My honda will not show any indicator lights on the ecu, i bought a new ecu and im still showing no indicator lights. i took off the distributer, and changed that brown relay(ignitor maybe?), same thing, the check engine light stays on, i do not hear the fuel pump, i do hear the main relay click. i am getting power to the computer, and ive tried 3 different distributers..i also have no headlights, but i do have side markers and hazards, the car is a birthday present for my girlfriend, rims body kit the whole jazz.. PLEASE HELP!Thanks in Advance !!!

First, try jumping terminals 5 and 7 going to the main relay connector, to confirm the fuel pump works. If the fuel pump runs, then I would replace the PGM-FI Main Relay. I normally recommend replacing them every 10 years or 120,000 miles, whichever comes first. They are a very problematic (and important) component.

Now that the CEL comes on and then goes out, check for codes.

Yes.

so did i snag another dead end? i still dont have the fuel pump, but i sounds like she wants to go

Remember to always disconnect the neg. battery terminal before working on the electrical system, particularly when swapping out the ECM.

Again, I think the next step is to remove the main relay and confirm that the fuel pump runs, when terminals 5 and 7 are jumped. If it does, then I would replace the relay.

No, I don't think you snagged a dead end. I think you are close to victory.

Here's a simple but sometimes important step. Remove and clean the main ECM ground on the thermostat housing. It's a 3-wire brass connector.

THERE'S STILL THE POSSIBILITY THAT YOU HAVE ANOTHER BAD FUSE; E.G., THE 7.5 A STARTER SIGNAL FUSE. That's why you need to test all under-dash and under-hood fuses with a test light or multimeter!
