99 Accord No Start, Immobilizer issue??
Bought a 99 Accord LX 2.3 that had been sitting for awhile because it had a blown head gasket, at least that's what I was told was all wrong with it. Had the head resurfaced and when I put it back together I did new timing belts and waterpump while I was there. Double and triple checked all timing marks etc and couldn't get the car to start. Has compression, has spark and I can hear the fuel pump running and I even cracked the line loose at rail and it sprayed fuel. Car will not bust off. Even drained the tank and put fresh gas in it. I've sprayed starter fluid directly into the throttle body and still nothing, it just spins over. Well here is where it gets interesting. The green key light on the dash has worked normal just as it is supposed to the entire time since I've had the car and working on it. I started using a test light to double check power to injectors and fuel pump etc which they did have power and worked as should. Now all of a sudden when I insert the key into the ignition the green key light DOES NOT come on the dash cluster at all, doesnt light up at all, doesn't blink, I mean nothing. Tried cycling the key numerous times and nothing. I went to the local auto parts store and got another main relay hoping that was the issue and swapped it and still nothing. So now I don't get power to the fuel pump or injectors at all bcuz the immobilizer im assuming. I've checked fuses and all seem to be good. Need some help guys as Im out of ideas.

Two things I will throw out there.
Get the e-brake override code for the immobilizer from the dealer - you might have to call a few before they give it to you over the phone.
Next, please recheck the main ground for the PCM - G101. Be sure it is clean and tight, with the head work and that it might have been missed. Pretty sure I have posted pic's of the location of G101 on the 6th gen's before, if you can't find it let me know.
Just me but the "valet" key will start the car....I drive an '07 Pilot as my daily and use it as I don't need/want the one of the other two with all of the buttons.....I've fine with using a key to unlock the door or pressing the button that locks all of the doors when I get out, but I'm a simple person......and what good is a valet key if it won't start the car, they go to park it, it won't start

Where is the main ECM ground located?

Please explain how I ignored? The ECU ground on the side of the intake manifold is hooked up and good. Still trying to get the E brake override code. So in the meantime I'm still trying other solutions. So if you have anymore negativity take that somewhere else. I know why I've lost all power to injectors and pump. The key isn't being recognized and the green key isn't coming on at all on the dash. So that's what I'm trying to get to
