No...that keeps your vehicle from starting in gear. Is it automatic or standerd shift?

Have you had problems with the vehicle not starting at times as well?.......if so and it is a GMC product then from my experience it was the key-switch harness cable $50 will buy you on on ebay...or pay $200 at GM.....mine did the same thing and also would not change gears...started driving in 2nd or 3rd gear.....as this is the cause as well....good luck....everything was fixed with mine..1..gauges not working 2 pressing hard on the key switch to start and when it did could only drive in 2nd or 3rd gear......

That was common back then. You will need to get the diagram for both trucks and re-splice wire for wire. Also make sure the pink wire is powered up.

Does it seem like when the engine is cold it runs ok, then when it reaches operating temp. it starts acting up? (poor acceleration, stalling) When I had that problem w/ my 93 K1500, it ended up being my oxygen sensor. (causing too rich of a mixture in the throttle body) Hope this helps, Good luck

If your key unlocks the ignition lock cylinder but it wont turn far enough to get to the crank position, you may have a bad ignition switch. The switch is NOT the part near the steering wheel where you insert the key, there is a long linkage rod that runs down the column to the switch. The switch itself is located on top of the steering column up under the dash near the brake pedal. It is mounted with slotted holes for adjustment on a metal bracket with a plastic body (usually white plastic) I think it has two separate plugs with several wires in each one. It could also be the lock cylinder/rod mechanism in the upper part of the column is binding. you do not want to attempt to take that mechanism apart if you don't have the special tools to do it properly.

check that you didn't turn on the light by accident . its on the panel light dimmer switch

run fault codes and check for OD servo/ solenoid as this will over heat the oil

more than likely its the multi-function switch that is the problem...(on the steering colum)

Is the pump getting power from the pump relay ? Can you jumper the relay to make the fuel pump run ? And are the injectors opening ?

start at the bottom on the crankshaft then go to the left side of the fan(the belt will be on the smooth side)and then come around the bottom of power steering pump,over top of the alternator,then under the tensioner and over top of a/c

The reverse light is control via the linkage to neutral safety switch. Moisture can collect inside of the neutral safety switch.

Thermostat may be stuck open. If there is a lot of rust in the water the heater core can be plugged. Get a back flush kit and put it in a heater hose to push the mud out of the radiator and heater core.
