No Start#4, at it again, 2 dmes injectors this time and ground issues

[AMS911]

I have two dmes, Silver lable w/o ews and one is a 413 red labal. I am getting two different problems w/ each ecu.


413 red labal
W/ the red labal, I am not getting the switch ground from the dme to the main relay. If I ground out the brown wire, the relay clicks and the car starts.



Silver w/o ews
My injectors are not firing, I am getting power from the main relay, but no pulse ground to the injectors and no ground to the fuel pump relay. My fuel pump works. I grounded out the injectors one at a time to see if they spray and they do. I then tried to start the car and it fired right up, until the fuel burned off.



What do you guys think? Which ecu should I use?

Thanks Guys

neither, get a known good 413 red label and make sure the car runs on that, then buy it from whoever lends it to you

any one have a good dme for sale?

It was the dme

The red label you have is probably fine you just dont have the harness or Ecu grounded properly.
