3rd time now(in ~30 days), gone out to my Jeep and it wouldn't fire right away just cranked.
1st 2 times it eventually started after cranking for a really long time.

Could smell fuel, and gauge reading normal while pump running.
So, checked wiring, pull the coil wire and cranked it...no spark.
Checked wiring again and cranked it one orange spark then nothing.
Annoyed I smacked the MSD 6A box and tried again...spark returned.

So, appears the box is on the way out. Been a good run bought it for $50 14 years ago.
I'd bet money I've had it installed in ~4 different vehicles w/o a single issue until now.

On to my question. Is the new MSD 6201 box going to work on a 1227747 fuel only system?
Same tach signal output as older 6200 box?
Or is there another ignition box maybe cheaper that I could use?
Distributor is Motorcraft Duraspark style 2-wire pickup.

Due to CA smog, I cannot switch to standard GM TBI ESC module, have to keep it fuel only.
