MAP sensor is not reading.
B
last week we were looking at a voltage shift in your MAP sensor when the lights and fan were on. What did you change since then?
Bob
Did you do what I mentioned?
do you have access to the factory shop manual?
The MAP sensor is fed 5 volts and ground from the stock boost gauge. These pass thru that black/clear connector behind the glovebox.
Without a MAP signal, it will not run.
Bob
there must be some electrical issues going on.
