tried to start this morning and i notice the d4 light is acting strange, usually i turn the key to the on position, then d4 and check engine light flashes then turns off(this point you can hear fuel priming) and the car will start. Now i turn the key and d4 does not light up fuel pump doesnt prime and check engine stay on whole time, when i wiggle the gear shifter(a/t) the d4 light will flash and the check engine light comes off... What is loose or what is the problem is it the (a/t) gear position sensor? Car is not starting anymore only cranks
