1999 115hp evinrude ficht

[Landshark93]

We’ll i pressure tested the fuel pump and got 5 psi next step is to test the lift pump it says to apply 15 psi to pulse nipple do I just pop a little air in there with a compressor?

Never mind the compressor it says to apply 15 psi to the same pulse nipple I’ll have my gauge attached to

 

[Crosbyman]

not having the specs on the 1999 5psi seems....very low.

the book on 70hp says minimum 34 psi so the 155hp should certainly have more than 5psi ... to pressurize try a few key on 3-4 and test fuel pressure.




the lift pump can be simulated by hand pumping I doubt it is the issue
in any event if you hand pump and the VST does not fill up there may be a blockage .

have you checked the VST return filter to see if you have one first of all and is it packed with crud enouh to mess up fuel circulation ?

test the HP pump by applying voltage. it should spin and bring up the PSI to norm whatever that is on athe 1999 FICHT



VST is just a can to cool fuel and vent air/fuel fumes

btw found a post where 40 volts was the expected voltage with engine running...? odd
you have EV Diagnostics... any fault codes active ??

Two thumbs up to you Crosbyman!!
Your full of great info.
I love this form and it restores my faith in humanity to see people helping out.
I have very little knowledge of the ficht and E TEC technology and this is always an interesting read for me.
Thanks for all you do to help others.
Best

I enjoy this hobby and just try to help out best I can while I learn as much as I can, not having spent my life in a outboard shop other than my shed !

Had a few crow pies but it is part of learning. I hope landshark gets his 115hp FICHT going. I am trying to get a copy of the 115hp book. The one I have access to only covers up to 70hp FICHT.

Not bringing up any fault codes
The filter is full and no curd or nothing in there and the pump is no going up any more then 5 psi going to remove it see if it’s clogged or any obvious issues and I won’t be able to get a good reading on the voltage or codes until I get this running I’m guessing not entirely sure

if anything like ETECs you have filter you can see on the side but....
have you checked the VST return line filter per picture above.... and below .

Dirty filter photo reference

Just thought I would share what your fuel filters should NOT look like .. regular and vst. 📷 📷

this is the one your referring to right?

there was no filter present on the pump i have removed the pump the service manual is telling me to replace pump after checking the lift pump & circulation pump Along with a voltage test

 

[Crosbyman]

filter #7 is a VST return line filter .... nothing to do with the HP pump base screen filter

if your version of the HP pump does not have an inlet filter at the bottom and the pump seems blocked or won't spin enough by applying 12v & grd directly to it then run some light oil in it to try and free it up.

VST/HP pump assemblies are getting hard to find but can be replaced with other models Walbro I believe. the Pump alone can be replaced but web search is needed.

if you do check the vst return for presence of a conical filter vst barbs are very delicate !!

here are links to ficht up to 70 ...for some base info you can download and print

and ....next is a link to 2002 and up ETEC FICHT for added info

I have pretty much covered what may be the issues to clear up.

Yes thankyou everything has been very helpful e took the pump off cleaned it out little oil in and i was wondering why there was no fuel in it so I have a problem with my lift pump I hooked my fuel directly to the pump and it went to about 23 psi and I broke the top nipple off also lol will be fixing that so now for another day il take off the front fuel assembly and see if there is a clog when I bought the motor it was on a skid laying flat so maybe something got clogged while it had been sitting because it supposedly ran from the paper work I got from the mechanic shops this older gentleman had it at hoping that this motor is worth my time in effort I’m about 800$ in it so far with the motor price and other parts I have bought

Anyone one know what this is was kind of tucked behind the fuel filter

Nvm think I found it air temp sensor

 

[Crosbyman]

no offense but you need to progress in steps to ensure proper fuel flow
to get your PSI up to specs

btw unable to open your atachement ... temp sensor must be ok no EMM faults


tank pick-up not clogged ?
tank hose is good to engine lift pump ?
lift pump surface filter screen ok ?
Lift pump needs crankcase pulses to run like old style pumps..pulse hose OK?
lift pump's inside diaphragm not punctured or ripped ?
lift pump to VST hose ok?
fuel filter ok ?
VST float not stuck shut ? see video venting ok ?
VST fuel to HS pump channel open
etc...

ok been reading on ETEC KEY ON voltage.... 12v olt is fine at all inj and coils etc....
40 volts running should be it from what I can gig up.

 

[KXP]

Bought a deck boat with a 98 ficht 150 horse and when I did reviews I took it to the boat shop and had them put an old 80s 150 horse Johnson I am glad I did I don’t have the ability like you to fix it so good job on fixing it.

 

[Crosbyman]

Been reading a lot abouthe FICHT nightmares but..... the 115 was apparently the better one of the lot.
The bigger engines ( 150 +) seem to have been very problemeatic yet comments on the 115 have been mostly from happy campers.

it depends.... as they say. a lot of problems come from poor upkeep.

 

[Landshark93]

update on the ficht rebuilt the lift pump got everything back together it’s working now fuel pump sitting at 20 psi which the manual says 20-30 is good engine fires up. ev diag is saying #4 fuel injector is stuck open and it’s still getting hot the video in the forum for replacing the injectors on this engine I’ve done the steps he did in the video and it doesn’t work idk if that’s because the fuel injectors I bought don’t have the QR code ? Not entirely sure . Any help is appreciated thanks guys .

 

[Crosbyman]

getting hot may be fuel flow cooling issue inside the inj or return hose ?? is the 2nd one getting hot also ???


the EMM likley means.... the injector circuit is open .. this does men that the injector's internal drive coil is OPEN . I doubt 2 inj.coils would be internally open anyway

That said, the EMM only knows "OPEN" because it does not see the 40v injector voltage returning on the control wire used to trigger the injector with ground pulses.


If such is the case start by actually measuring the injector's internal loop resistance (few ohms) ... measure across the connector injector side ! Compare results with a working injector

if the injector wiring is faulty a new injector will always show OPEN on EV Diag.

check that the faulty inj. is getting it's 40 volts from the main buss feed

inspect very closely.... the return control wire to the EMM. poke prod twist it while looking at the EV diagnostic in case it clears up. That 40v loops around inside the inj.coil and exits on the control wire going to the EMM logic.

Turn the key OFF disconnect the EMM inj. connector inspect and apply electrical contact cleaner . While the connector is out measure the specific control wire for continuity back to the injecto's connector. (EMM side)

if ok reconnect all connectors on the EMM


DO NOT RUN NEW INJECTORS WITHOUT UPDATING THE INJ. PROFILE IN THE EMM.
seems you can run at idle speeds for testing only.

typical injector to EMM J2 connector on 2002+ 115 HP FICHT PIN #1 GREEN

white-black is 40V supply
