So i just bought an RS that the owner thought the ECU was fried in after he tried to install an EMS.

I just rewired the ECU harness back to stock and decided to try to start the car anyways.

When i turn the key to on, there is no CEL. I switched the bulbs and still no CEL.

Also the fuel pump doesnt prime at all...

I turn the key and the engine cranks but does not start.

I checked the fuses, and swapped (what i thought was) the fuel pump relay with an identical relay next to it.

Is there any other possible solutions besides the ECU being fried?

I havent checked to see if im getting a spark or not.

thanks

yup sounds like the ecu

no CEL is a pretty good sign of that.

Did you check to see if the ECU is getting power?

So i got my new ECU today, and the car acted the same way.

Still no CEL or fuel...

Im thinking that the ECU is not getting power.

Is there a fuse for the ECU?

Does anyone have the repair manual for the 00 RS? I only need the wiring section

Check your grounds and the engine harness connectors under the hood. I had weirdo electrical problems because of a dirty connector to the engine grounds.
