99 GMC Jimmy
I am told my jimmy needs a new fuel pump
.Now while.idling I get a smell of carbon buildup coming up till I rev it up and it smooths out for a little.Once I start it up espexially on a hill and gas it it doesn't wanna go.I have the pedal to the floor.Then it takes off.I also have two codd read outs for heater sensor or o2 senaora bad.Would the fuel pump cause alot of there issues along with the sensors??
