Hi guys, I was having the normal problem from my ignition switch.. I replaced the switch and everything else is working again except for there is no ses light and it just cranks with no start!

 

Some more backround would be great. Did it start before the change with just a bunch of funky problems or was it dead.

 

well it would stall out intermittently but it would start right back up! the other day it died and would not restart! I thought it was the fuel pump cause it was not priming! but then I noticed there was no radio, dummy lights on dash, and it wouldnt come out of park! so I started looking on here and found it was most likely to be the ignition switch.. I put the new switch in and everything is working properly except it will not start.. it cranks just fine and the only thing i can tell is the ses (check engine) light is not on when i turn the key forward!

 

You need to do a passlock relearn

Still spinning my wheels here?

 

Check your wires to the crank and cam position sensor.Also check and see if you got spark from the ignition coil.
