clicking injector - #3 on ej22 swap

[johnceggleston]

the engine is in, everything is reconnected except the exhaust. my second cat is busted so i'm waiting on repair or replace before bolting on the y-pipe and front cat. this means no o2 sensors are connected.

 

when i turn the key to 'run' i hear the #3 injector clicking continuously and what sounds like the fuel pump doing the same thing. the injector quits clicking when i unplug it, duh. the sound from the rear actually sounds like it is coming from behind the RR tire but the fuel pump is the only thing i can think of in that general area.

 

and it will not start. i know it has fuel but i haven't started checking for spark, compression or actual fuel in the cylinders. it was late when i tried to start it.

 

any ideas on how to deal with the injector and the fuel pump? clicking?

 

history: 1995 ej22 125k w/egr from a salvage yard. passenger camshaft and sprocket were broken in an accident. i replaced both from a 96 ej22. new nkg plugs and subaru wires. fresh oil and filter new t-belt, sesls, idlers and water pump. it's installed in 98 outback 140k auto .

 

i have the rest of the 96 ej22 for parts, but the injectors are gray instead of red. does that matter??

 

please help!

 

thanks, john

I memory serves grey was for California emissions and red was for everywhere else. You may need to swap all 4 so they have compatible timing delays. You may also be better off swapping the whole fuel rail so you don't break the injectors while extracting them from the fuel rail.

Check the main engine harness connectors and make sure they are moisture free, clean and tight.

 

The fuel pump is trying to keep pressure in the system and the #3 injector is being powered and porting pressure. The injector is most likely good, you have an electrical issue.

 

You can verify this by swapping the injector plug to the back injector, if that one starts acting up it's electrical!

larry,

thanks for the input. i finally got back to the car today, swapped the ECU and it fired right up. it looked looks the carpet has gotten wet and there was some corrosion on the old ecu, but it runs and i'm happy.

 

thanks again,

john
