Okay so ive gone through 3 ecu's now 3 man relays and a **** load of fuses...
just a brief description of what happened...i was driving my crx (90 dx w/ mini me) in a parking lot a few weeks ago
and out of nowhere it just died...first thought was i killed it but i was wrong...tried pop starting it with a few guys like 10 times and it would just bog down
i checked all fuses then and all were good....then i pulled back the carpet to see the ecu and turn the key to off and turned it back over to have all the power on and whever i did this in the past the led on the ecu would blink once meaning ecu was powered....well when i tried the led did not blink or anything...so i checked the ecu fuse and it was good...
later on in the week i bought a new relay and still nothing.....ive gone through 3 of those and 3 ecu's and the ecu still wont get power so my car wont start....

does anybody know what the problem could be...any advice..anything???
i need my car as i have been out of transportation for 3 weeks now...
PLEASE HELP!?!?!?!?

 

does anyone know which wire is the power wire for the ecu??

 

The Honda typical ECU ground wire is out at the thermostat housing, clean it up and see what you get, dont you have a manual and a volt meter.

 

yeah i already knew the ground wire...i need to find the power wire going into the ecu
and no i dont have a manual...
and most of my tools i had to leave in NM when i moved

 

the 2 yellow/black wires going into the "A" (green one) plug are the power wires for the ECU from the main relay.

 

There has to be more power wires than from the main relay, what about memory.

 

what about the ignition switch..

 

i know this is kinda a dumb question but did you check the fuses under the hood?

 

the constant battery power power or "memory" wire is pin B1. Its white/green

 

yes i did check fuses and all that other stuff
i ended up narrowing it donw to both of the yellow/black wires on the biggest plug....i believe A
and sure enough the ecu started working again after i ran a wire from a power source to those wires...
now i have a diff problem....it runs like **** ill shoot a video when i get off this afternoon and let you guys hear how it sounds
