Mk111 turbo won't start

is the wire that goes from the harness between the head/intake hooked up? should be a black wire with a blue stripe, plugs into a hard to see spot on the starter, its the switch wire for the starter to engage, if it is just start working your way back, relay, clutch depression switch, ignition switch, checking all grounds along the way, had this same problem after i replaced a BHG and it was simply the wire

I will check in the morning. Thanks. I have been going through my tech manual to see if there is anything else. Been staring at all of the diagrams. Seeing that the fusible link is a cause of alot of the issues that are going on so will check all that in the morning too. Will let you know what I found in the morning.

Alright well checked the wiring from the starter and solenoid and I noticed a green plug above and right in front of the starter that is not plugged into anything and I can't find where it is supposed to plug into. Any ideas

Ok another question. We removed the spark plugs to lessen the compression and tried to pull it to see if the motor would turn. All we got was tires dragging. Tried in 5th to 1st gear. In a chevy or dodge the motor is seized. But I have heard different from others when it come to the supra. Is that correct that it is something else or is it seized?

i would say try a breaker bar to turn the motor over. if you did that and couldnt get it to turn over, prolly siezed :/

dragging with the car in gear doesnt always work.

you can always hotwire the starter to turn things over.

the green plug im trying to remember what it goes too. could you post a pic of it?

idk what the green plug could go to, i know thats not the one for the starter, the one for the starter will have a female end for a connector that goes into the side of the starter kinda on the back towards the passenger side IIRC, i spotted the connector with a mirror and had a hard time gettin the wire plugged into it

Well tried the breaker bar and nothing. Gonna try to use some diesel to soak through to see if can break it loose. Yeah the plug I guess from what a friend told me earlier is that it goes from behind the starter to the transmission. He said it really doesn't need to be plugged in but in my opinion it is there for a reason. What that is I have yet to find out. Any good advise to try to breaking the motor loose?

If its a non turbo, you could try taking out the distributor and turning it. I actually had this happen to me, the distributor seized in an 86.5 n/a and the engine would not crank.
If you cant turn the engine with a breaker bar, I'd bet that it is seized. You can try diesel but chances are it's gonna be hurt even if it frees up. It aint no Chevy! If you were planning an engine build, now would be a great time.
EDIT- Also had this happen (on a camaro). It turned out that a couple mice had chewed through my air filter, crawled in through the intake all the way into the cylinders and completely filled a couple cylinders with corn kernels. Where the hell they got all that corn, I still dont know (I live in Chicago!). They had quite a stash in there, enough to prevent the engine from turning. When I started pulling the spark plugs, corn was pouring out of the holes. They had also chewed through a bunch of wiring under the hood. The car was only sitting for a year.
