Looking for some help

Last Saturday the engine failed to start, had to use the kicker to get back to the marina.

Started engine and was letting it warm up while I was putting away the trolling motor and gear when the engine quit, tried restarting but no go, check fuel primer bulb and it was rock hard, removed both ends and checked to make sure check valves were not stuck. When back on shore removed fuel filter and drained, no signs of water visable, tried starting and after 5 - 10 seconds cranking the engine started backfiring through the exhaust. After getting back home I hooked up the computer software version 1.4 checked for codes, none alarmed, checks CP sensor, ohms at 1016, good according to service manual, checked timing while cranking 12 degrees BTDC, checked compression, same as last fall, low on port bank (1- 99, 2- 99, 3 - 87) and good on starboard bank (1 - 116, 2 - 119, 3 - 115), plugs look to be good, test fired all injectors, OK, test fired all spark plugs, OK, going to change out spark plugs and see if that the problem but I'm lost for any other checks, any help would be appreciated that I can check on my own before I take the 3 hour drive to the nearest Evinrude Tech.
Thanks in advance
heres a copy of the emm report, note intermittent code are from years previous, i have never cleared them.

I will check all fuses tonight, as far as popping noise goes coming from the exhaust through the prop it has enough force to blow the gravel around from the parking lot, I would say the cylinders would load up with unburnt fuel after crancking for 5 or more seconds and eventually ignite the raw fuel built up in the exhaust, just a guess, as i'm out of suggestions to check. Thanks for the reply
 
Just for the heck of it get a spark tester, hook it up and crank it over and see what kind of spark you have rather than using the static spark test.
 
Battery voltage of 14.73 on a non running engine might be a question.
However check the high pressure pump in the vapor chamber.
When putting key 'ON' it should run for a few seconds to build pressure.
 
Thanks for everybody's suggestions, Checked all fuses (OK) checked spark at each plug (Good), installed new set of plugs gapped to .030"(still no start), yes when first turn key on fuel pump builds pressure then shuts off, No alarms or lights during start sequence, Defintely backfiring through exhaust after 5 or more seconds of cranking, tilted trim up while cranking engine so I could see prop and seen bright blue flame shoot at least a foot from prop when backfire occurs, high voltage on report is due to charger installed on battery when I saved file. Thanks again for the assistance but I am at a loss, talked to the dealer and will be making the 3 hour drive after work tomorrow to drop off for them to repair, still think it must be the CP sensor malfunctioning or the EMM itself as it sure acts like the timing is off or not consistant.
 
Completely down power the ECM. Remove battery cables, disconnect ECM - wait 1 minute -reconnect.
Sometimes a fouled pug may set off an induction in the CP sensor cable giving a complete funny signal.
However your soft 27 code might indicate an over voltage signal to the ECM at some time that may have damaged it. Never use a charger on a FICHT when the battery cables are connected to the engine.

Not sure of what you mean by disconnecting ECM, as I cannot access all wiring plugs at the bottom of the EMM which I believe are the main power wires. I can although access the plug that hold the red and red/white wire and the other red wire goes to the main engine fuse panel that I also can access, just cant get at the 2 black wires. As far as the soft 27 code, that was recorded on the report at 177 hrs and the high temp code was at 327 hrs which was my fault, during last fall winterizing I did not have enough water pressure on the muffs and at idle recieved that alarm. I will disconnect battery and the wires that I can access for a few hrs and give that a try.
 
Disconnected all power from Battery and EMM, let sit for 20 minutes and rehooked up, cranked engine for 10 seconds, timing lite checks OK, recrancked engine after a 2 second delay and emmediately back fired through exhaust, taking boat to dealer with evoinrude tech to repair. Will post on what they find and cure the problem, just hope its not the EMM, Thanks for all the tips and assistance.
 
Just thought I would post a reply on what the dealer found with my engine, and I knew I should have checked this out before taking it to them as I thought of it on the drive to the dealer
The flywheel turned on the taper, so the CP sensor was telling the EMM the wrong crankshaft position. Resulting out of ignition & injection timing.

Just not sure how the flywheel came loose from the taper, I've owned the engine for the past 2.5 years and never had a wrench on the flywheel nut.
 
Never thought of this on a Ficht but it's always the little things that get you. Thanks for the come back as it's very good info. Seems when you hear Ficht you don't think about basics.
 
Holy Cow, all that time and money because of a Sheard key.
Next time you'll know eh?

Back fires, loping engine idle, sudden pwrup or pwrdn, lots of things can shear those keys.
