OMC Ficht guru wanted

[vrunner79]

I´m having troubles trying to revive a 1998 150 Ficht Evinrude
no experience with those...
engine fires like timing is offset, it does not start
pickup pump is fine, spark plugs new, replaced flywheel cover, (some other broke it)
spark is good...
owner told me he replaced 3 injectors
no more info about
Any help welcome

if you dont have the software, you can check if all the injectors are firing with a timing light. hook up the red to the hot on the solenoid and the black to the ground etc, then take the sensor and attach it around the blue wire i believe. fire off the engine and then check each injector like that. it may be im wrong, because im thinking about the blue wire on an etec.


if there is a blue wire than thats it and you can check it, because it gets the impuls from the EMM

i think stoker (the pubahh on evilrudes) said to watch out on those fichts till, i think, late 1999 when brp took over. stear clear if 700-800 hours on motor. the ecu is a lot of money on these things and can tend to be the root of many problems.

Thanks both, I´m configuring data cable and PC for the EMM reading, but I´m replacing first the crank (flywheel) sensor this evening (Plug & Pray)
spark is erratic, some times big bang, other, small PUFFS..then nothing again
Wish me luck

YEP..I´m hooking the timing lamp also...

Can You communicate with the ECU?

If you can, what RPM is it spinning over at while cranking? It MUST spin at minimum 200rpm. ****If you see RPM the CPS is good!****

Your system voltage key on should be slightly less than battery voltage, when you spin the engine over they system voltage must increase (generally around 14-15 volts)

If it still tries to light & quits still verify:
1. battery voltage on purple/white to left hand connector to the ignition module
2. system voltage (slightly less than battery voltage) key on to white/green to left hand connector to the ignition module
3. ensure ground in present black wire to left hand connector to ignition module
**if all that is good**
1. hook up spark checker & using a back probe, individually probe all the orange w/different color tracers & touch the opposite end to ground quickly. A single spark event should occur, if not the ignition module is bad.
**if spark doesn't occur most likely the ECU is the issue, but I have seen many times the ECU & ignition module both bad**

Good Luck!
