    No start 91 Civic
    1991 Honda Civiv dual point injection system. No start

    Have checked the following. Main relay, test OK with 3 clicks. Has spark. Swaped Computer. Suspect no power to injectors since system has fuel pressure. Intake is dry.
    Don't have a noid light to verify power to injectors. If no power to injectors, what would be the next step. Thanks in advance for any info. Tim

    . Check all under-dash and under-hood fuses with a test light or multimeter.
    . Check for codes; e.g. Code 16.
    . Read sections A and B below:

    Have checked all fuses > good. No error codes are logged since I just did an engine swap and system had no power for days. Next step?

    Try cranking engine for 10 seconds - this should be long enough to set a code. The dual point injection runs the fuel pump and 12v+ to the injectors on the same line. If main relay is bad (or injector resistance) you will get a code 16. -->replace main relay

    If no code, take a long flathead screwdriver and touch it on to the metal housing of the injectors and tap the screwdriver with a hammer a few times to jolt the pintles free. Since you indicated you swapped the engine, your injectors may be stuck. I've seen that many times on junkyard engines.

    Do you have spark?
