I have a 97 civic ex manual trans that will crank but not start. I have done all the tests that TXGREASEMONKEY has answered for other users.(excellent help!) CEL goes out after 2 seconds(does not come on again). Fuel pump hums, relay clicks. Tested spark on all four plugs. OK. Checked MAP, 4.9 volts at + and ground(K-Test). Checked voltage to ICM, 12.8. Installed new fuel filter and checked preasure. OK. All fuses good. Should I replace the ICM? If no good should I then go for the ECM? Please help!
