200 EFI hasnt run in ten years

[Oldcraneguy]

I just acquired a 88 Ranger with a 98 200EFI that hasnt run in 10 yrs I moved the flywheel a cpl inches with my thumb so I know its not froze Im just curious what I should do before trying to fire it? Id like to pull the injectors and try to clean them up and flush the fuel lines and rails and Im wondering if I get the injectors/rails off and turn on the key will the supply pump run? if so will it run long enough to clear the lines/filters or will it shut off after a cpl seconds like a car? also is there any reason to worry about 10 yr old oil in the tank? (its full) any suggestions appreciated....OCG

Re: 200 EFI hasnt run in ten years

I'd pull the injectors and send them out to get cleaned. I can think of 1/2 dozen places that clean them for $12-$25 a piece. Brucato often gets the nod as the "best" place to have them cleaned and adjusted but the bill can get a LOT higher than you expect it to be. PM me for some more reasonable options. The pump will shut off after 30 seconds but its not like a car where the fuel gets flushed back to the tank. It just goes to the VST tank and sits there and recirculates into the fuel lines. I'd pop the top off the VST and clean it out with carb cleaner. Then put it back together and pump fresh gas ( after you dump any gas in the gas tank and refill with fresh gas ) and let it recirc for a little while. Then shut it off and drain the VST. Maybe even change the soft lines. Run premix for your first tank full before you get too happy about the oil injection.

Pull the plugs and give the cylinders a squirt of strong pre mix and turn the motor over by hand a few times. Lets it sit a few days before you try to start it. 10 years is a long time. Dump the old oil.

I can almost guarantee the high pressure fuel pump will be locked up. They can't sit more than a year or so sitting in old fuel without seizing up.

Re: 200 EFI hasnt run in ten years

Thanks for your imput Wired, assuming that the oil injection doesnt work is this a 50-1 or 40-1 engine? also in 98 were these engines designed to tolerate ethanol? and you suggest dumping the oil in the supply tank , does it go bad? or were you thinking condensation?

Re: 200 EFI hasnt run in ten years

Ken, is the high pressure pump mounted in the tank, under the cowl or remote? (I dont pick up the boat till fri)

 

[wired247]

Re: 200 EFI hasnt run in ten years

The high pressure pump is inside the VST which is located under the cowl. Premix on that motor is 50:1. I would never trust 10 year old oil especially out of the container. It oxidizes and gets water. You WILL have to change the water pump impeller . I would change the lower unit oil too.

Thanks s for the advice, I'll let you guys know how things work out...OCG

Re: 200 EFI hasnt run in ten years

UPDATE...Ok I got the boat a week ago and it turns out it has an 95 200XRi with EFI, I pulled the plugs and soaked the cyls. with a mixture of marvel and kroil and let it sit for a day and turned the crank 180 and soaked it again. the next pm I spun it on the starter while squirting motor oil in the throttle body with a pump up sprayer {im a little worried bout rust on the bearings) it spun freely and the oil it shot out showed no signs of rust so I ran comp. and got 117-121 psi. The hi-pressure pump was indeed froze so I replaced that and flushed the lines and vst, and after checking spark I hooked up a gallon of gas with a pint of oil. It fired up quickly but ran crappy as I expected being so oil rich. After about a minute I shut it down and figured it would be a good time to put the new water pump in.
The next day I hooked up str8 gas to it and with water on I fired it again, this time I ran it about 5 minutes till the smoke got down to a reasonable level and it never did hit on all 6 more than a brief moment here and there. So Ive pulled the injectors and will send them out monday....wish me luck and I'll update as things go....ocg

Re: 200 EFI hasnt run in ten years

Can anyone tell me the proper way to check the oil injection system to make sure its working right? I was planning on filling the small tank on the motor and leaving the remote reservoir empty and watching for oil use while running on 50-1 but I wouldnt know how much to expect it to use. Any insight would be appreciated...OCG

Re: 200 EFI hasnt run in ten years

Ok, Ive got it back together save for a cpl hoses that I have to replace but I still have no idea how to determine if the oil system is working, I know I can buy a $15 kit to bypass it but would rather leave it stock if its working right...Anyone help? what would happen if I just didnt fill the oil tanks and ran 50-1 ? alarms? sirens? damage the system? or motor itself?

