i installed my msd 3 bar yesterday and the car did not want to give any fuel wat so ever .. i had a stock map on 10lbs and i wanted to do 13lbs. i swapped it back to the stock map ..i did switch it on the hondata to the 3 bar but could it be that it was getting to much volts? i think it was getting near 7 vlts so should i put it back on there and change the voltage down to like 5?

 

Double check your wiring, also check the part number on your map sensor to ensure it is the correct one.
