Truck wont start after running out of gas put gas in 3 different times from gas can wont statt


Have you tried listening to see if you can hear the fuel pump run?

Try pounding on the bottom of the gas tank with the palm of your hand. Sometimes that can jar the fuel pump enough to get it to run.

You can also try putting a small amount of fuel in the throttle body and see if it starts. It won't run long but, if it starts, you know you have a fuel delivery problem.

You need to have the fuel pump pressure checked. Many times a fuel pump will run but won't have enough pressure to feed the injectors. Each vehicle has different pressure requirements find out what yours is, then rent a fuel pressure gauge from your local parts store before doing or replacing anything. Good luck

I HAVE A SLIGHT PROBLEM, 2 LITTLE THINGS WITH MY 1990 FORD BRONCO. THE ONLY WAY IT STARTS IS IF I POUR GAS IN THE THROTTLE BODY, IT RUNS FOR A FEW MINUTES AND THEN IT SHUTS OFF. I CAN HEAR THE FUEL PUMP...


It sounds like the problem is not fuel pressure (check it at the schrader valve on top of engine) but that the fuel injectors are not delivering fuel to the engine, this can be no power to the injectors (red wire should be hot with key on) or a burnt out ECM.

Where is the carburetor on my 93 mercury topaz?


There isn't a carberator on your 93 mercury topaz. It is new enough to have electronic fuel injection (EFI).
When you say it wont crank, does that mean the starter wont turn the engined over? Or do you mean it wont start?
If the starter turns the engine and it wont start here's a trick that might work. Turn the ignition key to on but don't engage starter. Listen for a buzzing sound coming from underneath the vehicle near gas trank. The buzzing sound is the fuel pump pumping up pressure. The buzzing sound might last only one to two seconds. Then turn ignition key off and turn it on again NOT engaging the starter several more times. This will help prime the fuel up to the engine. After you've done this several times, the engine should start. Lt me know if I was any help.

Have changed fuel pump in 2002 jeep liberty and it wont start,yet when u spray gas into throttle body it will run


Obviously the new fuel pump isn't running

Get a wiring diagram of that circuit and find
out why

Do you hear the pump when you cycle the key?

Did you check fuel pressure before & after the
pump change?

Fuse good,grounds & pump harness connector?

Correct pump?

I think you should probably rebuild the throttle body if you have not. Over time, some serious **** can build up in the body and also, the gaskets can shrink due to age which can cause fuel blockages in the body its self.

Wont start , no fuel getting to fuel pump


Are you sure there is gas in the tank? I "fixed" more than one car that came in for a fuel pump replacement that ran out of gas. If you have gas, check the fuel pump fuse, fuel pump relay, check for power to the fuel pump. check wiring, kinked lines, clogged fuel filter. Sometimes new FI cars are hard to prime if there is air in the system. Take off the air filter and have someone squirt fuel down the throttle body while you crank the engine. If it fires, you know it's not getting fuel, but when it does fire , it may prime the pump enough to run.
