[QUOTE="Flyer58, post: 436557, member: 18629"] Ok throttle body injection? This is getting outside my line of knowledge which is limited to my '92 2.5L. I think the ECU might be under the dash. If it's fuel injected I believe there should be a coolant temp sensor and typically that's the one in the front like your picture shows. I found this wiring diagram in the Factory Service Manual which shows the sensor in the 1990 model. Link in our Reference section of this forum...
