Alright. This has been a thing for about a week, now. I have a 1994 EJ1 with a 92 B18A1. I'm running a stock OBD1 P75. I have no spark, and no signal to the injectors/fuel pump. I've tested the ICM as well as the ignition coil, both were fine and should still work. I'm getting power to the distributor, but no spark. I'm getting zero fuel pump signal, and have only managed to get it to prime by bridging a wire from the main relay harness at points 1 and 7 (Fuel pump). I've also bridged points 1 and 5 (ECU?) and was greeted with my oil light as well as SRS light turning on, with my speedometer needle rising to about 20Mph then falling back down to 0. We've tested continuity on the ECU fuse, as well as swapped it out for other ones we know work. Any help is appreciated, I'm dead in the water right now as far as ideas are concerned, about to take it to a shop.

 

 

The proper test is to jump pin 5 to pin 7 in the main relay connector. With the key in ON(II), the fuel pump should run. Does it?

 

After bridging pins 5 and 7, key in ON(II), no fuel pump whirring. CEL stays on, no FP priming happening there. What's this mean? What is pin 5? I know 7 is the FP. What's being tested with that?

 

Check whether 15A dash fuse 24 is blown.

 

Okay, we got the car to fire up a few times, got the fuel pump to prime by bridging a wire from pin 7 to the constant on my ignition terminal (black/yellow), tried a different distributor for the sake of testing, she fires up. Swap the other dizzy back in, doesn't work. Problem with the dizzy that worked, is that the mounting tabs don't line up at all, something about it being a GSR dizzy, had a friend hold it while we fired it up, and it worked. So I'm thinking the distributor is causing me problems. Also found a very janky cut and resoldered power wire to the main relay, which we've now cut and butted properly. 15A fuse popped, not sure if it was from bridging 5 to 7 or cuz my buddy accidentally bridged ground to power. At the moment the only way the fuel pump will prime is with the previously stated method above, not sure what that means.

 

Also, I'm pulling codes 9, 15, 20, and 41. I have no O2 sensor so I could care less about 41 but 15 and 20 are new codes as of starting the car up those couple of times.

 

Why didn't you check fuse 24 and replace it if it was blown?
