Code 11 = Momentary power interuption to the ECU. This code will mask all other codes until it is corrected.

Often it's the grounds that attach to the intake manifold.

Somehow, I think so...among others.
The ECU grounds are off the main harness that runs by the intake manifold...if you have them hooked up on the drivers side panel behind the battery, it will be quite the stretch.

(you seriously need to get someone to look at your car that knows what they are doing)

Check ECU for leaking caps or burnt circuit board. Test coolant temp sensor via hynes manual or chiltons. Check and test CPS.

Ey buddy I know your frustrated and all, but please make it easy for us to read. Use some punctuation and grammar please.

Don't cut short on anything and test your parts. Thinking they were working before or new doesn't mean they are not the culprit. Check Fuel pump rely too, as it might be faulty. ( easy test is check for power at the Fuel Pump plug in trunk for power with a multimeter)
