With my new engine and turbo and cooling system rebuilt I assumed I was ready to go. Sadly I was unable to even start my car as I had leaking injectors.
After much running around like a headless chicken, I managed to find a place that could test and flow my 'untested' injectors that Chris had.
B & M Fuel Systems
3 Albert St, Richmond
While the injectors checked out, another more disturbing issue had arisen. The injectors in the JA have a special rubber 'seat' that holds them in place. With the car being twenty four years old, they had benn completely eaten away. Mitsubishi can't help and nothing else seems to fit.
In desperation I resorted to 'Anything goes' style tactics and amazingly the final product gets the two thumbs up. My system has been holding strong for many moths now and others have had similar success.
This will allow you to replace all the O-rings in the ECI, including the 'seats'.
What you need:
* 1x 56x2.5N70
* 1x 90x2N70
* 5x 7x2N70 I've said Viton for the injectors, but not needed!
* 4x ????
Here's the injectors and the 'seat' replacement idea

As long as the injectors aren't leaking out of the wiring, you should be ready to go!
I might also add that I was having major starting problems that I could not understand as the injector assembly seemed operational!
I eventually found the culprit! Here's what happened...
I arrived at my car to again find it won't start as usual. I unplug the injectors, but I decided to check that the sensor wires were plugged in (I had already done this in case you were going to be a smart-arse), which they were, but to my utter amazement, the other end of the wires comes loose!? WTF!!!
On closer inspection I find that the main plug on the throttlebody is damaged. Not "Damaged" as such, but the clip that holds both sides together is broken. A quick re-plug and connect it back into the holder and...
Car starts first time, everytime. No more hiccups and my temp gauge is back on line. So the plug must have been ajar just a touch and the fault was intermittent. Not far enough to be visibly apart! Bastard!
If you are having major problems with your injectors leaking and need to get the car to start, unplug the injectors from the clip (follow the wires down from the ECI cap to plug), start the car and then quickly re-insert the plug. WIll at least get you moving until you turn the car off again! This process is much easier with a friend as you don't need to run!
