The nose switch needs to be pressed in order to send the signal to the computer to idle. Make sure it's extending out till the switch is pressed. I'm not sure how to test the switch but it should be on here somewhere. Shaft seals get dry and stiff preventing a good seal. They should be changed if they are the originals.

Have you tested the isc for proper function? I took mine apart to clean out the old grease and apply some model train grease. It wasn't working smoothly and sometimes would pause before reaching the idle position to signal the computer. It turned out to be a wire in the isc not making good contact. If I remember correctly, it broke off at the solder joint inside the isc. Vacuum leak? Did you change the throttle shaft seals? Maybe damage to the throttle shaft seals during the cleaning if not new.

Did you cut and solder one wire at a time on the injector clips? Put everything back to stock as it was before you took it apart and start from there. I can't remember if it's the same as the 87 but you need to reset the isc with the car not running. The isc needs to relearn the idle position. I've done it to my 87 but that was a long time ago.

What hit? 🤷‍♂️ Looks good from here!

Welcome and congratulations on your find! Head gasket failure and cracked head are common unfortunately. Upgrade the cooling system with an alum radiator and eliminate the jet valves. You need to drop the gas tank if it wasn't drained when it was stored. If so, replace the fuel pump with a walboro pump. That's just for starters!!! More pictures please!

Was this just for s**** and giggles or are you really looking into a full rebuild over a blown head gasket? X2 what @techboy suggested. To add to cylinder head inspection, look for any hairline cracks in between valves and sparkplug holes.

I have one of those cassettes! Came with the original owners manual and cover for my 87 Starion. Not for sale though. I do remember hearing the audio online somewhere. Edit: Found it.

Sometimes it's the simplest things that get you. Perseverance will pay off.

Man, I almost had a panic attack just reading... but then it worked out for you...

Man, just reading your post gives me anxiety!! You're a brave man taking on such a project by yourself.... Brave or crazy as our significant other might say... But as long as it doesn't pass your elbows!! Lol. Onward

I don't know which radiator v8 swappers use but alum radiator helps with the cooling. I know 20 yrs ago Griffin made the only alum radiator that bolted up like stock. Someone with v8 swap experience will chime in. Any pictures of your v8 engine bay?

If the positive cable was touching the chassis then more than likely somethings fried. Links, fuses, switches, relays, computer and wires. I know you tested some of these already but deserve a second look. On my 87 the alarm would turn off/on by turning the key to lock/open the door and holding the key turned till the alarm engages/disengages.

How to cast a snake would be a more popular thing to cast. People use some type of dough or silicone to make a mold and then pour the material of your choice for the part. Lots of videos on the tube on how to cast at home.

What value???? Lol Any changes from stock can hurt the value. These cars came with some cool cloth interior too but the majority seen are leather. Stock Tan and black interior is my favorite .

You can always cast/print your own. You would have to do research but it can be done. Don't throw any of your old parts.
