If your Mitsubishi 2800 Colt TDI is stalling or stopping when you accelerate, it could be due to a number of issues. Here are some possible causes:
Clogged fuel filter: A clogged fuel filter can restrict fuel flow to the engine, causing it to stall when you accelerate. A mechanic can replace the fuel filter to resolve this issue.
Faulty fuel pump: If the fuel pump is not working properly, it can also cause a lack of fuel flow to the engine and result in stalling. A mechanic can test the fuel pump to see if it is working properly and replace it if necessary.
Airflow sensor malfunction: The airflow sensor measures the amount of air entering the engine and sends this information to the engine control module. If the sensor is malfunctioning, it can cause the engine to stall when accelerating. A mechanic can diagnose and replace the airflow sensor if necessary.
Clogged or malfunctioning EGR valve: The EGR (exhaust gas recirculation) valve recirculates exhaust gas back into the engine to reduce emissions. If it becomes clogged or stops working, it can cause the engine to stall. A mechanic can clean or replace the EGR valve to resolve this issue.
I would recommend taking your vehicle to a qualified mechanic to have it diagnosed and repaired as soon as possible to prevent further damage or safety issues.
TRY THE FUEL FILTER FIRST IF THE FUEL PUMP WAS GOING BAD IT WOULD STALL AS YOU PUSH ON THE GAS PEDDLE AND PUMPING THE PEDDLE WOULD NOT HELP FUEL INJECTION AND PUMPING THE GAS WILL HAVE NO EFFECT ON THE RUNNING OF THE VEHICAL
Sounds as if your fuel pump is not operating correctly are has gone on the fritz. Of course it also could be your fuel line filter has been clogged up to the point of not letting the fuel flow. I changed two fuel pumps in a ford until I checked the fuel line filter and found it clogged. What it would do was to start and run at low speeds for a few miles, but when I accelerated it would force the gunk in the fuel line filter up to the end and block the gas flow. When I would let it sit for about ten minutes, gravity took over and settled the gunk in the lower part of the filter and fuel would flow as long as the fuel pressure was low.
Check the fuel filter first, then the fuel pump. I think that all of the fuel pumps are now in the gas tank and is a dickens to replace.
sounds like you got somethin in your tank or lines. Do you only have one fuel filter? Did you change your air filter by a chance? Start ther then let us know
Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
the problem sounds like it is not getting enough of fuel. check or replace fuel filter to see if this helps, also make sure fuel pump is pumping the fuel at the right pressure. have pressure checked if need be. if not enough fuel a vehicle will run at idle, but stall under pressure.
