Ok fixed one problem now I have two huge problems. Hey everyone.
Well I have 2 big problems now.
1. When I go WOT my gauges (factory + aftermarket) in the car die. The 10amp fuse blows completely. When I rev the car in WOT without being in gear it does not do this. What could this be. We thought it might be the gauges but we disconnected them and it did not change anything. I had this happened to me before with my aftermarket tach. I took everything off and the problem went away.
2. After my first fuse blew, I started getting SES lights. I used autotap to decode them and this is what I got:
P0171 Fuel trim system Lean Bank 1.
P0174 Fuel trim system Lean Bank 2.
What are these caused by? Is my tuning not correct? I hear the pump running and I have 42lb injectors so I do not understand why I would be going lean.
I also have zero knock and never drop below .92 mv on the O2 sensors. Infact I dont think it ever goes below whole numbers.
I have noticed that when the car is idleing it has a lope in it. It drops to 200 when I rev it high and let off.

Re: Ok fixed one problem now I have two huge problems. There is a ground strap that should run from the drivers side engine block, behind the fuel pump, to the frame rail just under the ABS module. The frame ground has the engine strap and another sensor ground.
Make sure these are installed and TIGHT.
Grounding is critical in these cars.

Re: Ok fixed one problem now I have two huge problems. My aftermarket pump is grounded in the back of the car. It is grounded to the clip that holds the fuel lines. Is this incorrect? I would assume that you are talking about the stock pump?
I dont think that the ground upfront is loose or incorrect. The car would not start then and we never touched it durring the install. Infact I am wondering if the wire that comes off the PCS to the white tach wire is sending volts back causing the fuse to blow. I remember when I hooked up my 5" monster tach this was happening. When I took the tach wire off and removed the _+ leads the problem stopped. I have grounded my after market guages on the screw just below the glove box (install university). I would not see why my pump ground could be the problem since it runs. If the ground was no good the circuit would not be complete and the thing would not run.

Re: Ok fixed one problem now I have two huge problems. Try putting a 1 amp Diode between the tach and PCS. (black with silver stripe) Pick one up at Radio Shack and put silver stripe towards PCS, make sure to insulate the diode frome grounding out.

Re: Ok fixed one problem now I have two huge problems. Ok well here are the results.
1st I wired in the diode and took the car out. There was no SES light when I started the car even though there was one the night before. I took the car out poped the clutch and wham the gauges went out again. I autotaped it and this was the error I was given: P0650 Malfunction Indicator Lamp (MIL) control circuit. P1626 Theft Deterrant Fuel enable signal not recieved.
2nd I then got the car back home replaced the fuse and removed the hot lead for the gauges. I then took the car out again. I went WOT and the fuse did not blow. So now I know that my gauges are the problem.
However when I got the car back home almost instantly I got a SES light. I now have the following codes: P0171 Fuel trim system Lean Bank 1. P0174 Fuel trim system Lean Bank 2. Does anyone know what could be causing this?
Also I have another problem. While my boost guauge was not working before (it never showed any boost) I do not think the blower is making any boost. The car feels stock when driving it around. It does not pull like it has a supercharger on it and I sense no increase in acceleration. I noticed when looking at the blower that the pully moves and makes a rattling noise. Should I tighten this bolt? Also ATI shipped my kit with a 4.00 pulley shouldnt it be a 3.6 to make 8psi at 5900rpms?

Hang in there, buddy.
I know it is a PITA to be dealing with stupid issues when you are on the verge of getting your speed-demon set. But, take your time and check everything.
When you do this the first time out, there is a lot you don't know, and it's easy to miss something. Always assume what you think it is may not be, and check for something else, too.

Re: Ok fixed one problem now I have two huge problems. I'm gonna make this offer one more time, then I'm gonna shut up:
While you can get to your car and I can get to mine, call me, and we can double-check your install of the kit, at least, visually, part by part.
If you are interested, email me and I will send you my number. If you can't afford the call, I am willing to call you. <img border="0" alt="[angel]" title="" src="graemlins/gr_angel.gif" />
No way is the tune so far off that it produces the problems you see. Remember, the same source helped me with my tune and my result speaks for itself. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Ok fixed one problem now I have two huge problems. BlackLS1TA thanks for the help.
When I was referring to the pulley I was referring to the one on the head unit of the blower, not the harmonic balancer pulley. Is that what you are talking about?
That would be great to talk over the phone, however I am back at school in Norfolk and wont be able to see the car. I would have to wait until Friday or Sat when I am home from school in Alexandria. I am pretty damn sure I got everything installed. I mean the blower wines like crazy it just does not seem to have any power. I even checked for belt dust thinking it might be slipping but that was not the case. I have no idea why I am not seeing boost (other than the nylon tubing has been kinked). I know my gauge is not correct, but the car does not pull either, so something has to be wrong. Is the 4.0 pulley correct to make 8psi? Do you have any idea what might be wrong with me running lean on banks 1 and 2?

