Well I tried firing it up. The starter is good and the engine turns and kinda bobbles. Like it's not getting fuel and/or spark. I'm going back into the garage to poke around...
I'm just glad it tried to start! Haha! Yay!
-edit- I pulled the spark plugs and they didn't smell like fuel and I don't hear the fuel pump click from the cabin or anything. I thought I used to hear it prime when I had my FS. Justin, what was the wiring for the fuel pump again?

Woooo! Baby steps!
Well I think I'm getting fuel since the spark plugs smell like it but alas, no spark. I'm going to check my wiring to the disty tomorrow. We were using the 1996 wiring diagram so perhaps something is a little off. Arg, I'm soooo close.
I did get the air intake system all mapped out. I picked up a K&N cone filter on eBay for $38 shipped then ran to Autozone and Summit for the piping and couplers. I was so embarrassed to be standing in the ricer aisle picking out the tubing though. heh-heh. But it's plastic so it won't get heat soaked and I spray painted the tubing black with plastic spray paint. A day of drying and the tubes don't chip so that's good. I also drilled out holes and put grommits in for the vacuum line and air intake temp sesnor. Pics tomorrow.
And I had about 1/2" of slack in my throttle cable to deal with. I tried some plastic spacers but couldn't get them to work. My gf had a good idea about using a spring so I could just coil it around the throttle cable between the pedal and plastic clip, but couldn't find any the right length but I found some of these littel guys and they were like $2 for the assortment pack. I just had to open one up just a bit to slip over the throttle cable then sinched it back down once it was on there. Works pretty well. So the throttle cable is sorted.

stop copying me. i had the idea to have no spark first =P lol. i hope you figure out whats wrong.
And the hardline for the power steering pump I got from a 626 was leaking badly. So I went to O'Reily's to try to find some hose. I got a hose reducer so I just need 6" of hose. The guy there ordered it for me and said it would be in by today at 3pm. So I stop by to pick it up and he ordered 2' of 3/8" hose. I was hot and crabby from working in the garage and pissed this is taking forever so I just tossed it back on the counter and said "Really? God damn it..." I told him I'll just go to Summit Racing for hose from now on. THen I heard the ole "Well what car is it for?". The part and part number don't exsist, it's for an engine swap. "Well, what year is the car, maybe I can look it up?". FML. So I didn't get s*** done today.
Pablo and I checked the wiring and even when the wire we hooked up through the fuse block for the injectors and disty had direct power from the battery we still didn't get fuel or spark. It's like my fuel pump isn't working. I grouned the FP relay wire to the P5 ECU, that didn't work. I jumped it to the KL ECU, that didn't work. Pablo did some quick looking around about MegaSquirt and I'm about done with this wiring and about to drop $650 on their system.
I'm in a bad mood tonight. Maybe tomorrow will be better. I just want my slow car back. heh-heh

is the fuel pump not coming on or is it that the injectors are not firing? or both? and which pin did you ground

Megasquirt! (humpleg)
Lol those monkeys... I went into Autozone the other day because we lost a clip off my buddy's Yakima bike rack. It looks just like one of the clips that holds the brake line fitting onto the strut. We took another one in to show the guy and he's like "just tell me what the application is" and I'm like "it's not going to be in the system, I can tell you that now. What size clips do you have?" And he's like "well what car is it for?" I tell him it's for a bike rack and he's like "A bike ra.. ohhh.." and looks hopelessly lost. Ugh, morons, they can't think outside the fricken box!

Don't despair, you'll get it running but now you need to be patient!
I really know nothing about how you're wiring this up... From what I recall, your wiring harness and ECU match and you're sure you have the right ECU pinout, right?
If I were in your shoes I'd check the signals from all the essential sensors at the ECU to make sure it's getting something. If there's no spark and the injectors aren't running it sounds like the ECU is missing some important signal. Does this motor have cam/crank sensors? I'd start with that, if you have a multimeter that has a frequency counter mode, use that to check if the ECU is getting pulses from those sensors (also, check that the sensors are getting power).
I know this isn't the fun part for you but it'll be very rewarding when you figure it out (and you'll learn some cool s*** along the way).

Well Justin said "for the fuel pump ground the fuel pump relay wire at the protege ecu." so i grounded the P5 fuel pump (pin 80, violet wire) and it still didn't do anything. But Pablo and I didn't see why we would need to mess with the FP with the P5 but we jumped the FP relay wire to the KL harness FP relay and still nothing.
I wasn't even positive which fuel line from the P5 was feed and return so both fuel lines are open at the firewall now. We tried cranking it and still nothing. And we wired the disty and injectors right from the battery and still nothing. Pablo has more info since I just kinda does what he says with wiring.
Megasquirt would be nice, but just as much of a headache and crazy expensive. $650 is a lot of cash. And I'll have to pull the P5 and Milly harness and strip them and wire them up to the MS system. Then tune it myself with my laptop. Yikes. That's all kind of the last resort right now.
I'll post what we have wired and stuff tomorrow and maybe you guys can help me out.

I wouldn't try to tune MS myself. I'd probably look for a base tune on PT and then take it to like B3R to get it fine tuned. I'm sure it would develop a lot more power, and also be safer, too.
You said you got a new disty, right? I've heard they can be problematic on the KL's. I think it's the ignitor specifically, but don't quote me, I'm only toes deep in my research...

there's a couple of wires from the disty that go to the main relay (according to the diagrams), those are the ones we had connected to the battery (with a fuse) but still no spark. I don't know why the fuel pump isn't working, we didn't hear it whine when the switch is set to ON and no fuel comes from the lines while cranking. I thought the pump would still be controlled by the P5 ECU so we left it as it was, nothing. Evan had grounded the signal but still nothing, then we jumped it to the KL and still nothing. I don't know if it needs to be removed from the P5 ECU over to the KL...
The thing about the MS I don't like is that there is no feedback from a knock sensor, and it's a system I could actually make myself... I've had those micro-controllers fail on me with systems that are not as critical as this so I wouldn't trust it too much, not to say it doesn't work, but like I told Evan I'd rather spend a grand on a low end Haltech... not an easy decision

is this how you are grounding the FP relay? Once you do this we did nothing else to get it working. Having it like this, when the key is in the "ON" position the fuel pump runs constantly. It no longer primes for just a second its always on with the key at "ON" not Acc or Off.
If its like this. I would test the relay for the fuel pump and the fuse box, Also, not positive there is one, but if there is a fuse for it, check that.

I don't know if that's how he grounded it, but I checked the fuse and it's fine. Evan?
ok, if you ground it on the harness connector side then its not going to do anything. This was the simplest part of wiring we did, and it allowed me to figure out which fuel line was feel since I forgot to mark them during the pulling of the 1.8l
I think that's how I wired it, but I'll double check when I get home. Thanks a lot Pablo and Justin. Justin, those diagrams you draw are SO much easier for me to understand than wiring diagrams. heh-heh, thanks man.
