I couldnt get on here from my phone to reply, I dont even know where to start with everything you said in the top post except the service manual do you have a link to the manual?
It is not flooded that seems to be the go to response with most people here although it is a common cause for a no start the plugs are dry no smell of gas etc and we have tried the hold the pedal down trick to clear it.
Basically we turn the key dash lights headlights everything comes on turn the key up to start position and it doesnt do anything. We tried everything we could think of to try to start it.
As far as the obd port i have one of the cheap ones that plugs in i did plug it in and turned the key and it didnt come on not sure if it even works. i will plug it into a different vehicle to see in a little while.
Im not sure what my brother in law crossed exactly because he was the one that had his head under the front of the car doing that with the wrench.
I just know he crossed the terminals while i had the key in the run position and it would turn over but wouldnt fire .
I listed everything we tried in order for someone to see what we checked.
when we turned it over by this method and it wasnt firing we checked the fuel line to ensure it was definately getting fuel to the fuel rail which it was. then we pulled a spark plug and tried turning it over and watched the plug and did not see a spark.
If you have a link to the manual that would be helpful.
