000 mile warranty, even if you buy it over the counter and install it yourself.
