then it sounds like you have an ingnition switch issue. not sending a call signal to the relays when you turn the key

you have bypassed the inerta switch, relays are good, ignition switch makes the relays "hot" .. sounds like the ground switch in the ECU has gone out....

you can work around that,, rewire the relays so they actavate when the key is ttwisted.

I had the same problem yesterday. Turned out it was a ground wire that went to the negative battery terminal. I also have an 88 2.3, on mine the wire came from the terminal, went a few inches and then there was a plug. A wire came out the other end of the plug and went into the wiring harness. make sure its getting a good connection. mine was attached but just not connecting. hope that helps you out.
