Diving in

[Creelux]

Hi everyone,  i recently picked up a 1986 gl10 wagon 4wd turbo wagon.  It wasn't running when it s parked in 2009. Ran just before it was. My son snd I are going to bring her back to life.  One thing im nit sure what engine is in it. I can't find an obvious clarification.  This would help me finding parts.  Ive started with the basics.  Plugs, wires coil, distributor,  rotor oil change,  fluids and etc. Fuel system debating? Filter yes, anything else??? Like dropping ther tank and drain?. Anybody have things to consider before i turn the key for fire??

Engine should be an EA82T , you’ll see that in the heads if you get a good look around them. 

Lots to say here. The basics are fine but before you get too deep maybe do a compression test. How’s the oil and coolant ? Not mixture ? Closed air system so be sure all ductwork and breathing hoses are not cracked. 
 

You found the right place for support. I’m not the best that’s for sure but I did own a couple of these at least. Don’t panic if it blows smoke when you do get it started. 
 

Should you need parts they are getting very hard to locate. 
 

Best of luck with the project.

On the front top of the block near the power steering pump (from memory) you’ll find an “EA82” in the casting of the block halve. 

I’d look at dropping the tank and cleaning it out unless you can clean it out/dilute the stale fuel in there to get it running. 

You might need a new efi pump, if you’re lucky it’ll fire up with the current pump. I’d cycle the pump a number of times to flush the fuel lines before cranking it over. The fuel pump primes for several seconds when you first turn the ignition on and when the test connectors are connected together (engine off ignition on). 

Cheers

The oil was dirty/old. Normal looking color. Their was nothing in the radistor. Someone drained it. I appreciate the advice. Should i disconnect a fuel line to cycle the efi pump?  

[moosens]

One thing you could do is take the fuel pump off and reverse polarity and it’ll flush itself out. And then confirm it works. Those are hard to find and if you were to see how much the dealers would get for them you’d give up on the spot. NLA these days I’d have to guess. There are alternatives. 
 

Fuel pump is in the rear of the car underside on a small shelf as I recall. Just fore of the right rear axle.

Do not do this! The efi pump replies on fuel to cool itself - yes, there is fuel flowing through the internals of the pump’s electric motor. All EFI pumps are like this. 

If it’s possible to reverse the polarity and run the pump I wouldn’t do it. Pull a fuel line and blow compressed air back into the tank if you really need to - make sure the fuel cap is removed.

It’s only for like two seconds. Done it plenty of times. Passed to me from elders with decades of experience.

Just sayin.

 

We deal with more rusty tanks up here.

1.8 liter turbo wagon.

85-88 changes are confusing theres a hundred changes on that engine over those years.

theyre sometimes hard to look up at parts stores depending on their listings, I’d guess you’re finding that out?

NGK plugs and wires are best on Subaru’s.

While it is an EA82T, that doesn’t help look up parts.

That old gas won’t do you any favors - tank pump and lines.  Otherwise I’ve had some old ones that sat fire right up. 

[Creelux]

Man, thanks so much.  Everones  advice is sound and logical.  So that im understanding correctly,  remove efi / disconnect hoses snd reverse the +/- . Should cause pumped to run in reverse. Also blow into a fuel line back to the tank with cap off to clear the line. 

 

Any suggestions about dropping the tank?? Is it imperative? Any alternatives. Like siphon the tank add mor fuel snd re siphon???

Try that first if you can siphon the fuel out - or pump it out with a Fawcett pump if going straight from the tank to bucket. Other way to try would be fill with good fuel, throw a new fuel filter in there and use the EFI pump that’s already there to do the work if it’s up to it - collect the fuel from the return line. Use as much clean fuel as you like, I’d initially double what’s in there, flush, once low, throw another jerry can of clean fuel in there, flush another litre or two then try for a fire up. 

Good idea to do fresh spark plugs and a well charged battery with a vehicle also jumping the starter battery (with correct voltage spike protection).

This is '89 TBI tank.  Supposedly fits '87 - '89 wagon.  Can understand why it doesn't interchange back - '85 and '86 were carbed, but why not Loyale?

Thanks Bennie

Its been awhile, ive been working on this car with my son.  We have done many things to it including your suggestions. We fired it up this weekend and it ran. After changing some bad fuel lines shortly after it started it ran for awhile. Smokey and leaky. Things appearead to level out, but it has a heck of a time starting again after it got up to temp.  I did break the the thermo vaccuum valve but capped the 3 little hoses off.. do you have some ideas?

You said earlier you took out the distributor. I would suggest that you need to make absolutely sure the rotor is pointing right at the #1 post on the cap at TDC using the IGNITION timing marks on the flywheel. In other words, if you took the dizzy out without the car running to verify it was in right, it may not be in right after the first shot. Ask me how I know that "it's very close" isn't good enough. Follow the FSM instructions for this when it comes to the positions of the cam pulleys in relation to TDC on the compression stroke.

It will interchange and bolt up no worries. What changes is there is extra internal baffling for the external EFI pump. And the outlet to the pump is larger than the carb variety. 

There may be other small differences for emissions etc, but they’d be minor and easy to work around I reckon.
