Got a 2000 225 EFI Merc…Motor wont run on its own…I pulled front off and put short bolts in to hold injectors frame in…Injectors are squirtting but I dont know if that is enough…They arent fogging??..Sprayed some mixed gas in and the motor runs fine…Pulled fuel pump assem out and took apart and cleaned…alot of nasty stuff inside…Dont know how all that gunk could get by water separ, fuel filter and straner on bottom of fuel pump…but did…took injectors and fuel rail apart and cleaned but still wont run…HELP…Can Injectors be cleaned…or do you just replace…What is voltage for injector silnoid…if 12 can you put 12 volts on them to open and spray them out…Just searching for anything now…8 hours on this project today and I am stumped…Thanks in advance for any possible fixes…Have three of these motors on the boat and this one is the only one not wanting to play
gunk probably didnt get “past” filters it “grows”
yes, injectors can be cleaned
several places you can send them to have them flow tested and cleaned
about $25-35 each
first things first
compression test
spark check
fuel pressure test
if all those are good, then look at teh injectors
Thanks Chris for reply…Might give you a call monday am…Carl

Carl,
Did you pull the fuel pump in the VST tank?
Usually that pump gets fouled up and can’t supply the pressure for the injectors.
Sometimes cleaning it still doesn’t get everything out.
They are usually about $250-$350 depending on what pump you have…

Sorry for delay…Yeah pulled the pump…it was locked up…forward and rev a couple of times and it cleaned up and ran…been busy this week hadnt had time do any thing with it this week…how much fuel pressure should be there???..The motor will run fine if yoou spray fuel through the fuel rail… so i would think everything else is good but fuel…Right???..The injectors are pumping fuel …I just dont think enough fuel…what is the best way to check fuel pressure??
