THROTTLE POSITION SENSOR

GMC Jimmy

We have been experiencing some trouble with our 1998 GMC Jimmy, 4.3L, 140000km - it won't start! We replaced the fuel pump, fuel filter and the regulator, and it still won't start. We scanned it and it says that there is low voltage to the Throttle Position Sensor. What should we do next? We really need to get this vehicle running asap!

I would have probably gone to a salvage yard and replaced the whole corner (lower arm, strut, spindle, caliper, new axle. Has the unibody been checked to see if it is ok?
