Question about 1989 Ford F 350

Open Question

I have a 1989 Jamboree RV. It has a 426 ford

I have a 1989 Jamboree RV. It has a 426 ford engine. And I think it is throttle body fuel injection. I pulled in to a gas station to get gas and it would not take gas, it fed back. I tried to start it and it would not start. It has a vacuum pump, a filter and a fuel pump in that order on the lines. I pulled the fuel line and it has gas flowing.

I have a 1990 for jamboree rv and it idles fine. But when give it gas it dies. I have replaced the fuel filter. What could it be?

Probably the throttle sensor, has the car ever overheated? if yes then replace the sensor and the throttle body.

Do my 1996 gmc box van engine fuel injection or carburetor

If you see a fuel rail or a short-throat throttle body, it is fuel injected.
If you see a carburetor... well, I think you get the point :)
From the year (unless it is a non-U.S. model), it is most likely FUEL INJECTED.

1989 ford stalls when idling ,runs rough at idle

Check for any trouble codes in the engine computer, and have the fuel pressure tested. If it is throttle body injection. observe the spray pattern of the injector when it pulses. You should see a cone pattern of the fuel spraying down into the intake. If it drips, or appears anemic, the injector might be partially clogged. Try some injector cleaner in the gas tank.

1989 Ford f150 4x4 6cl When I go to start the truck it will start then I must keep pumping the gas peddle to keep it running if I let off it will die. Even when it is running it runs very rough

Check your fuel pressure to seeif it is high enough. Possible fuel pump or filter which some of those trucks could have up to three fuel pumps, one in each gas tank and a pump along the frame also. Could also be a vacuum leak or a suction leak at the intake or throttle body. Another possibility could be throttle positioning sensor. An easy way to check for a fuel related problem is to lightly spray carb cleaner onto throttle body while trying to start and see if it will continue running on that. If it does then you have a fuel problem. Use carb cleaner safe for fuel injection systems.

Were is the fuel pump on a 88' oldsmobile cutlass ciera

If its a throttle body injection or multiport fuel injection the fuel pump is in the gastank, If it has the optional carburator for that year then it is on the engine block.

Car won't stay running its like its not getting gas (and yes tank is 3/4 full) shop is telling us its a computer problem.. i didn't think 1989's had a computer. car is a 4cyl automatic

Your 1989 cavalier is a 2 liter fuel injected engine so yes you do have a computer to run the engine so check your fuses and start with the simple and replace the fuel filter, air filter and clean the throttle body with throttle body cleaner. Don't use carburetor cleaner, the carburetor cleaner is to corrosive for the gaskets used in the throttle body. Also make sure all the vacuum lines are connected and not damaged, a bad vacuum line to the MAP sensor will cause what your having.
Good luck and keep us posted. Be glad to help you get your car running 100% again without the cost of a garage trying to be like the tax man.

Where is the fuel injector located on a 4cycle ford ranger 4x4

I'd guess with a 1989 you have throttle body fuel injection, which means that the "injector" is in the metal part that would be where the carburator used to be. Old cars had the air filter on top of the carburator.
you really can't see much of it.

Where is the fuel pump regulator located, the truck starts but wont stay running

If you have a throttle body injection it's on the throttle body. If you have port injection, it's on the end of the fuel rail.

Fuel pump

With a vehicle that old I think you should retrofit any pump that matches within reason the original specs as with throttle body injection fuel pressure is critical. If it is the same as South Africa the agent will sell you any **** to get rid of you. Try fitting a Bosch pump with a pressure regulator (set it to spec ). Please change the filter.
