Hey guys. Thanks in advance for any help on the matter. I just need confirmation on my diagnosis but open to other possibilities. so here’s the skinny.
91 ls integra sedan, I am a da/db enthusiast and have two of these cars I recently just got this db back up and running after she sat with a grenaded engine for about a year. (friend hydrolocked her trying to seafoam it with me. worst day ever.) I bought a third da last year for my other half but things happened and long story short car ended up mine. it had a b18b swap in it but the body was shot as I live in Vermont. I pulled that motor and swapped it into my db a little over a month ago and did a auto/manual conversion, to what I believe to have been the correct way. innovative swap mount obd1 dizzy, converted fan switch, and all the wiring involved I followed using the diy on here.
so heres the problem, ive been driving the car as it is unfortunately for now my winter daily as I put my da up for the winter and on my way home tonight, not even a mile from my apartment, I noticed my tach drop to zero instantly I immediately pushed the clutch in thinking the timing belt had snapped for some mystic reason (as I just changed it) but noticed the car was still idling. I got in my yard and found that the temp gauge also had dropped to zero, my cel light doesn’t come on, (it has been coming on for the egr as im still running off the auto ecu) my oil pressure light doesn’t light, my seatbelt warning light doesn’t come on, defrost doesn’t work and seatbelts wont retract now. the light/key in ign chime also doesn’t work though it barely did before because of the door switch.
I believe its the icu though I replaced it once already for the random beep/no defrost/ int wiper problem theyre most common for. however im worried its not just that because I don’t know all of what the icu controls. it doesn’t make sense for it to have anything to do with the gauge cluster. im going to check my grounds tomorrow, however its 26 degrees here and I have to use the car to get anywhere. im strapped for cash and at a loss for any other possibilities. any input is greatly appreciated. please.
thank you again.
