Like the title says i am blowing the 10 amp ecm/sol fuse. As soon as i key the ignition it popped,so its a dead shrt im sure. But know where is it,and what is all part of this circuit. Is there some coming wiring issues or places i could start.the car will start and rum,but i noticed it is not charging also. I pulled the alt had it checked,pulled battery had check both are good.So know where to start. is it a relay or something? any helped would be appreciated guys thanks in advance.
 
I had a bad ignition module on the T-type that caused the ECM fuse to blow. I am 90% certain it was the same fuse. If I remember correctly, there was a test procedure in the factory service manual.
 
That fuse runs the brake switch, wastegate solenoid, canister purge solenoid, coolant fan delay relay, Electronic vacuum regulator valve, A/C cutout relay. Powered by pink/black wires.
 
well dont have,waste gate soenoid,canister purge.or electronic vac, hooked up. So down to coolant fan relay and a/c cut out relay. Which relay is the ac cut out?
 
I will look and see when home, the relay pink and black I know had no power from it on pink and black . But it popped fuse as soon as keyed so, I'm sure tht don't help...lol quick looks at plugs didn't ee any melted endd but I look real good after work.
 
It also runs the Torque Converter lockup solenoid which is the one that usually shorts inside the tranny pan and instantly blows the fuse.

Try unplugging the 4 wire connector on the side of the tranny and see if the fuse holds, if it does you have found it.

It can be the solenoid itself but usually the wire +12 wire gets pinched or pulled and shorts to the metal grounded parts down there.
 
Well after reveiwing some of the places to check, i found the problem.It was the plug on the torque convertor lock up, I recently had trans out. And had my brother helping to install trans and some how the plug got plugged in wrong,causing a direct short. Unplugged it. plugged fuse ,key up no short. So plug sensor back in all is good. Thanks guys for the help was just a simple mistake,and my brother feels like a dumass for plugging in wrong...lol.

but again thanks for the point in a direction.
