2016 rancher es no spark .7 volts at the pgm-fI from the ckp sensor, Checked grounds and battery voltage to the pgm-fl. Checked relays, ign coil, diodes, battery voltage to the coil, ignition switch, stop switch. Continuity to all mentioned components. Battery voltage to the coil (BL/R). No voltage between the primary connectors at the coil while cranking. Fuel pump and injector cycles fine when the key is turned on. Initially the engine would run for about 7 minutes and shut down, either driving or just sitting in the shop. Since I’ve started working on it I’ve got a no spark condition 100% of the time. Bought a new pgm-fI on eBay (mistake, because the package was open but a 100% seller) The one weird thing is that when the ignition switch is turned on I get two blinks from the check engine light. About 1/2 second each about 2 seconds apart. Not a code to the best of my reasoning. Manual says two seconds ck engine light then the code sequence. Same scenario with both PGM’s. GRRRRRRR!

The ckp voltage is around .7 vac. The book calls for a minimum of . 7. I just checked the ckp voltage on a 2011 that I have and it is over 2 vac. Anyone have any experience with one at minimum voltage?
By all indications bank angle sensor isOK
Ohmed out the CKP and got nada. Open circuit. My 2010 showed 270 ohms. Looks like you are right. Fun fun fun.

Yes. Already looked it over. Stator/CKP one expensive unit

CKP sensor fixed it. Old had no continuity and .7 V AC. New one registered 256 ohms.
