It could be the fuel pump or a clogged fuel filter or another part.
Could be weak fuel pressure from a bad pump or clogged filter but it could also be other issues like a dirty/faulty IACV or vacuum leaks, etc. Given the age of the truck, you might try changing the fuel filter if not done already or due and clean/test the IACV which is used by the PCM to controls idle speeds. Over time, the IACV… Idle Air Control Valve… Can get sooted up with carbon and not operate properly which can cause stalling, low rpm's or hard starts, etc. Check for any vacuum leaks and test fuel pressure if needed.
No. It can be a lot of different things. I'd start by cleaning the throttle body. Then have the idle air control motor inspected to see if it's working.
- Location of 1998 Ford Taurus fuel pump. Does it have a fuel cut-off switch? Car shut down suddenyl without warning. New battery and cranks but will not start. Suspect bad fuel filter, 130K miles and fuel filter has never been replaced.
- Rpm gauge not working normally? I have a 2004 Ford Freestyle and I noticed today my RPM gauge has been acting funny. When I turn the car on, rather sitting just above 0 it is sitting at one. When I start to accelerate it would normally go up to a 2 but instead it is going to almost 3. It is an older car with 150k miles on it. I'm not car savy in any way but I want to know what could possibly cause this and if it will be an expensive fix or not.
- My 1999 ford ranger has 20 lbs of pressure on the fuel line. Do i need a fuel pump? After I tested the pressure and shut the motor off the pressure went down to 0 quick. When I just turn the key I don't get any pressure
- I have a 1994 ford ranger and my tempature gauge is constintly going up and down? When I drive the temperature gauge will rise up above the half way point and then it will go down Almost all the way and will just keep doing that until I turn off the truck. Anyone know what could be the cause of this?
