Hey guys so as some of you know Im doing an engine swap in my 87 GT Automatic. I got it all hooked up and its ready to fire up but I got a problem
Ok so I bought a new starter new Alternator all new sensors all new ignition parts. When I turn the key I get dash lights and my head lights work. I can hear the fuel pump prime and then stop like normal. When I turn the key to start, I dont hear the starter click, engine doesn't crank, My lights don't dime and my battery has a full charge on it. Just no click from the starter and no crank. Gauges do move when I try to start it. The speedo, fuel gauge and voltage gauge all twitch a little. The Temp Gauge moves from the low side all the way to the high side, if I let up on the key the needle stops and if I hold the key down to start the needle goes all the way past max temp. Not sure if that helps. I checked all my grounds and as far as I can tell every one is good. Wires on the starter are hooked up right and are tight.
I am going to bypass the starter wire tomorrow and make sure the solenoid is working. But if you guys have any other places to look, let me know.
Any chance you swapped harnesses? The AT and MT harnesses put the starter wire in different positions on C500.
Use a 12v test light. When the key is turned to start do you get +12v on the large yellow wire of the AT transmission plug? You should
Is the AT in Park? Is the AT connector not plugged in? When the connector is plugged in the +12v on the yellow wire when you turn the key to start is passed on to the purple wire that then runs to the starter solenoid.

Problem is I only have one harness, the engine I rebuilt was just the block and intake no sensors or wires. So how can i tell, Should I just switch the yellow wire from A4 to E2? I will double check the AT sensor tomorrow.
also this just may be me over thinking or not knowing enough about Fiero's. but if the car is an 87 and im using the same Wiring harness that was in it, do i need to change any wires in C500? Shouldnt it still be the same as when the car was running? I only changed engine years, from an 87 2.8L to a rebuilt 86 2.8L or is it maybe I have a bad wire in the starter circuit?
I just tested the AT Large Yellow wire and Purple Wire. With the key held to start I got 0.020 Volts when i let up on the key it goes to 0.015 volts.
I took a wire and hooked it up to the Positive Battery terminal and then touched the starter solenoid. It kicks over like it should. I can't see anything wrong with any of the wires from the starter to the Battery. I also went through all the gears trying to start the car in case the gear shifter was not in the correct gear, no go there either. I don't think its the whole C500 switching wires around deal due to the fact that the car is and 87 and the harness I have belongs to that car. i.e. the wires should be in the correct spots on C500, Atleast the engine that the 87GT came with worked with that harness.
So Im at a loss. I dont know what else to do here, could really use some guidance.
Bad Neutral Safety Switch. I double checked the linkage to make sure it was adjusted properly, It was Still wouldn't start. Unplugged the NSS and jumped the yellow and purple wires together. Car started.
Thanks to everyone for the help. I hope I want have to post back here for any more issues.