Re: 200 EFI hasnt run in ten years

The oil injection works with a set of gears . If you run it out of oil the level alarm will sound. If you disable that and run the system dry the oil pump will fail at some point due to no lubrication. Its a very robust system that will alarm you if there is a problem due to the shaft not turning. If the shaft turns it is pumping oil.

Re: 200 EFI hasnt run in ten years

New Problem...when I start the engine fuel starts shooting out of a small hole in the throttle body right beside one of the small hoses that come from the VST... does the same thing when I squeeze the primer bulb...lemme guess...gotta take it back apart? puts out alotta gas

Re: 200 EFI hasnt run in ten years

You might have a blown O ring where the lines go into the throttle body. I had one just yesterday. Could also be a stuck float in the VST.

 

[Oldcraneguy]

Re: 200 EFI hasnt run in ten years

Stuck float it was...Also the correct polarity on the high-pressure pump wires seems to help alot...lol Now if I can just get it to pump water I'll home free, When I put the new impeller in I noticed that the fit around the vertical pipe that goes into the nylon discharge sleeve in the top of the pump was pretty sloppy, and the same with the new pump. It seems odd to me that they put a seal in the pump housing that the sleeve pushes into nicely and nothing for the top that easily has .050" slop? I havent run it more that a cpl mins at a time so far but the heads get hot enough that you dont want to leave your hand on them for more than 5 secs or so and theres no water from the peehole or the exhaust/discharge hole halfway up the midsection...any thoughts....OCG

Regarding the oiling system.

I would remove the tank and empty all of the oil. Clean and flush the tank and many of the components in the system that you can get at. Closely inspect all plastic parts for cracks and replace all hoses.

Air (vacuum) leaks are the main cause of problems in all oil injection system. Any engine over 10 years old should have the smae procedure done. If there is no noticable water in the oil, I would mix it 50/50 with fresh oil and use.

Re: 200 EFI hasnt run in ten years

Ok, running and pumping now, starts easy idles great and throttle response seems perfect for a cpl of minutes then if I pick up rpms to about 2000 or so its fine for a few seconds then starts dropping cyls. and bogging down and will eventually die. I walk back around to the helm and it starts right up again and idles fine. Ive got fuel pressure at the schrader valve on top of the fuel pump/filter even as it dies out. I can see fuel pulsing in the almost full inline filter coming from the tank yet it acts like its starving for fuel, any ideas?...OCG

 

[wired247]

Re: 200 EFI hasnt run in ten years

At this point I think I'd send the ECU in for an evaluation just for peace of mind. Did you get the injectors cleaned? Fuel filter? Could be the TPS, Could be the internal MAP sensor, Could be high speed stator coil, Temp sensor unlikely, power packs, ad infinitum. What is the ID # on the ECU if the tag is still on it? You may want to try starting it up on the muffs with a timing light attached to one cylinder at a time and revving it up to 2000-2500 ish with the fast idle lever and seeing if you have spark dropping off as well.


You say it had been laid up for 10 years. Why?

Re: 200 EFI hasnt run in ten years

Health issues forced the fella I got it from to quit using it for quite awhile, He always intended start again but never did. As far as the fuel system goes, I had the injectors serviced and when I got them back they had all new seals,o-rings and screens. I put a new filter/separator in with new sensor, new hi-pressure pump, cleaned the rail out good but reused the o-rings on the tubes going into it as I didnt have the right ones, they looked ok and I oiled them up before reinstalling them. I flushed the vst and all lines but havnt replaced any of them yet. Im pretty sure that the fuel system is ok cause I get what appears to be hi-pressure out of the schrader just before the fuel rail even as it starts dying out. Is there perhaps a diagnostic port where I can get scanned for error codes like a car?...OCG

Re: 200 EFI hasnt run in ten years

I would pick up a pump gauge. I'd also send the ECU out to Brucato or Simon to have checked on a test rig. First check the spark.

Those are very simple/crude fuel injection systems and there is almost nothing for feedback into the system or reporting functions compared to what you'd find in a modern car or even a modern fuel injected outboard.
