This is a tough one. let me start with this. H22A4 obd2 on a civic ex harness. into EJ.
dropped the motor in...
all went well. tried to fire, no go. so i started in with the Fluke, found that there was no spark, then found that there was no signal coming out of the dizzy to make spark. im almost 100% that the CYP TDC CPS CKP, and other dizzy wires. all have power where the should key on or key off.
so when im cranking over the car, no signal is coming out of the grn (primary out put control).
So i try putting in a p28 with my old D series map on it, and bang now i have spark. WTF. im sure this p5m ecu is good, i watched it drive a prelude just the other day.
so my only guess is that a wire is wrong, but look and they are all right, i don't know whats up. anyone have any ideas, i really don't want to run a p28. my chip burner is busted and i can get a good map on a chip.
PLEASE PLEASE i know there are some smart *** HT members. any input thanks.

Looks like a immobilizer problem. What car did you check it on? The car it was original from?

the ecu? the car was wrecked from the rear, he drove it into the shop beforee i pulled the motor from it. so the ecu was in the car from factory. i took real good care of it, never droped it or anything

yes, but they had a immobilizer, if you do not have the key from the car, the ECU will not work. It is anti-thief

ah, so it will crank over but no start?

how do i go about to fix that?

You have to do a hardware mod. I believe they have used the same hardware as a ITR ECU, I have never done one.

or, if you have a 96-98 civic, get a 96 prelude VTEC ECU.
