Have you checked for 5V, 12V and ground on all the CPU socket pins as detailed in the build manual?

 

Yes and i have none of those i checked for power at u5 also and that has 0v.

 

So there's no 12V supply into your MS at all?

 

C15 has 12v, mov1 has 12v, d11 has 12v, d10 has 12v, d12 has 0v, c16 has 0v, d9 has 0v, and u5 has 0v.

 

So check all the components that don't have voltage....

 

Im not sure what you mean?

 

You either have a diode in backwards or a faulty part pulling your 5V line to ground. Check all the components you just listed which should have voltage but don't for orientation, then remove them until the 5V line comes up. Obviously removing U5 will stop the 5V line coming up.

 

I check all my diodes banded sides are were they should be.

 

Start checking the components then

 

What should i check for with the componets. Im new at this stuff. =/ sorry.

 

Okay i went and to my best of knowledge im thinking d10 is bad. When i try and get a voltage reading from D10 i only see 12v on one side. The side i see no voltage on is the banded side.

 

Sounds reasonable enough. Try swapping it out

 

should all my black silver band diodes have power on both sides?

 

I changed it out for a new diode no change but if i check for power at sc12 its there but there is no power at sc12c.

 

What is wrong with this POS.

 

One of the above. Go and google for how to test the few components that could be at fault, then do that.

 

Okay i just tested all my diodes and all of them check to be good.

 

If i plug the MS2 into my car and power it up i get power at the MS2 daughter board. So now WTF IM SO SICK OF THIS ******* **** BY THE TIME ILL HAVE GOTTEN A MS THAT WORKS I COULD HAVE GOTTEN AN AEM. WTF

 

Okay very good news i got my MS2 to flash it took some hard finding but turns out my usb to db9 is dead even tho it passed the test. everything on the ecu wroks thanks everyone for the help.

 

winsauce!
