checked all fuses and the ECU relay and still nothing. so I'm either going to replace the TCM or the ECU next. will let you know it either one of these work.

Questions???? I didn't see an answer. Is the check engine light on when you put the key in and turn to the on position? Does the car turn over but not start?

Never mind, I see it's a 2003.

yes the check engine light is on and no the car does not turn over and what do you mean by "its a 2003"?

I thought it was a 2005. when my car was not cranking I could start it by grounding out a wire in the underhood fuse box. Since your check engine light is on I doubt it's the same issue. I was losing power to a couple hot wires on the ECM but once I grounded the wire out it would crank up. Different engines in our cars.

Had same problem. Towed to the dealer they gave me a new key, said the chip in the key had went out! Never even knew the key had a chip in it
