Heres the short version. I recently put a b18b1 motor into my ek coupe. Obd1 motor to obd2 car.. So its been running for like 2 weeks. And everytime I turn on the car it takes a little bit longer to start up. And once it turns on it revs between 2000 and 2500rpms. then slowly it goes down till it eventually get to 1000. So today a couple minutes ago I went to grab some food and when I tried to turn on my car it wouldnt start. So i kept trying it. Till it finally turned on. When I was driving backhome my rpm gauge started flipping out while I was in 3rd gear 4th the same and 5th aswell. I dont know what happened then it just suddenly stopped working. After when I pressed on the gas it did have the same potential it had from b4. so I drove it all the way home. When i turned off my car i tried to turn it back on an this time it wouldnt start back up. If anyone knows what the problem might be pls let me know. Maybe what things to check. Well ill be waiting Thanx!

Im using an obd1 p75 ecu. The motor was dropped in with a d16y8 wire harness. I used a obd2a crossover and also put an obd2 dizzy and alt. LMK if you guys need more info.
