I just got a MP-8 in the mail today, got everything plugged up and the truck wouldn't start. I unplugged the connectors and hooked the stock connectors back up and it started. I then hooked up just the map sensor connector from the MP-8 with he stock fuel sensor connector and it started. I then plugged the fuel connector up from the MP-8 and no start. Has anybody had this problem before or any suggestions?
