I had that problem before and it ended up being the fuel pump, the easiest way to check its disconnect the fuel filter line and let the pressure release till nothing comes out and then have someone else crank the car point the hose away from you, if it shoots out then the pump is good, if it does nothing, its not pumping fuel

How do i fix the leaking fuel injector?

A leaking fuel injector is a dirty fuel injector. Remove it and clean it by either spraying or soaking the injector in carb and choke cleaner. After cleaner runs clear dry completely with compressed air. Always replace the o-rings, soak them in clean engine oil for easy install and a tight seal. If you should need further assistance, drop me a line.

Why won't it start after running out of gas?

Hi Joe:
Don't know what "it" is, but the fuel pump needs to cycle enough to prime, the carb or injectors need to be filled with fuel.
If it is a carb, remove the air filter and look into the carb...... pump the throttle linkage...... the accelerator pump should squirt gas into the throat of the venturi. If there is no gas, a squirt of gas to prime won't hurt.

2001 Hyundai accent wouldn't start this morning after sitting two days prime and no codes kept screwing with it I primed and runs then only primes sometimes but still runs great miss chug

Hi Miss Chug:
I'd start by using some carb/injector cleaner and make sure that the fuel delivery system is working properly.
If this is a carb type engine, make sure the automatic choke is not sticking.

Cleaning injectors on 4.9 ford inline six

You can have them professionally cleaned, but I have made a wiring harness with an injector plug from old harness, sealed pushbutton switch, and battery clips. Remove injectors, one at a time hook up and breifly energise injector and use carb cleaner to back flush injector. This will clean the screen filter and usually restore normal operation. CAUTION carb cleaner spray is flammable so all wiring and switch must be no sparks.

Is there something that could cause a Coil to keep going out on a 2002 Toyota Echo?

The compression is not the problem, it's possible that you just got a defective coil or there may be an intermittent problem with the #4 fuel injector, the P0171 will come back when there is a misfire once the misfire is fixed the P0171 will stay gone, a fuel injector seems logical since if it's sticking it will drive the system lean which is what the 171 code is for.

Have a 90 f-250 5.8 gas burner. sat in a warehouse for 2 years. new battery and gas. starts and idles great. run up rpms for 2 minutes and it starts choking out. let off fuel and goes back to idling...

Carburetta is fouled. Run fine on choke - rich mixture. As it warms up and choke pulls off, its starving for gas.
First try adding fuel system cleaner to the gas tank. Do NOT go overboard. No more than double the recommended mix ratio.
The alternative is to remove the carb, open the bowl and spray out the jets and venturi with carb cleaner.

Its possible you may help it by removing the air filter and spraying every orifice you find on top of the carb. With carb cleaner. Be very carefull not to flood, pool carb cleaner in intake as this is not healthy for engine either. You can do this with engine running, so as not to pool, but slowly is best, both in engine speed and volume of carb cleaner.

Engine Shaking or studdering at 73km/h

first try a gas system/fuel injector cleaner or carb cleaner .if its a carbarreted system its in your four barrel side, fuel/air mixture. if it fuel injection your fuel injectors maybe dirty, and possible the fuel filter. if not motor, then you may need a front end alignment.

Once car warms up it dies when you press on gas. Then it will not start at all.It turns over but will not start. I am getting fuel and spark.........?

On cars with a carb, you could point to lean fuel mixture. Runs rich enough when it's cold, because the choke makes the fuel mix richer. When it's warm. you no longer have that"rich" mix from the choke and then it's too lean to keep running. Could be a dirty jet, dirt in the carb, Dirt in the fuel. the list goes on. Needs rebuilt or blown out with carb cleaner spray works sometimes. Dissasemble and clean out with compressed air.
With fuel injection, Throttle bodies, it could be a dirty throttle body, injector,etc, Port injection, could be a sensor or some thing controling fuel, a bad couple of injectors, really not sure. Or a sensor of some sort. If you could get it to Auto zone they will scan it for free and tell you what it needs. Hard to put a finger on it with out seeing it. Have you tryed a good fuel cleaner like lucas? Do you run the tank below a quater tank? This will cause troubles. Best of luck, Those Quad four's are a great motor. lbreen

Cannot get 1987 chevy van 20 to keep running... stalls out

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.
