alot of info to go off of. It could be one of the following simple problems. Low coolant due to small leak on pump or hose. Busted water pump shaft so pump not working. Faulty thermostate. If all I've stated seems like a forgein laguange to you, take it to a shop.

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

SOURCE: 2001 GMC Jimmy break lights not working but all

Check the brake light switch should be a orange wire with 12v then a white wire with 12v when the pedal is pressed.If htat cks good then ck the hazard switch by moving it up and down and wiggeling the knob with the brake pedal pressed if they start working then your multifunction switch is bad and needs to be replaced.

Where is the fuse panel that controls cruise control on a 2001 jimmy gmc


It may be in the fuse panel under the hood. If it is ok, check the cruise control kick out switch operated by the brake pedal. If mis adjusted or knocked out of position cruise will not work.

2001 GMC Jimmy fuse problem INT BAT fuse?


This would be like looking for a needle in a hay stack, the right way would be to get a wiring diagram showing wiring from INT BAT and tracing the wires to make sure if its not short to ground.
And dont put fuse more then 50amp or else the wiring will melt and you may have fire.

2001 Jimmy shut down while driving. The ECM1 fuse blew. Replaced fuse and it blew. disconected circuits related to ECM1 fuse. reconected one circuit at a time. Fuse did not blow and Jimmy started. Why?


The first thing you should do is to locate the oil pressure switch/sending unit.

It's a single wire terminal with plastic connect sensor from the engine block.


This switch serves two functions.

1) provide oil pressure reading

2) disable the fuel pump relay in event of oil pressure loss.

===

When this switch is failing to provide the correct pressure to the ECU. The wiring harness can overheat and eventually create a short.

ECM1 fuse blow is because the harness is grounding/shorting.

===

DO NOT drive the truck until you change the oil pressure switch.

After you change the switch,you should spend sometime to inspect the wiring between the fuel pump relay,ECU and fuel pump.


Please post up day on the comment window/page.

I will follow up on it later.


Good luck.
