EA71 dies on right turns

[Ryanb]

I'm trying to help a buddy get his car running strong. After six months of sitting , we did a full tune and the thing purs. It runs abaout as strong as 1.8 with the swampers. Only problem is, every time we make a hard right, the little ea71 shuts off.

 

I have never experienced this before. I tried to search around, but had little luck. Anybody ever dealt with this? Any insight for me?

 

Thanks,

check to make sure the coil wire isnt grounding out somewhere.

Float level is off - is it running a Weber? My brand new Redline weber ($400!) would die on hard left turns. Float level was off from the factory in Mexico.

 

Anyway, even the Hitachi can have the same problem. If the level of fuel in the float chamber isn't kept correct at all times, the fuel pressure pressure can drop or spike and cause the engine to die.

Thanks for the info...I'll look into both of these things.

 

GD. will the float level issue be obvious to the eye if I take the float bowl apart and check it out? It's a hitachi I think, but it also may be one of those crappy carter's..haven't looked that closely yet.

 

In any event, lets hope I can get is fixed.

Does the thing just flat out stall? Or does it sputter and die? If it kills the motor, then I would suspect an electrical issue. If it were fuel, the motor would probably sputter alittle before dying.

I had a Datsun 810 2dr (rare find) that would do the same thing. It turned out to be a bad relay that controls the fuel pump. On right turns, the coil inside the relay casing would move, if just slightly, and the result was loss of electrical connections. Don't know for sure, but would assume the Subie has a relay controling the fuel pump.

Yea, no sputtering. It just straight turns off. I have nopt had the car back to look at it yet, but I'm suspecting electrical..we will see. I need to get a longer look when I have more day light.

If the float is off, it won't sputter much at all - the idle circuit is very sensitive, and if you round a sharp corner with the clutch engaged the engine will drop and try to idle - but not have any fuel. It will pretty much just die out. That's what mine would do on hard left turns. If I kept the clutch out it wasn't real noticeable as the wheels drive the engine at a higher speed, and the float level is not as important off-idle.

 

Try taking the corner with the clutch engaged but with your foot reving the engine slightly - use the hand brake if you need to slow down. That will tell you if it's dying because of fuel starvation of the idle circuit, or something completely un-fuel related.
