ST185 GT4 Probs

[Bourkey]

I have a 1993 Jap spec 3S-GTE in my 1990 ST185.
Last week it died & I got it towed.
Yesterday I thought I'd sus it out & put in the coil from a ST184 Celica.
It works but the engine will only run at around -10PSI (always in vac anyways).

Could it be the coil or does anyone else know what it could be?
I'm not sure & haven't tested them to see if they're different specs.

There are no error codes & I'm lost at the moment.

how's the turbo itself? does it still spin? could that be why your not making boost?

what 'died' or how did the car behave (to require it to be towed home)? what made you think it was electrical?

coil will be probably near identical, likewise the igniter.

pull inlet pipe off turbo and inspect?

what does engine do when you try to get it onto boost? (e.g. up to and beyond th -10psi barrier)

Turbo is fine.
Suspect electronic fault as engine runs & sounds perfect until you ask for some power.
Coil & igniter are different but not sure if the ST184 coil is causing the ECU to run in limp mode.
Just purchased a coil & dizzy from Ebay so will try another ST185 coil first.
