Sorry if I'm posting this on the wrong section.
Last night, I wanted to make sure my aux fan is working, so I unplugged the connector between the battery and radiator and jumped it to the battery.... Didn't hear anything and the fan didn't turn on. Gave up, went to go fire up the truck to head out to the gym and it wouldn't start.
It cranks and cranks but won't start. The security light stays lit in the cluster. I tried the unlocking of the door with the key and cycling it three times but still no luck. Read the manual and it said to take it to a dealer if the light wouldn't turn off and the vehicle would fire.
I did just that today. Dealer calls me back and tells me that they're not sure what's causing the issue but that I need to replace my ECM/PCM...they want $1,100 for just the part!!!!!
Checked fuses and they're all ok.
Any advice gentleman/gentleladies?
