it's not that the coils are firing, its the the MS still isn't getting the RPM signal inputted correctly yet.

go to the diagnosis tab, and capture the composite log. Crank for about 10-15 so you get something to show up. Screenshot the results.

doens't look like it's getting your Crank signal.

this is the green and purple wires on that document of mine. your black/white wire to XG1, in your picture it doesn't look installed, is that going to the correct place?

The resistor on r12 you replaced is 470ohms?

R12 is 470 ohms
My black and white wire is connected correctly .(tachselect to xg1, c30 to 5v)


Is the 5v at the top of the proto area need to connect from Iac1a?

you conntect 5v through a 470 to js10, and iac1a goes directly to js10.

but it seems youre getting that input, its the main crank youre not getting.

Yes . Loaded your MSq , disabled the boost control, did the calibration, all the error message gone, crank it, the ' not cranking ' indicator stay.
And not firing

The resistor from js10 to 5v is only 450ohms . Will this cause problem?

no. its just a pullup, that's fine.

since you have the Green inpu ton your composite log, it appears the JS10 input is good.

It's the blue signal youre missing, which is the crank, and that comes in the tachselect to XG1 circuit.
