Anyone ever come across a scanmaster 2.0 that will show all data when ignition is on, but only dashes when running? New problem I have after swapping coil pack to type II but shouldn’t matter. Is there an inbetween that causes this glitch? It will just show 2.0 then dashes which means not reading. So, why read just prior to starting?

Did you change the 12V power source, and do you know what the voltage is at the power source?

No, I didn’t change anything like that. It reads 11.7 volts ignition on, and when running, I was getting 13 volts on my fuel pump. Weird that the jump from ignition on to start disrupts it.

The problem started after you swapped to Type 2. Swap back if possible and report back. I'd wonder why you swapped to Type 2 when the stock junk works fine.
