Possible Throttle pedal issues - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I was driving my LFX powered Chevelle up an on-ramp today and the throttle pedal seems to have quit or failed. The car lost power so I pulled off but it never died, just went to an idle.
When I push on the throttle pedal, nothing happens.
I don’t have my code reader with me (I’m still on the side of the road waiting for a tow truck) so I can’t check anything from here,
Any preliminary thoughts???

Connector come undone?

Update: I just realized my Scan Gauge II can read codes so I ran it. I’m getting a P228C code. Fuel pressure regulator sensing low pressure. I’m guessing my fuel pump just too a dump.

I’m betting it’s not the fuel pump

What’s your guess?

A sensor….either at the accelerator pedal or throttle body….that’s my Guess…if it was the fuel pump the engine would starve for fuel and die
