Hi all i need help with my 2004 toyota avalon. I had to put a used Engine in this car becouse i droped a bolt into on of the cylinders. The problem i am having now is that it will crank but will not start. I cannot communicate with the pcm i have one bad ground that i tested at the pcm. I need to know if i am looking at the write spot.

Do you guys not is i need to reflash the pcm becouse i read on Prodemand that is the trans has been replaced witch it has you may need to reflash the pcm. I had this thing running and i needed to put a new belt on it so i did and after that the car would not start. It will crank but will not start. If you guys have any ideas on ware i should look at let me know
