Vehicle make/model = 1996 pontiac sunfire
Mileage = 268,000
Engine size = 2.2L
dash lights = No
codes = No
work done prior = Changed 1 of the fuel injectors
work done to repair = none
tech = KK
question = I had a fuel injector leaking around the O ring. I took the
leaky injector out and put in a brand new one with a new o ring. When I
put everything back together the car wouldnt start. There is gasoline
blowing out of the exhaust linkage bt the manifold. I removed all the
spark plugs and the fuel is spewing from the far right cylinder. Right
beside the one that I changed the injector on. None of the other cylinders
are doing this just the far right one. I took everything apart again
and looked at that particular injector and put another one in its place,
put it all back together and still the same thing. Gas spewing out the
cylendar when trying to start the cer. Any ideas on what could cause
this?
KK:
A leaking fuel pressure regulator is a common failure for having the cylinder(s) fill with
gasoline. When they leak, fuel gets pumped into the vacuum line, and then into the
cylinders.
It is also possible that there is some debre in the end of the fuel rail, at cylinder # 4
injector area, and after having the rail off, the debre is floating around and plugging up
that injector. Let me know what you find.
