So I recently had my PCM replaced since the original one got fried when I installed an Edge Programmer. Now I'm having problems with it starting in the morning or if it's been sitting for more than a few hours. I'll go to start it after it's been sitting and the odometer will show "------" and the theft light will flash rapidly, I'll take out the key and then reinsert it and it'll turn over like nothings wrong. I've never had this problem before in all the years I've had my truck, and I don't feel like dishing out a ton of money just to receive a simple answer. Thanks in advance!

 

Mine was the EEC relay. Cost you $20 to try it.
