I am not getting any injector pulse.
When I put a noid light on the injector harnes the light only comes on once when I initialy crank the engine and never comes back again. Fuel is at the fuel injectors and spark is available to all spark plugs.

What could be a problem?

Most likely the crank sensor inside Dist. If PCM does not receive crank motion it shuts inj. off. Crank should Ohm out 600-950 ohms

I replaced the distributor and still the same simptom comes up, one pulse from injectors and never again. this is a 91 integra but has a distributor from a 92 and the connectors are not the same. the connectors have been switched over by the previous owner. i have looked to make sure it is wired properly and everythin looks fine. what else could be the problem. I have also replaced the ecu and main relay and still nothing.
