i just did the swap and it will turn over but will not start. the check engine light stays on and when i try and get the code the light does not do anything it just stays on. i have spark and i am getting fuel. anybody might have an answer let me know. i have been throught the wiring a hundred times. also when i hook up the f22 ecu and turn the key on the check engine light goes out after the fuel has pressureized. like it did be for the swap. why does the h22 ecu light stay on. am i correct in that means i have a problem and need to veck for a code?

 

yes, if the CEL comes on check the code

could be bad ecu?
