Well, some better news on the Spirit. After getting all motovated earlier by fixing the oil leak on the Horizon, and then getting off work a little earlier tonite.. i decided to dig into the spirit and see what the deal was. I was just going to compression check the other 3 cyls to see where they're at, then pull the cam and check for leakdown. I pumped up the other 3 cyls and they were kosher. Just for shits and giggles i did #4 again only to see it pump up to 130.

Um, ok. Whatever the fuck happened before? All I know now is that I have compression. Did someone return my piston??
I put the spark plug back in and fire it up just to see. Same deal, #4 is still dead. Hmm.. I have dad out with me this time so we go back thru the troubleshooting. Check the plug, wire, check for spark. That's all good. Take off the injector plug again and put the noid light in.. we got injector signal. It almost HAS to be a fuel issue. I put a little bit of gas into the spark plug hole and put the plug in and fire it up.. couldnt really hear if it ran on all 4 at first. Pulled the plug out and it was wet. (I forgot to mention that every time i would run the engine and pull the plug, it was black and dry). Put the plug back in, ran some more (maybe 30 secs), took the plug out and it was dry again. Ran it with the plug out and it really wasnt puffing much out of the hole at all. We're pretty much convinced that either the injector is fried or plugged up damn good. This is shitty because I dont have any extra +40s laying around. I get out the ohm meter and measure a good injector.. then the +40 and they measure the same... Ok, i guess the injector is good.
While just brainstorming ideas with turbo dodge guys on AIM, i stumble upon something with potential. My friend just happened to say that if the FP is too low with the +40s, they dont work. And that #4 would stop first because it's farthest from the FPR. I blew that idea out of the water thinking that the pressure had to be right since i took the whole intake/injectors/AFPR/TB off Larry's engine and put it on mine. I made an effort not to touch anything so it would be already set for me to work off of. They all worked fine on Larry's car, so the FP must be right since i didnt touch it... right? Then the light bulb came on... Larry was running a 2.2... I'm running a 2.5! 2.5s suck quite a bit more fuel than 2.2s do. Well, at WOT at least. I'm not sure about at idle.
Thats where my stopping point was for tonite. I was actually relieved that it WASNT the injector since i didnt want to pull the intake to change it, and to buy a new one on top of that. Tomorrow I'll start it up and crank up the fuel pressure to see what happens. That may be all that's wrong!!! If that doesnt do it, i guess I need to clean the injector and try again. Cross your fingers for me that it's just too low of fuel pressure!!!!!