Re: Ok fixed one problem now I have two huge problems. Since I have the same blower pulley, I'll say you have the wrong one too. I emailed ati about it, and they said it sounded like I should have the 3.7 or 3.6" pulley (duh, that's what the other people got). They said to call them and they'd figure it out. But I think you might want to get these other gauge/pcm problems worked out first. Which sound fricken wierd btw <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> . Where are you gettign power for the gauges from? And they all ground under the glove box somewhere?
BTW my sig says 8#, but it's only doin 5#.

Re: Ok fixed one problem now I have two huge problems. AzzHauler - I am getting the power from the ignition circuit just below the guages fuse. I simply ran a wire with a clip into the single fuse, which is probably why the guages are blowing. What I am going to do is wire them in before the fuse and I think that should do the trick.
I would like to get the correct pulley so I will call ATI and find out. Do you think I need to tighten the pulley to keep it from making the ratteling noise? Do you possibly think that is one of the reasons I am not seeing boost?

Re: Ok fixed one problem now I have two huge problems. There is a rattly-chirpy noise to the step-up gears in the SC. The SC pulley is pressed on; the bolt only holds that in place. It wouldn't be rattling on the bolt, for instance. The pulley wouldn't be spinning on the shaft of the SC.
You have some other problem why you are not seeing boost.

Re: Ok fixed one problem now I have two huge problems. Oh ok thats cool I just wanted to make sure that was normal. So based on your response its actually the other pulley that gets replaced when you increase boost? Do you think I am running lean because my pump does not switch on to high mode until 5,000-5,500 rpms?
Thanks again for the help.

Re: Ok fixed one problem now I have two huge problems. Yoy can get a smaller SC pulley or a larger crank pulley to increase boost. Right now, there are various SC pulleys to choose from.
However, the crank pulley appears to be preferable because smaller pulley sizes increases slippage.
If you have NO boost, something is set up wrong. You do not have some minor tuning problem. Something is wrong with your kit setup.

Re: Ok fixed one problem now I have two huge problems. Blackls1ta - Thanks for the info.
I talked to Kenny, he said the ses light is a minor tuning issue and would not hurt the car.
He said he would call ATI and have them send out a different pulley to increase the boost. He also said he would retune my computer after I did some logging with autotap.
I think the reason I am not seeing any boost is b/c there is a kink in the nlyon tubeing. What can I replace this with? I am pretty sure the blower is making some boost, I just dont think its much. I really cant say until I strip my pod down and rerun some new tubeing for the boost gauge.
This summer I plan to upgrade my pulley system to an 8 rib but for now I would just like to get the damn thing working right. I am going to take some pictures of the setup and post them on the board. Thanks for your help again. I will know more when I get back home this weekend and tear things apart.

so you still have the stock pump? how much boost r u running? maybe the pump just cant handle the load

Re: Ok fixed one problem now I have two huge problems. Hey everyone here is an update.
1. I fixed the boost gauge. I replaced the nylon tube with copper and that did the trick. (PITA)
2. I am seeing a consistant 4-5psi at 6000 rpms.
3. I still get an SES light that comes on and off when driving for different intervals. I think this is due to the programing and the MAFS. No knock has been detected.
4. Last night while driving around my right blinker light did not work. I then start up the car this morning and it works again. When something goes wrong with the guages, I simply turn off the car and it goes away. I have not had a probem with the indicator light since. Perhaps it was a chance case. Do you think that my 3 gauges are pulling too much power of the guage power line? I hooked mine up before the fues box to a fat pink wire for the 20 amp guages fuse. Electrial problems really suck.
5. I also sometimes appear to get some belt slip. It happens at different times and in different gears but I will be flying and then the car no longer pulls and just seems to be reving.
6. I was thinking that if it is not belt slip could my Stage III star spec clutch not be up to the task of holding the power. It is brand new so it should not be worn out. The only reason I do not think this is the car is that it has never happened in first gear. It seems to occur mostly in 2-3.
Thank you for all your help.
Happy Easter
