all non essential systems do not receive 12volts while the key is turned to start to aid in cranking, so don't worry about boost controller or stereo.
If it cranks then you need three things Air, spark, and fuel.
-Pull the plugs and make sure they are not fouled. If they are good then check that you are getting spark from each coil.
-Fuel. If its getting fuel then you will smell it from the exhaust. crank it a few times and then stick your nose at the muffler to check for fuel.
-Air, if you have spark and fuel then check the intakes/manifolds for leaks and the intake-tract for obstructions.

What would symptoms be for a bad ignition switch? This is killing me ! It's drops volts bad while cranking down to 6volts, I've checked the terminals ,from the fuse boxes to the battery alternator , starter they all look good and clean no corrosion
I have duel pumps in the back , I hear them cycle with the key on, could one be bad and draw the voltage to drop ? I got pressure upfront on fpr ? More advice on please thanks
