Hello.

Can be alot of causes. Most common:

Egr clap closed - doesn t allow air intake - car also blows black smoke while cranking.

Fuel intake
- low pressure fuel pump - located inside the fuel tank - may be burnt
- high pressure fuel pump - engine bay - also may be burnt
- not enough fuel inside the tank
- fuel leaks before reaching injectors

etc

Hope it helps

So my fuel pump has been making a high pitched noise for a while. Then one day, without warning, I tried to start the car but it wouldn't. It cranked but would not start. I turned the car on (not start)...


I looked at info for 3.1L vinM Buick regal. fuel pressure key on engine off, 40.5--47 psi. Can you check the vin? The fuel pressure specs I have for 3.8L engine are even higher than the 3.1L.
You will get a fuel pump prime, key on engine off. You need to make sure fuel pump runs with engine cranking.
My hearing is no good, I can't hear fuel pump with engine cranking.
Sometimes If fuel pump brushes are bad, the fuel pump may run intermittently. Sometimes you can bang on bottom of gas tank when trying to start and the fuel pump will take off running.

2000 Dodge neon starts and runs fine. But sometimes does want to start Engine cranks, but won't start


How many miles on the car? Have you checked the fuel pressure when it doesn't want to start? Do that first and then move on from there. To quickly test fuel pressure with no special equip get a can of starting fluid from the auto parts store, when it fails to start spray the fluid into the air intake of the engine well it is cranking, if it fires up then the fuel pump is likely not running on for some reason. This can be electrical in nature or just a failed electric fuel pump

2009 chevy aveo ran out of gas now it wont crank


No crank to a mechanic means the starter motor doesn't spin the engine over, is this what you mean? Or do you mean the engine cranks over but will not fire up and run? If it is the latter have you added at least 3 gallons of gas to the tank to make sure the electric fuel pump inside the tank can properly prime? If not do that, also you can spray starting fluid into the engine engine air intake pipe after adding the 3 gallons and see if that gets it going. If it still will not start you have burned up the fuel pump and you will need to drop the fuel tank and replace the pump, remember the pump is cooled and lubricated by the gasoline it runs in, so when you run low on fuel or out you can very quickly severely damage the small electric fuel pump. Never let the gas gauge level go below 1/8 tank to prevent premature fuel pump failure.

The engine turns over but the motor will not start. The van was running fine when it was cut off. It doesn't seem to be getting gas.


It's very likely your fuel pump has failed. Have somebody thump on the fuel tank while you're cranking the engine and see if it starts. If it does, replace the fuel pump. Otherwise get your fuel pressure checked, and check for spark. If no spark, check to make sure the distributor is turning(if applicable) If a 3.3 motor with no spark, suspect the crank sensor or cam sensor. Crank sensor is much easier to replace if experimenting.

98 chevorlet lumina runs good for about 15 to 20 minutes a shuts off


If the fuel pump is still making a noise and the engine doesn't start when hot. Possibe Crank Shaft Position Sensor. (not real nice to do) Can also be the ignition module but more often its the Crank Sensor. There are some simple tests if you are handy with cars?

I have a 2003 Kia sedona ran out of igas now wont start the code I get say crank posistioning sensor will that cut or cause the fuel pump not to work cause I get no humming from it the code is p0335


No this does not affect the fuel pump. It will affect the spark though. Hit the gas tank in the center a few times. If it starts then replace the fuel pump. Unfortunetly pumps with a few yaers on them will die when ran out of gas. If it doesn't start pull one of the spark plug wires, insert a screwdriver and put it close to the engine. crank the engine and watch for a spark. if there is no spark then replace the crank shaft sensor. before you replace the fuel pump.

2001 BMW 530, car turns over fine but sometimes just cranks and cranks without the engine starting. Battery turns engine over great but wont start. Next day starts great all day, then acts up again and...


sounds like a fuel pump or filter problem. replace filter first its cheaper than a fuel pump.my fuel filter on my 01 530 was under the driver side half way back along the bottom rail of the car.i had to remove the aero plastic with a plug puller that gave me acess to it.try and replace that first. if it doesn work its prob.fuel pump.

Want start or turnover


First ck for fuel pressure.Turn key on and listen for buzz sound near rear in gas tank. This is your fuel pump and when you cycle key off then on it should make noise for 2-3 seconds. If not have someone bang on fuel tank with the palm of their hand while you crank engine if it starts replace fuel pump. If no noise remove black cap on fuel rail on top of fuel injectors and push shrater valve with small screw driver and fuel should squert out. (this valve is the same as a tire shrater valve that you put air into) If not or very little fuel comes out then your fuel pump is bad or fuel pump wiring.Before replacing fuel pump take a test light and check the power wire and ground wire at fuel pump while cranking engine.If fuel system ok reply back for next step.
