Engine help

[ShreveSteven]

2013 Q5i owner here. 4.3L fuel injected engine. My baby seems to be starving for fuel as soon as I put her in gear. Forward or reverse. Zero power. Cranks and idles perfect. I've verified the tank is clean, changed the fuel water separator, removed the anit-siphon valve, replaced the injectors and the fuel pump. All fuel lines are tight at connections. I'm lost as to what the problem could be. Any help and I mean ANY will be gladly appreciated.

Welcome
Have a serial number of the motor?

What is the fuel pressure?

Does it use digital throttle system (DTS) or have a cable?

Not sure of the engine SN. But it's constant at 42 psi and it's cable

Even when in gear?

You said

Zero power.

What odes this mean?
It's in gear and will idle but not increase when throttle is moved, or something else?

Most likely your going to need to get the motor scanned but we can run through a few checks prior

Measure the voltage at the TPS, will have exactly 5V on one wire, a Ground, and a variable voltage on the other. With the motor off and key ON, measure voltage to see what it is at idle and how it changes as the throttle increases

We do need the serial number. Will find it on top the motor or on a plate above the starter riveted on the block
