The interlock system on my '90 Integra is intermittent, but it only shuts off every once and a while. Maybe once a week it won't start, so I wiggle the shifter, put it back in neutral....maybe push the clutch a couple times and it starts, or maybe after doing this a couple times.

I've pulled the connectors and tested them and the switches on the clutch pedal. Of course it's not usual that this occurs so it's going to be very hard to find the real problem without randomly replacing parts.

Plus, getting at some of the switches means taking a lot of stuff apart. I'm getting ready to make a 1500 mile trip and that worries me. It might just quit when I'm a long way from home.

I'd like to have a way to bypass the system if need be, during the trip to get me home. My Acura Integra shop manual seems to only show A/T interlock wiring.

Anybody got any ideas on how to bypass this system?

Thanks!

On a manual the only type of "interlock" is the clutch switch underneath the clutch pedal. Sounds like you have a bad connection in that system somewhere. To bypass it you can simply ground out the circuit.

I thought about that, but it's got a switch at the top and bottom of the clutch stroke. So I postulated it might be more complex. There is an interlock relay, I found that too when I had the lower dash apart. Jumping that or unplugging it has no effect, but you're saying ground it to frame/engine, not jump it or close the circuit. I wonder though, if then there might be a problem with the engine management thinking the clutch is always depressed.
