There can be several causes for this problem. The first thing to check is the fuel pressure. You can borrow tools for this at most big chain autoparts stores like Autozone. If you find that the pressure is Okay, then there is a different reason for your problem.

If you need additional help, please include the Brand of vehicle and Year and Model. Sometimes a common problem for 1 car is on record and it will be helpful in problem solving.

Often things like an EGR or TPS can be part of the problem. Another condition called "Limp Home" mode can be falsely activated and produce your results. You can sort through some problems by whether they activate the "check engine" light or not as grouping things to look for.

Please rate my info.

1995 dodge Dakota, fuel pump stop working after the truck it warms up. checked relay what else could it be?

It sound like a long shot but check your oil pressure sensor. It acts as a safety to prevent the engine running without proper oil pressure. When you first start the car, the fuel pump relay is controlled by the computer. After a few seconds, the computer cuts power to the relay which, by then, should be getting power from the oil pressure sensor circuit. If the circuit doesn't report enough pressure, the fuel pump relay will have no power to keep the pump running. It's just one of those off-the-wall parts that you'd think has nothing to do with the fuel pump.

I have a 2008 Cadillac DTS and its not getting enough fuel to keep it running what would cause this

A bad fuel pump, poor power or ground to the fuel pump, a bad MAF sensor, A bad coolant temp sensor, a large vacuum leak, an upstream O2 stuck rich, A plugged fuel filter, or dirty injectors to name a few.

Is there a check engine light on? How do you know it is not getting enough fuel?

Why is the petrol pump lose power when u drive 318i e46 facelift 2002

run fault codes and look for a tank venting problem Evaporator sensor /blockage and or blocked fuel filter not allowing enough fuel through to keep pace with the engine requirement. have a pressure test done on the fuel system to check that the fuel regulator is working as required.

Could it be fuel pump does not have enough power

if the car was running just not enough power why would you change the fuel relay as the pump is running unless you mean fuel you could have a fuel pump problem if its not able to run at the pressure it was designed to run.check the fuel volume as well.if the pump is running at the proper pressure the volume can be low and not supply enough fuel volume for the car to run at an and all thottle demands.another thing to check is the exhaust sytem being plugged up.just some things to check

1999 dodge caravan runs okay until you try to quickly accellerate or when attempting to go up a steeper grade. At these times it pops back through the intake and you lose power The power loss is worse...

have a fuel pressure check ran on the vehicle to make sure it is mantaining the proper fuel pressure at all may be holding enough to keep it running at low acceleration.i hope this helps

My car starts but no power to the engine as if not getting enough fuel to keep it running.

Check for a stopped up fuel filter or clogged catalytic converter. Either one can cause the car to run this way.

Car stalls, won't keep running after start. New battery, new alternator. Any ideas? I'd like to fix it myself.

Ya sounds like fuel filter is clogged.Id start there.If not then fuel pump is going out.Has weak pressure and has enough to start it after turn key on but not enough to keep it running.Id start at the filter first since its a easy and inexpensive fix.

Van turns over, but its not getting enough fuel to keep it running. Could it be the fuel filter? I have already replaced the battery. It has enough juice to run the radio and the door bell, but won't turn...

Most likely the fuel filter. But it could be the fuel pump if it is on its way out it may not be delivering enough fuel. Also could be clogged fuel injectors or bad idle air controller (IAC). Start with the fuel filter. If it gets better but still not quite rite then try running some fuel system cleaner through it. If the filter got clogged then some of the grit probably got through and in to the injectors.

Engine stalls right after start up has fuel press.

Fuel pump. It may have some pressure but not enough pressure to run the car properly. We just had to replace the pump on my son's 97 s10. It had a little pressure but not enough to run. Would start up and die as soon as you started into the throttle. They can check the pressure at a repair shop - you need a special guage.

No start/no power to fuel pump/ power at one small wire/relay fuses ok/

most newer cars have a relay in the fuel system to shut it off when fuel pressure drops below the norm. this keeps your car from running lean and burning a piston. i whould replace the fuel pump. the fuel pump may work when you take it out but that dont mean it has enough pressure to opperate your car.

hope this helps . good luck
