Question about 2002 GMC Envoy
Had stater relay checked when it wouldn't start and found 40 AMP fuse blown.Repplaced it and truck ran approx 2 weeks. Now it wont start and when I turn the key- no cranking, fuel pump pumps up, radio , windows, etc work.Locked in gear and wont come out.
Towed to garage (3rd time) and was told Fuse box/relay has a short in it.
Called dealer and they say they have never heard of that and they dont even stock a fuse box/ relay.
Could this be the problem? Mechanic hot wired starter relay in box and got her to run but it is jury rigged.
Any help greatly appreciated as these things cost over $475.00 Cdn. Thanks in advance.Mike
I read your problem.
Is there a few step to diagnostic or try to fix your car.
Follow this simple steps.
Inspect the RALAY " Starter relay # 47. or interchange with other one just for testing.
1- Check the Fuse " IGN E Fuse number 22 " 10amp. on under hood fuse BOX fron Neutro swicth
And power to the power to the Neutro safetly switch.
2-- Check the Fuse " CRANK fuse # 17 10amp. Under hood fuse box. 12v. from Ignition switch
3- check the fuse " IGN A fuse # 34 40 amp. under hodd fuse box. Constant 12v. to relay.
With ignition switch in ON position.
Crank Fuse only when you try to start. If no power 12v. come when trying to start.
REmove the steering column covers. to get axces to the IGNITION SWITCH.
Trying to start check if 12 v on the YELLOW wire exist. if not. Check if there a 12v on the RED wire
If not Inspect FUSE # 34.
But if there a power on the red wire But not ON yellow wire Trying to start.
Just REPLACE THE IGNITION SWITCH. Electrical part.
Check the NEUTRO SAFETLY SWITCH. connector under the car. Repair as need.
CHeck the BACK-UP lights, some times come damaged making a short on the Neutro safetly switch. ...
OK.. I hope this help on your problem.
