Question about 1987 Ford Ranger

1 Answer

Fuel pump will not shut off, no spark, cyldrs fill with gas

When I turn the key (Not to start) The fuel pump comes on and stays on. Gas fills the cylinders and comes out of the spark plug holes.(I have them removed) When I check the fuel pressure at the regulator the guage reads 42 psi. I also discovered I have no spark as well. Both electronic fuel pumps are new. I replaced the ECM relay and fuel pump relay. I checked the oil pressure switch (It's good) and I put in a new ignition switch. These problems happened all at the same time.

    Have you checked your fuel pressure regulator, to be sure vacuum line attached & in good shape, and connections all good?

Every time you try to pump gas, the gas pump shuts off every 5 seconds. Doesn't matter how slow or fast you allow gas to come out. Doesn't matter what gas station. You never know when it is filled. Gas...


try disconnecting the fuel line leading into the fuel pump, let out a little fuel, then reconnect it. then disconnect the fuel line leading out of the fuel pump, letting out a little fuel.
if that doesnt work, run the car completely out of gas once. turn the engine over a few times while empty.
have you tried pumping gas with the enigine running? see if that helps. if this does help, it is probably the vacuum someplace, near the fuel injectors?

Wont start unless i use starting fluid then wont stay running


with some one turning the key and some one at the fill tube where you put gas in. With your ear close to the fill tube the other person turn the key on you should hear a loud humm. If you dont hear the humm i would probally guess on it being the fuel pump in the tank. A another way to check to see is locate the fuel rail and on the fuel rail there is going to be a tire valve stem cap unscrew that turn the key on and see if there is pressure by pushing the center and see if there is pressure . Now there is gas in the line and if there is pressure it is going to come out pretty fast so be careful.So that is the two ways to check to see if you are getting fuel to the engine.

2002 alero turns over wont stay started sudden problem


It sounds like it may be the fuel pump. Have someone turn the ignition key to the 'On' position (don't start car) and listen to hear if you have a whining coming from your fuel tank. If not, your pump is bad. If that's not the culprit, then check your gas. You may have had a bad fill up. Try adding some octane boost to your gas and changing your fuel filter.

Car shuts off as if starved of fuel remove fuel line and prime car starts


There's a fuel pump relay that turns on the fuel pump, as you turn on the ignition before the engine starts, to prime and pressurize the injectors. I'd check the relay it may not be operating.

Ran out of gas, now wont start


if it was out of gas completely, after filling with at least 5 gal, turn key on, without starting. You will hear pump come on. After pump stops, turn key off. Repeat this procedure three times an the engine should start after the third time.

Let me know,

Car wont start


THere is no gas in the fuel rail at the time gas is running out. WHen you fill the tank, it needs to pump for a while so fuel can fill up the rail then the Fuel distributor so it can build up pressure for the injectors to work properly. It need to continue cranking at least 2 minutes. However you don't want to run out the battery, so can just turn on the key to hear the sound of the fuel pump stops, then turn key off turn key on again. Repeat this for 6 times then start the engine. The reason for it is that every time the key is on it turns on the fuel pump to prime the line then turns pump off after a specific time, then it turns on again only when key is at ignition position. By doing this you help to pump gas into the fuel rail instead of the starter continue cranking draining down battery fast. Cheers.

93 mercury villager ran out of gas. filled with gas will not star


When you ran it out of gas you may have ruined the fuel pump. They are very touchy. you can check it by having someone listen under the car by the fuel tank and you turn the key to the on position, be sure not to try and start it. When you turn the key to the on position you should hear the pump prime its self. If you dont the pump is bad if you do then you might look into the fuel filter it may have gotten clogged when it ran out of gas.
