Car Starts! Dies after 3 sec

[jsmcortina]

For reference the MS1/Extra code sends SAW during cranking and this appears to work fine.

The first two SAWs include the multispark arming code too if multi-spark is enabled.

Thanks Al. I performed 2 cold starts & many hot starts.
Using calculated solved the stalling problem!
Crank times continue to be long.
I have tried warm starting PW of 2,3,4,5,6,7,8, & 10.
2 is too lean & 10 is too rich. The others all have long crank times.
I reduced the skip pulse to the minimum of 3.
How many revolutions does it take before a cylinder gets spark?
Have any suggestion to reduce crank time?

It should start sparking after 2 or 3 tach pulses (meaning < 1 rev for 8 cyl or 1.5 revs for 4 cyle). With EDIS it may be even sooner.

To improve starting time first thing is to put a timing light on while cranking and observe that the timing is around 10 deg btdc or is at least reasonable for starting. You can also observe whether the timing light fires right away and whether it is steady or goes on and off and if it is steady or jumps all over in timing.

You can also try changing the following variables:

Use Last Interval prediction if you aren't already
Increase the Pulse Tolerance during starting
Change Prime Pulse
Change cranking speed
