    So i should change the fuel filter and not the pump, or both just in case? I live in the Chicago area so its pterry cold here. Actually, the last time I filled my tank (yesterday) i put in a bottle of heet.

Try changing fuel filter first, if not replaced recently. What's the weather like in your area? Cold, maybe try some gasline antifreeze or "heet" in case of bad tank of gas?

    I'd go fuel filter first, it's much, much cheaper, and if it turns out to be pump, you already have the new filter which they would normally change if pump done anyway. If you can, get fuel pressure tested before anything, and that will help determine if that is your problem area. Shouldn't take any more than 10-15 minutes to have it checked. when vehicle is acting up is the best time to have it checked if at all possible, and if fuel pressure is normal, they can concentrate on other areas that may be suspect.

2004 nissan turn over but wont start. replace fuel pump and still got the same result


could be a problem with engine electrical or still with fuel delivery. unhook a fuel injector line while it cranks and see if it shoots out spurts gas, just as the fuel pump line is supposed to shoot out a stream of gas while cranking. if you replaced the fuel pump, and no gas shoots out the disconnected fuel pump line, there is an electrical problem, (fuse, relay or wiring issue) to your new fuel pump. if the gas spurts out the loose injector line, then move on to electrical:

first ensure your ignition coil has spark by disconnecting the coil ouput lead and shorting it out to the chassis of the car. you should see a spark, when you short that circuit while cranking. if you have spark, you will have to move on to the spark plugs/ cables, then the distributor cap/coil packs.

if its part of the electrical system, it will be sensitive to temperature/humidity, and that may be why it only fails to start early in the morning. if it were the fuel injector, it would be more likely to start cold, and NOT re-start after it had already been warmed up and cut off recently.

wont crank as in turn over or wont start? if it wont start it could be a fuel pump. if plugs have spark its fuel related . when you turn on the key most pumps make an audible hum for a few seconds to pressure up the lines for starting

My mercedes 1999 cuts out and wont start 30mins later it will


this happens on my partners a class but only when the fuel gauge drops to 1/4 full.Now we keep it filled up with no problems.We had the fuel filters replaced without success.I think maybe there are fuel sensors which are telling the car it is out of fuel.Like yourself we would wait for a while then the car would start.

05 ford five hundred wont turn over thinking its the fuel pump or maybe the relay


try banging on the fuel tank sometimes that could make the fuel pump work for a bit, you cant 100 percent rule out a bad fuel pump;you may have a better idea if it starts. good luck

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.
