Bypassing ECU power source?

[Blacketik]

Hi,

I just want to bypass the power source for my ECU. The problem is that my ECU no more get power. I have 1 MSpnp for 96, and 1 stock ecu 96 and both are not able to power up (no check engine light for 2 sec when I turn the key to on and the car don't start no fuel no spark (no ECU ...)).

If I try a lot of time (maybe 100times), I will get power, and the car will start without problem. But is very anoising, so, can someone confirm that I can bypass the power source, and also, show me where to put the power on the ecu pinout?

Here is a link for the ecu pinout (probe 96, but I think it's the same).

You should be able to hook the ECU up to any power source that gets power when the key is turned to the ON or ACC position. I believe the sunroof and windows work this way, as well as the radio. Just make sure you wire it properly so you can still tune the car while it's not actually turned on.

Ok thx, can I also bypass all the ground?

I am not sure about the grounds. My EMS system and most others run off grounds so I would be careful about what you move.

Just to tell you that my megasquirt and ecu are now working! I got 11.8v vs before power was only 11.6v, now everything work good!
