Why is my truck flooding itself out with gas

8 Answers

I'm not sure why


What engine does it have in it?



That has the fuel pressure regulator instead of a return line to the fuel tank. Have you checked your fuel pressure? You should check it to rule out the fuel pump. It should read 49lbs. You might have 1 or 2 stuck open fuel injectors. Another thing you can check is see if your O2 sensor fuse is good. Fuel control comes from your first O2 sensor.


If you pump turns on and the fuel pressure gauge shows 49lbs then your problem lies somewhere eles besides regulator, pump, and injectors. Gotta check your fuel pressure.

Ok I'll check that I don't no what sensor is next to the throttle body in left side but if I unplug that it runs ok for awhile but then it'll shut off


That's the TPS (Throttle Position Semsor) that could cause your flooding. A malfunction in the throttle position sensor can give the PCM (Computer) the wrong information about the amount of air entering the engine. The can cause the PCM to deliver the wrong amount of fuel, and either flood or starve the engine, causing a stall.

Ok that wat I think it is cuz wen I unplug it the truck reves and then it'll try n shut off I plug it back in then it flooding from to much gas.
