I installed the Gen II and LT1 Maf sensor per instructions, reset the ECM and the car was hard to start, I got it started and drove about 15 miles, the car drove great, I got back to the house shut it off and went to start it 2 minutes later and nothing no crank at all, totally dead, checked battery 13 volts, do you have any ideas what could be the problem?
Thanks
