Car will not crank over??????????
Parked car came back to start heard all the usual fuel pump and releys clicking then tryed to start and nothing no cranking at all. No codes. Checked all fuses and relays seem fine. Ignition switch is good. When i put to start position i get 12 volts to the yellow wire. I think it might be serurity system. How can i check this is. Is there a relay? Tryed to disconnect battery still nothing. Tryed back up key ,same no cranking. Any help would be great.

Pull the codes and post them. Include the H or C or HC that follow the codes:

O.K. Checked both key resistors and their 522 omhs which is correct tryed the relearn didn't help.
Is there anyway to check if ingition switch is bad. When i turn the key i get 522omhs at the two wire that gos to bcm. So seems like ingition switcg is ok.

No codes. I cleared codes yesterday and tryed to start car right now and nothing. Checked codes nothing again. My pull key wait 10 sec comes on which hasen't done that since i put the bypass in and removed that nipple that holds the steering wheel from turing you helped me with that a few moons ago.
