ok here's the story. picked up a minty 91 hatch shell to replace my haggard rusty 90 hatch. it was auto and dpfi. so i pulled changed whole body harness and dash harness from the donor car. donor car was running and had already been converted to mpfi and obd1. i have no spark, no injector pulse, no power at injector resistor box. the fuel pump primes like normal and cel comes on and goes off like always. no codes, also no 5v at tps but i do have 5v at map sensor...... gonna check grounds tonight on ecu. according to the diagram on alldata the same yelllow and black output wire that powers the fuel pump also powers injector resistor box. so im kinda stumped there. any help is greatly appreciated thanks
