Thank you so much. Would the car shift out of park? When it wouldn't crank? That's what I'm dealing with on my 08 DTS!!!!!

[@RBTheMechanic]

That’s tough question it should shift out of part of it dosent crank turn the key to acc press brake and try it

[@kevinedwards374]

I have. The tow truck driver couldn't get it to move either. I've check all fuses I can think of. Can it be a security issue?

Mine clicks, all the lights go off and the only way I can get it to start is by bypassing the starter relay. It’ll start for the first half hour once turned off but each day I’m having to do this any recommendations

Replace that relay see the outcome

Not a rip off honestly count and if u consider replacing fuel pump or something else pay $1200. Better find that honest mechanic and pay him for his service. Ur choice
