42 is clear as day, all the time the ECU wanted to tell you what was dead, how about that.!
i means 1 in 10 pulses from the CMP are missing, or ALL OF THEM. (dead)
nice PO, not.
so, make sure the grounds are not bad at the xxxxx oops no year or engine stated
use a signature or profile to tell helpers what you have.
all this is easy stuff.
on the 8v those ground wires on the DIZZY mount are not for fun, they are key in the ECU ground systems
and the dizzy almost never fails the CMP, unless the grounds are bad or the side connector is loose or corroded.
92 8v.
i read the whole post its and 8v. with only 1 injector
so read my bad grounds.
here.
G105 ground? bad?

read my CMP test , on my no spark page, (i really have no spark it says) then.
the cmp can be tested 3 ways, (scope, meter and LED lamp)
http://www.fixkick.com/IGN_timing/no-spa...CK_:_89-95
the best meter to uses is a 10 buck walfart analog needle meter. and one leather sewing needle for back probing on car.
most easy and no making tools, or $100 boat anchor scopes.
the FSM covers that why, fully (meter set to 20vdc, and test lead black to ground and white dizzy wire backprobed (do not unconnect the dizzy or it will be dead)
but here is a video with a LED (dizzy out of car)
a 12vdc battery
and LED.

and see it flash.

or connect the voltmeter to the white pin, on the Dizzy connnector, back probed with sewing needle.
and see the needle (meter needle) wag 0v ,5v, 0v, as you crank engine.
