The fuel pump works off the engines oil pressure switch upon first starting the engine. That switch makes the fuel pump prime for the 5 seconds as well
When the engine reaches the normal oil pressure the computer shuts that circuit off and turns the fuel pu,p relay circuit on to have the fuel pump to run until you shut off the engine

2001 ford windstar, van has been setting for a year, got my license back and went to start the van, no fuel pump noise, replaced fuel pump, started just fine drove it around for a day parked it now wo


Can you hear the fuel pump run, if not it may have failed again. I have seen new fuel pumps last a day or two and then fail. If your pump is working then replace the fuel filter. Anytime you open the fuel system, you should replace the filter.

I HAVE A 1986 GMC VANDURA 3500 CARGO VAN,ALWAYS TURNS ON WITH NO PROBLEM,OK HERES THE THING.MY GAS METER WENT OUT RECENTLY SO I DROVE IT AROUND ALL WEEK BASICLY JUST TRYING TO EMPTY THE TANK SO I CAN FILL...


If the fuel level is very low and the van is not level it's not going to start even if the pump is good.
When you turn the key to on you should hear a fuel pump noise for 2 to 3 seconds if the key has been off for at least 10 seconds,and when cranking or the engine is running the pump runs because there's oil pressure sending power to the pump.
Have someone listen back at the tank.No Noise?then it might be time for a fuel pump.
Your fuel filter may be just ahead of the rear axle on the passenger side under the van.
But.....if your gas gauge went out and now your pump quit,maybe the wiring back at the tank is corroded?

My 1995 Buick Park Avenue stalled on the highway going 70-it did not restart. I thought that maybe my fuel gauge was broken, as it acted like it had run out of gas. It just keeps cranking and cranking but...


sounds like the fire is good, you might try replacing your fuel filter first and if it still has the problem then the fuel pump, do you hear the fuel pump whirring when you turn the key on? thats what the sound is that you hear when first starting the car, it will whirrr and then click letting you know it has proper fuel pressure

2000 silverado wont start


one good way to check that the fuel pump is running to listen. take the gas cap of and put you ear the the fuel tank fill neck. have a freind turn the key from the off position to the on position, but do not start the crank the engine over. you should hear a huming or wizzing sound for a few short moments. if you hear that sound the pump is running and more thatn likely pumping fuel.

Engine would not accelerate, now wont start


Sounds like the fuel pump went. Check for power under the van at the gas tank for the fuel pump. You need 2 people to do this,the pump will only power up for 5 secs/key cycle unless the engine is running.

2002 chevy express fuel pump/crank sensor?? not starting


i had a similar problem and called the dealer during lunch hour. i talked to a mechanic, the distributor in these vehicles is plastic, and is prone to cracking.not just the cap but the body also, I have been taking the cap off and wiping the moisture out of the cap. or replacing the cap but the problem is I need a new distributor. just a cheep way to get rolling is cleaning the inside of the cap, especially when it is very damp or the outside temp changes alot during the day. good luck.
