unscrew the spark plugs and try to crank the starter
maybe you don't fully turn on the Park? if you press the brake on any gear, how does it start?Have id'd the problem as a bad ground somewhere, occasionally will not start in P but will start in N.
Went thru all connections and tightened everything down will start but again the problem of not starting all the time in P is still there.
then there is a suspicion of the ignition lock and the starter relaydashboard shows correct gear, P or N when starting
what type of lock do you have? button or keys?starter relay has been replaced, ignition lock? is there a way to test it?
it is necessary to remove the lock and try to connect the wires directly, but I do not know your abilities as a mechanic, so it is better to entrust it to professionals if you are not surekeys
not quite like thiswill remove lock and reconnect all wires and make sure I have solid connection, no problem
Hopefully it solves the problem
Thanks
