Hi everybody! I have enough gasoline, but the pumps doesn't runs properly. It seems that the low pressure pump doesn't feed the high pressure; it begins to whistle, more throttle I give. And the engine shut off. I replaces all the pump body - 2 pumps with the filter - but nothing changed. Can it be a problem of the ECU?

I removed the main gas line from the tank, and tested with a small tank directly in the filter. No way! It looks like the low pressure pump doesn't work ... but I tryed with a new one!

What is the full model number (the letters after the 5.0Gi), or the serial number of your engine.

5.0GIPEFS is the full model number for your engine.

Here are some test procedures for your fuel pump system.
