I pulled my 76 2.0 stock fuel injection engine a few months back so that I could plug up some oil leaks. Other than the leaks, the engine was running O.K. Well, as O.K. as I could tell after a couple of weeks of owning my first 914. I put the engine back in just a couple weekends ago and have slowly been trying to get her going again. For a couple of days I could only get her to spin with the starter, but I wasn't getting any fuel.....I figured out today that I hadn't connected the wiring harness to the distributor. Now that I have it connected I cranked her over and I am now firing on just the #3 cylinder. I also don't smell and raw fuel coming out of the exhaust. And when I open the throttle, she seems to power up a little bit, but not much.
major points 76 2.0L D-Jet rebuilt/cleaned injectors from cruzin performance new large and small injector rubber new vacc. hoses all around just had it tuned up before I needed to pull the engine and I didn't screw with the ignition system at all. I hear no clicking when I move the throttle switch (thought I was supposed to hear the injectors clicking) If there are any other bits of info that will help in the trouble shooting process please let me know.

sounds like a set of known good injectors would be useful for trouble shooting. Cruzin is really good with their service - you probably got back some numbers before and after cleaning - did they indicate there was a significant problem before cleaning? I'm wondering if you have fuel filter problems that is letting crap through that has reclogged your newly cleaned injectors. Perhaps take an injector and hook it up to a couple of D cells - listen for the click. You should be able to easily blow through them with the solenoid open. Don't leave the power applied too long.

Cruzin's report said that one injector was flowing much lower than the other 3. (and I did have one cylinder running leaner than the others) and after their servicing the flow rates were much closer. I will try a couple Ds and see what I hear. If I don't hear anything should I up the voltage to get them unstuck? |
