    My Accord started fine one morning, then stalled and would not restart. Checked spark none was available. Had code 15. Replaced Igniter, coil and checked Main relay. No help. Swapped in an A51 ECU in place of an A53. No help. Does the main relay with the resistor drop the Voltage down to 5 VDC before it gets to the ECU. Haynes manual sort of leads me to the Alternator or integrated contrl unit because I dont have the 5 VDC at the Grn Red wire from the ELD. First will an A51 and A53 ECU interchange? Second could I be missing the 5 VDC voltage before it gets to the ECU. Car turns over great, just wont start. Any help would be greatly appreciated.
    Thanks
