04 civic 1.7 auto I replaced ecu and emmobilezer car still no start no fuel pump noise help

 

Was the ECU and immobilizer a set that came together?
Or were they separate units from different places?
Also, did you get the key for the immobilizer?


There is very little detail and so there is no way to know what is going on

 

Yes both ecu and immobilizer together and key and car still no start also no check light before start and no immobilezer green key berfore start too in Hawai’i it’s a little hard to get parts I had to order from Cali anything would help thanks

 

No check engine light?
If no check engine light then no power to the ECU??
Makes it sound like the ECU may not be the right one for your vehicle??
May be a harness ECU mis-match??

 

I have matched the part #its plm a72 I don’t know what else to do fuses ok also new relays in back of glove box it was doing this with old ecu and immobilezer so I replace it something is happen

 

Are the fuses getting power?
Did you do a visual or electrical check of fuses?
Sorry, something is just not right.
No check engine light means the ECU is not getting power
If this happened before with original then would suspect wiring issue
This is beyond me, sorry no help.

 

Did both test thanks for advise
