Gas Coming from motor into exhaust....93 Loyale..

[DC493]

1993 Subaru Loyale D/R Swap EA82 

 

Hey guys after doing my D/R swap I finally got a carrier mount bearing welded up. After a couple of days I went to start it and after a couple of seconds on cranking it I smelled gas BAD so I looked under and noticed gas was puking out of my motor exhaust manifold into the exhaust. Also only on the driver side. I just want to get this car running so I can make sure the swap is working so I can move to EJ. 

Im guessing a cylinder is dead? I checked plugs and they seem fine. anyone have this happen or want to educate me on whats happening? and the proper steps to correcting? 

 

Thanks!

Never had that. 1st thing I think of is some how flooding the intake at the throttle body. Maybe no spark? What had to be disconnected to do the swap?

Injector bad or fuel pressure too high is my guess.

Thats what I was thinking however its happened twice on two separate occasions. I took out the motor and trans and dropped them in car separately. I thought I may have adjusted the throttle cable to high but realized quick that no fuel would get sent in with out the fuel pump being active, right?

, how would I test the injector/ Pressure for EA82s?

 

Thank you!

T a pressure gauge into the fuel supply line, after the filter under the hood.

 

If the fuel pump isn't running, there would be no pressure, or only a little stored.

 

There is no path for fuel to get into the engine / out the exhaust other than through the throttle body.
