Car is a 1992 Integra LS with about 71,000 miles on it. I went to the market the other day then came home and parked it. A few hours later had to leave and got in the car and tried to start it but it would crank but not fire. I checked the fuel pump and it is running. I did all the continuity tests on the EFI main relay and it passed all tests. I replaced the ignitor but still no go. I also checked the voltage on the wht/blue and blk/yel wires at the ignitor and I get voltage. I tested the coil and get .8-.9 ohms on the primary winding and around 14,000 ohms on the secondary winding. When I turn the key to the on position the CEL comes on and stays on. The only thing I can think it could be at this point is the ECU. Have I missed something? Any idea if it is the ECU? Also will a P75 ECU work?
