Suzuki Tale of Woe

Also I pulled the IAC and watched it work with my own eyes, as recommended in the manual.
Thanks

Nope, I'm still thinking ECM for a lot of reasons,(read story from beginning on Suzuki Forum) but if I must, I will haul it out and fix. This is a new problem, the boat came in running but a little rough and ran barely at the dock for troubleshooting, now will not start, it's like electronic deterioration to me, I could put some dry ice on the ECM and see if it works then?
I always like to troubleshoot instead of hanging parts, but that's all the best mechanic I could find would do so far.
Thanks for everyone's help, I'll stay on it till it's fixed.

Yes, I drain it every year at haulout/maintenance, have never seen any even slight contamination. I'm a freak for clean gas, I've been at this a while. A few weeks ago I ran it on a separate 6 gallon tank(it was still sort of running then)
It's quittin' time here on the East Coast, but I was thinking tomorrow, I would drain the VST, and blow out the system w/ compressed air from the low pressure pump to the injector bar and inspect all the gas in a glass jar, I just wish all those weird patterns on my SMIS would go away and I would be sure it's mechanical.
Thanks

"It runs fine on starting fluid" pretty much eliminates a computer/ECM problem & you don't need the SIMS gage to run the engine. Take the vapor separator off, clean & inspect, (your pres. reg. is in the bottom of the float bowl on the vapor separator). If the Float bowl area is all clean & no white/brown crud. Replace the H/P pump, re assemble & install. Go Boating.
:wink: If full of white/brown crud replace assy. :wink: Go Boating

The H/P filter is on top of the vapor separator, #1, change it also. :wink:

Thanks, looks like the next thing to do, the High Pressure filter needs replaced in 300 hundred hours anyhow.

Roger sorry to hear your problems ,Hopefully changing out the VST filters so you can get better pressure and a smooth running engine
Good Luck with the DUCK.
BTW WAWa sells non ethanol fuel 89 octane for under $3.00

I had fuel pressure problems on my 2016 merc had to be towed in 2 times .I was getting similar problems the moter would run and then stop and would not start back up .The problem was it would start and run for a few minutes and then leave you high and dry without fuel pressure on fuel rail I thought it was filters did that and still problems So we changed out fuel pickups on the fueltanks also changed all the water sep filters and gave it a tune up Runs like a top now . Also put all new gas in (non ethanol )with startron .

Thanks, I sure got some bad luck, and my Suzuki dealer is not any help-500.00 for a misdiagnosis.
I'm still working on it, got some pics I'm trying to post.
Thanks
Roger
 
WAWA is now at $3.50 a gallon for 89 octane non ethanol Wow 50cents uptick in a few days

Roger i hope you get the Suzi going Let me know how it goes Jim
