96 Honda Accord

I have just replaced a motor in this car. have checked all grounds and
harness plugs. car cranks but will not run. have checked electrical
system.to injectors have power to injectors but ground side does not
pulse. is there any other things i should check befor replacing the ICM.
the car was running but broke a rod reson for engine replacement.

 

sounds like main relay.

 

Do you have spark at the plugs as you crank?

Ground side of the injectors is pulsed by the ECM, which grounds the
injector lines to turn the injectors on.

The ECM must see that the engine is turning before it will ground the
injectors. The crank angle sensor is the input for that. All the
distributor connections must be good.

As for the Main Relay as suggested by jim, you can look here:

Try pedal-to-the-metal for ten seconds. Engine may be flooded. It's
explained in the owner's manual.

That should read: Try to _start_ it with pedal-to-the-metal for ten
seconds. It worked for me.
