Asked by Eddieblanco1986 Nov 04, 2017 at 03:04 AM about the 2003 GMC Envoy XL SLE 4WD

Question type: General

So i have 2003 gmc envoy xl sle and yesterday leaving work
i turned it on while i smoked my cigarette then when i put it
in drive and started moving it shut off. I waited a few
minutes & tried again. Same thing happened and them just
didnt wanna start, it sounded like a fuel to air ratio problem
because it made like a clogging sound when i turned off. I
used my OB2 scanner and it read 4 codes all for the throttle
body sensor. I changed the throttle body and cleared the
codes. Then i tried turning it on it didnt want to and drained
the battery quick and the check engine light was on but no
codes.

I had the same problem with my 05 envoy, it's the foot pedal sensor

I checked the green cap and had no pressure from the fuel line so idk if i should change the fuel pump or maybe its the pedal. Does a. 03 have a pedal sensor. ?
