The air pump has definitely been removed and there is a pulley in its place. I'll have to take a look whenever I pick up the car and see what exactly it is. Speaking of which, it's almost done! Precision said it's running pretty well, but they're having trouble getting the turbo control system to work. Apparently the lines were "simplified" by another shop out of NC, Rotorsports Racing. They have a pretty good rep and I think they know what they're doing...I think Precision is just not understanding what was done, and I wasn't able to find out much from Rotorsports. They said that they bypassed a lot of the factory hard lines since they had been tampered with. Completely bypassed the FPR solenoid too. I think the thieves may have tampered with the turbo controls as well, believe it or not...Precision said they hooked up the lines just like they were when the car came to them. And it ran great when I had it. But, the FPR was not bypassed, according to them. So, sort of a guessing game at this point as to how it was hooked up. Do you know much about the turbo control routing? Hopefully, Precision will get it figured out and it'll be done by the end of the week. (I can't even count how many times I've said that now...)

As for the idle thing, I'm guessing that is not an issue anymore as they've been driving it around. Might have been something in the old wiring harness. I'll check the TPS and ISC anyway.

If there is a pulley in it's place, then you have some sort of deletion kit already. If you only have the crank, water pump, alternator, power steering and/or A/C pulleys, than there is no pulley in place of the air pump. Get my drift? No pun intended haha.

Maybe Precision should call Rotorsports. The guys at Rotorsports are very knowledgable from what I understand. I've talked to Brian over there and he's a good guy. They're constantly tuning people's cars too, building engines and all that. It's definitely not a fly-by-night organization. I think you can bypass the FPR solenoid without much consequence. I did it on my single turbo vacuum line setup. My line goes straight from the LIM to the FPR, and I took that solenoid out and now I don't have any solendoids under there whatsoever, and my rats nest (metal portion of it) is completely gone. If I could look at it, it would really help. I won't be able to do that until June though, unless you can limp it to CS in a couple weeks. I MIGHT be able to make it to Denver when I get back but not sure yet. I have a bunch of different vacuum diagrams, and they're on rx7club too. If you talk to Rotorsports again, ask them if they used a simplified sequential diagram, and if they can send you a copy or you can send them a copy that you have. Basically to just see if you can get something in your hands to use as a reference to fix it.

Let me know what happens. If I can, I'll give you a hand and see if we can get it running right after I get back.

Yeah, I tried to get Precision to call Rotorsports, but they weren't too keen on that idea for some reason. Whatever. I did email Rotorsports again yesterday asking if they had a diagram they used for the simplified lines, or any other info that might help out. I haven't heard back yet, but this is what they said in the original email:

"Regarding the vacuum lines- we did correct a lot of the vacuum hose routing on this car in order to get the turbo controls to boost properly, the vacuum routing was done to simplify the operations since the factory "rat's nest" of metal lines had already been tampered with (by the previous owner) and we do usually eliminate the factory fuel pressure regulator solenoid for reliability reasons and to maintain proper fuel pressure."

I'm sure I can limp the car wherever. Precision said it runs pretty well, just doesn't boost right. However, they seem kind of determined to fix the problem on their own, haha. I'm not sure if I should just tell them that I'll fix it myself...they're not charging any extra for it. But if they can't figure it out before you get back I'll take matters into my own hands.

get all chuck norris on them...then it will be fixed.

chuck norris was in a car accident, lost both his legs and still walked it off!

Sounds like Precision is being difficult haha. I still have my rat's nest, it has most of the solenoids and vacuum lines still on it. We could just use it and set it up completely stock if nothing else works.

I have the dealership's vacuum hose diagram. That is like a transparent 3-4 page setup if you guys need that its all color coded and it could be a huge help if you are going to be mapping shit out. Lemme know if you want to borrow it or whatever.

speedjunkie · Postby **speedjunkie** » Thu Apr 30, 2009 9:14

Well it'll be a couple weeks before I'm back to even get into my storage unit to get the rat's nest. I'll let you know then though, unless he does something with it before I get back. Thanks!

