Hey Everyone, I'm in need of some trouble shooting, Engine is a 2009 Etec 300 Ser. no. is 05262250 and model no. is E300dpxisr with 160 hrs on it. Took the boat out two weeks ago ran mint, went offshore everything was great, brought it home did my normal rinse out and parked it. I filled the boat up and went to take her out this morning, go to fire up the motor, she just cranks and cranks and cranks,(yes I had the kill switch engaged, I know that its functioning because I get no spark with it disengaged) starter is making contact and turning the flywheel and batteries are charged plenty of juice. So I don't think it is an electrically issue. I changed fuel water separator on boat and fuel filter on motor I also put new plugs in and indexed them correctly. Fuel pump engages took a line off I have plenty of fuel being pumped. I tried playing with the binnacle to see it got bumped out of N.. I have fuel to lines, but I took new plugs out and they seem dry no smell of fuel.. I think that I'm not getting fuel to the cylinders does it sound like I'm correct...I need some help! Maybe I'm missing something I have a feeling its something stupid. I'm currently looking at the engine and standing by the laptop, and I will Respond Quickly. I appreciate any info! Thank you!
MIKE

Did you do what Oly suggested to this other gentleman? As well as the many other things like cranking RPM, voltage drop test, system volts check (SAC), VST return filter, exhaust back pressure fitting, the basics, clean injectors, fuel pressure test and more?  I am also guessing you have the same 09 300HP, because if not your engine could be different test procedures.

Thank you for the response. I’ve done all of the above except the EBP, not sure about that one or how to test it. I’m a new guy here and this is the first post I’ve made. Engines are not the same as above. I’m running 2013 250’s but the symptoms were dead on and I was hoping it was a stupid easy fix and something I just missed. New plugs (gap and index),new filters including return screen checked, good voltage (no drop), good gas, have spark according to tester. Purchased fuel pressure gauge yesterday but was a blow out rain day and couldn’t check but I believe it will test good. Did fuel flow check and was good (removed return and turned key with plenty of flow). Emm has power and lights, no active codes but I have older software. It’s just a crank no start and it came about like I ran out of gas while underway. Just quit on me and wouldn’t re-start. Other motor is fine and got me home. I just paid them off too! Damn. First real issue, +-950 hours. Had injector issues on the other motor and had two replaced but the symptoms are so different. Cant imagine all 6 injectors would die at the same exact moment. There were no prior symptoms whatsoever. It was running perfect right up to the moment it 100% didn’t.

With the extra info like running out of gas while underway, then you just need to make sure fuel is upto the engine and the fuel system is full in the outboard.

I just got done testing pressure and im 99% it’s the pump that went bad. Tested the working motor and it was 40 during cycle and then the non starting one was 20. Shot a squirt of starting fluid into one cylinder and it did what I expected, it stuttered for a split second. Has to be a fuel issue. I’ll do some research on here but is it recommended to do the whole VST assembly or just the pump? No leaks anywhere I can tell. I greatly appreciate the responses! Btw, I didn’t run out of fuel, it was like I did though. Just stopped and wouldn’t start. Guess that’s the last second the pump worked.

It is not alot more to buy the complete VST vs the HP fuel pump only. If the HP pump stopped working you basically did run out of fuel as far as the engine is concerned.

I stand corrected. My boat didn’t run out of gas but my motor did, most of it anyway. Thank you, I will hopefully be a stranger but nice to see people helping each other out on here.
