I have a POS 86 XT MPFI non turbo at work right now. The two relays on the left side behind the stereo at clicking when I rev the engine up. I pulled all the trim and everything out so I can get to all the wires. Problem is with the relay with the black connector and the one with the brown connector. I figure they are Ignition relay and Fuel pump relay. They have a black with white striped wire jumping between the two relays. It looks factory so I think thats the way its supposed to be. Now the car wont stay running at an idle. And when I rev the engine up the clicking happens more often (from the brown connector relay) And when the clicking happens the ECS light flashes on for about a 1/2 second.

 

I have both haynes and chiltons manuals on subarus and they dont really have the right diagrams for the 86 XT non turbo.

 

Anyone have any ideas on how to fix this thing, please let me know.

bump....

One thing that I have found helps alot with some of the lesser known cars is to get a subscription to http://www.alldatadiy.com

This allows you to pick the specific make and model and get access to all the TSB and wiring stuff.

It is 24.95 for the first one and 14.95 for any additional ones so I try to keep at least one going. I have 14 going right now because of the number of different car that I end up working on. I am about the only mechanic in the whole area.

Ps they do list 86 xt (2wd) and

86 xt (4wd)

Alright - thats a long term solution I'll have to look into it for future work.

 

I'm wondering if the previous owner has the coil hooked up wrong? it seems like the coil sparking to the ECU would make the fuel pump relay click like it does..