Are you gonna be at any Sonic meets in Denver this summer? I'm planning on hitting that again sometime soon.

Ranger · Postby **Ranger** » Mon May 04, 2009 9:14

Yeah! I will definitely start going to sonic meets again once my car is done. I'm still a little worried about it being stolen again though...need to get some serious protection on it. Not to mention there are still wires hanging down from the dash...I don't know how but the thieves were obviously able to easily start it with just that. I think I'm just going to have to remove the ECU wherever I go :rolleyes:

Anyway, spoke with Precision again today. They said they think the vacuum lines were fine, and that it's probably the wiring harness that's messed up. They think it was causing an injector to misfire, or something...which makes no sense to me, as they said it was running well the last time I talked to them :confused:

Supposedly they have a working wiring harness they are going to swap in this week...more waiting for me...

speedjunkie · Postby **speedjunkie** » Mon May 04, 2009 9:14

Yeah I hear you on the theft thing. Although my car wasn't stolen, I'm being told my stereo was stolen when it was sitting outside the shop the other night, apparently unlocked for SOME reason. I'm wondering why they didn't steal all the gauges in there too. Something smells fishy. Removing the ECU would definitely help HAHA.

Hmmm, that sounds like it could be possible. However, I wouldn't mess around with an issue with fuel. You'll end up blowing your engine, or at least 1 rotor, if you run to lean on it, especially under boost. Are they trying to say the thieves were messing with the engine wiring harness trying to start the car? Like under the hood or down by the ECU? Because I can't see why the wires under the dash would have anything to do with a fuel issue. Of course, I'd still be skeptical of that anyway because if it's working fine sometimes and not other times, that doesn't sound like a fuel issue due to wiring. You never know though, gremlins mob deep in these cars.

Ranger · Postby **Ranger** » Tue May 05, 2009 9:14

Well, I don't quite get it either. I don't think there is a fuel issue. Certainly Precision is smart enough to know that if the car runs lean the engine is going to blow. And they'd be responsible for that...so I don't think that's the case. What I was saying is that they are still trying to figure out why the turbos aren't boosting, and they think it's something in the wiring harness. That's what my last post was in reference to. But on the phone they said "maybe" an injector wasn't firing properly, or something along those lines. I didn't think to question this at the time even though it doesn't make sense. Maybe they don't know what's wrong so they're trying everything they can think of :rolleyes:

As for the whole thing about the thieves messing with the wiring...that was a statement unrelated to what Precision is doing. I was saying that there are wires hanging under my dash that were not there before it was stolen...

Sorry for how blurry that last one is. I'm sure they used this to hotwire the car somehow. The ignition wasn't punched and there's no way they had a key. I'm pretty sure there's supposed to be a cover over those wires though...so maybe they're supposed to be there, and they're just hanging down, with the cover gone?

speedjunkie · Postby **speedjunkie** » Wed May 06, 2009 9:14

Well if they're right and a fuel injector isn't firing right, that's still a problem that must be fixed, but like you said, I'd hope they're smart enough to know that. I don't knock them for not knowing and trying everything though, if that's the case, because sometimes these things are wily haha. Like I said, gremlins are abundant in these cars sometimes. I still haven't broken my old engine apart to figure out what went wrong, but it didn't seem like it should have blown.

From what I can remember, there is no panel that goes there, those wires are just kinda stuffed up there. But actually, I'm not sure those are stock wires, I can't remember but they don't look stock. Do you/did you have an alarm? Do you have gauges? Have you traced those wires to see where they go?

you have it back right?

I was thinking the same thing...they don't look stock. It only had the factory alarm, so I'd say it's not that. But I do have a couple aftermarket gauges...a/f meter and a boost gauge. I also have a Power FC so those wires could have been added when that was installed. I haven't had a chance to trace them...I'll put it on my list of things to do to this car whenever I get it back :rolleyes:

deepSpeedMS3 wrote:you have it back right?

Well, the car was found a few weeks after it was stolen. Unfortunately the motor was blown. It's been in a shop for over half a year now. So, technically I have it back, if that's what you meant...but I don't have it back in my garage...
