Yeah i have a similar problem with my truck, and when we would go kick the gas tank for a bit, the fuel pump would start up again then we could drive it. so im actually going to install the new fuel pump today, and that is most likely your problem.

What may cause a difficult to start situation? It usually takes 3 attempts, cranking the engine (10-15 seconds), before it will start.


You would need to know if you are lacking fuel pressure or spark when the problem happens to know which system to test.
A relay or ignition component could be getting hot and not working, or the fuel pump could be loosing pressure.

My Honda accord 2003 has trouble starting first of the day. Starts fine for the rest of the day, what could this be?


One thing that happens on older Hondas is that the fuel pressure bleeds off when they sit overnight. The fuel pump puts out 40 psi, and the system is supposed hold that pressure when the car is off. The check valve is weak. Then you try to start it and with no fuel pressure it takes awhile to start, and may run rough for a few seconds. To see if this is the cause, on your first start of the day, turn the key on but don't try to start it. When all the warning lights are on. The fuel pump will run for 2 seconds, then turn off. If it is quiet enough, you might hear it, or the main relay clicking off after 2 seconds. Cycle the key on for 2 seconds and then off, do this 5-6 times. Then try to start it. If it starts right up, you know the problem. Most people just accept this, because the check valve is part of the fuel pump, and this isn't cheap.

1999 gmc sierra 2500 6 liter ran out of gas now won't start


If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!

I turned off the motor and five minutes later I wanted to start it up again. The engine turns but doesn't start. I noticed the fuel pump doesn't kick in before I tried to restart. What can the...


Bad relay. Bad fuel pump. You can go to the fuse/relay panel under the hood and swap relays with another one like the A/C relay and try it.
Then the pump may have gone. One common cause is driving with 1/4 or less tank of fuel. Fuel in the tank is very important now days as it keeps the pump thatis inside the tank cool.
Also if you turn the key and don't hear the pump, wait a few seconds before turning it again. If you turn the key off and on too fast the system does not respond that fast.

Never had a problem befoer. Was driving the car and lost all power. tried to restart it but it will only crank and not turn over. Had an oil change the day before and replaced the oil filter, maybe...


Lets try to see if it is a fuel pump. Get some carb cleaner and unscrew the intake hose ( air filter hose ). Be careful not to spray the mass air flow sensor and open the throttle body valve and spray in the intake while someone tries starting the car. If it starts then dies, it is your fuel pump. If it does not start check for spark by pulling a spark plug or using a timing gun. I hope this is helpful.

Takes multiple times to start


I think you have a faling fuel pump or a bad pressure regulator allowing fuel pressure to bleed down when the engine is off.
Try this test - When you start the car for the first time of the day, turn the key to "ON", wait a few seconds, turn the key off. Wait about 15 seconds, turn the key to "ON" again, wait a few seconds. Then wait one final time for 1 seconds and try starting the car. If it starts right away, that means fule pressure is bleeding of due to a bad check vavle int he fuel pump, a bad fuel pump or a bad pressure regulator.

The reason for the procedure is because when you turn the key to "ON", the fuel pump runs for 2 seconds and then shuts off if the engine is not running. The 15 seconds wait is for the power and fuel pump relay to cycle off before it will run the pump again.

Let us know how the test comes out. The fuel pump is in the fuel tank and hums when it is running.
