Calling all st205 swapers, Need help "Lets get her done!" Options

[lantz2121]

Your favorite, Well I have been in the process of this resto swap for 2 years and i want it done in the next 2 months. I have a 96 st205 engine into a 94 st. I have the 205 harness plugged into the st body harness; It will not turn over tried replacing the st reley nothing. Have you done a 205 to st chassis? I have the harness installed on the engine and the engine is in the car, so i really do not want to take it off. I thought that the same generation engines would be plug and play with some minor wiring. I have a gt ea1 diagram but I can't find one for the 205; i am assuming that the problem is in this plug. I have also assumed that the 205 plugs on the ecu side would be the same as the st on the body side behind the climate control. if youy have any info or another person who has done this swap please let me know. any and all help is greatly appriciated.

I need some help from anyone that has done a st205 engine into an st. If anyone is in the central ohio area I have lots of beer and i know quite a bit, but wiring is my weakest link i need someone to tell me where to start looking thanks lance.

I'm assuming you are putting a RHD ST205 motor in tyour LHD '94 ST? There are a fair amount of wiring differences between LHD and RHD in the dash harness area. That may be your problem. Time to start tracing the problem.

When the key is in the 'off' position, does the correct ECU pin get power?
When you turn the key to the 'on' position, do the correct ECU pins get power?
Does the 'STA' signal get to the ECU? Is the fuel pump priming?
When you turn the key, is power getting to the starter?

We don't have enough info from here to actually help you out though - you gotta start trying things and let us know what you found to be wrong so we can help you fix it.
