Fuel Pump Control Module Checks

This video is an extract from the AutoMate Fuel Pump Control Module Checks Diagnostic Training video.

Electronic module control has revolutionised the modern engine fuel delivery system by enabling more precise fuel control, better reliability and lower NVH levels.

This additional electronic control means diagnosing fuel delivery system faults require a blended approach of both mechanical and electrical checks to ensure accurate diagnosis.

Would this fix P129D code my Cadillac srx? The fuel seems often acts erratic as if I'm losing a lot of gas even driving short distances and it doesn't fill up completely. There are no oil leaks either.

Your videos said that the module is inside the pump that is inside the fuel tank. Is that correct on a 2014 F250 super duty King Ranch 4 x 4 with a 6.7 diesel ? I have a P0627 code, with a crank no start situation, and getting lots of different diagnosis from different people on this one . Need help please. I am broke and have been broke down for 3 months now, as I had 13 codes to begin with and I'm down to one.

Many of you missed the point. Instead of just running a pump full blast all the time and mechanically regulating to a desired output pressure (even though volume varies a lot with load), a PWM system uses a pulsed consistent voltage with a feedback loop from a pressure sensor to maintain the target pressure regardless of volume or flow, and to not over run the pump too much.

Are all car mount with this kind of device?

so basicly you cant run the vehicle without the fuel control module?

[yipekiyay]

from what I understand that if my module is damaged could be the reason 4 burning too much fuel?
