The same Relay is used in all Japanese 3.0 applications - look for a 90-97 Hyundai Sonata , 92-96 Diamante SOHC,
The relay is like 65 bucks online dealers.

The Module and disc cost like 275. , might as well get the whole Dizzy.
The module , if you haven't seen one is a white chuck of plastic with a disc with tiny slots cut in it. The disc sits between a couple red leds that tell the ecu what's going on with TDC and ? that burn out after about 20 years.
You are supposed to get a code for TDC defect and another code for the other thing the module does...I need some coffee.
Did you take the lid odd the MPI relay???
