can someone help me with a problem?

[rs2nr]

98 gsx, my windows will not roll down nor will the sunroof and my afc will not turn on also while the key is on the "on" position. The car will not start but the engine will turn. Everything is fine like the, fuel, sparks,fuse, now I don't know what it could be. I was told it could be the ecu, but I am not sure does anyone have any suggestions and if it is the ecu how would I be able to know it is for sure. Iwas told the afc connects to the ecu so if the afc does not work the ecu must be wrong. Is this information accurate?
Thanks.

So you have fuel. You have spark. All your fuses are okay? Including the ones under the hood (not sure on 2g)? If your AFC doesn't turn on then you are not getting power through that circuit. Try powering your AFC (only power 12v wire) through another source and see if it turns on then. If it does then your ECU may not be getting power (not sure which controls ECU power but I think there might be a fuse or a seperate circuit). Did you install anything lately? Check all of the ground connections?

After that if none of that helps take out the ECU and leaving everything connected make sure you are getting 12v (13.8 est while running) from the input circuit to the ECU.

Your problem might just be a bad wire somewhere so check those above then let us know how it turns out and we will try something else (if it doesn't work of course ).

3 weeks ago I had a pioneer in dash installed and when they gave me the car back the check engine light was on and when i turned my turn signals on the check engine light would also blink, could this have caused this, and also how do i check the ground connections?
thanks.

Take it back to the shop but I would do it myself, check all the wiring they have done, they must have tapped some wrong wore or left some open. Your ecu should be getting power because you have spark.

Funny how things all kind of fall together isn't it That could defiantly have something to do with it. Do you have a haynes manual? That should tell you ground locations also Vfaq.com might also. I would gladly look it up for you but I no longer have access to Alldata from my home. There is a chance that they might have left a ground connection open when they installed the pioneer deck. If you have a Autozone where you live see if you can get your hands on their code reader and let me know what codes you have on your engine control unit. You should be able to recall lost information in the prom. Check Vfaq though because there might be more information on it otherwise you might even be able to check codes without a scanner (diag. port trick but not sure if it works on DSMs).

Checking the ground connections involves nothing more then wiggling them to see if they are loose and checking for corrosion.

Im not really familiar with electronics so how would I go about checking the wiring they did? So everything is fine with the ecu? even though the afc does not work. I would love to take my car back to the shop, but is there any way I can get the car started maybe jumping it will that work? Appreciate the help I posted this twice and nobody had any responces, so thanks, appreciate it.

 

[rs2nr]

I disconnected the head unit and still the car would not start. I checked the wiring and it seemed fined they connected the ground to a metal part so i figured that was fine, but still the engine would turn and no start. afc still does not turn on and neither will the windows roll down. Is there still a possibility it can be the head unit?
Thanks.

 

[oldman]

Just making sure you have done the spark test and not just guessing you have spark.

 

[rs2nr]

i do have spark, but i know that that should not be the problem right since my afc and windows will not work, right?

I own and operate a CAR AUDIO store, I would certainly take the vehicle back to them... BUT FIRST take it to another shop you trust - have them DOUBLE check the INSTALLERS work. DO NOT TAKE IT TO THE ORIGINAL SHOP FIRST!!!!

If you have a digital camera email me pictures of his wiring work - I can certainly tell you if any wires are crossed.

It is common for rookie installers to hook up the DIMMER/Illumination wires wrong, this can cause numerous problems in a vehicle (dash cluster failure - no blinkers - no head lights - and so on).

If the installer messed up then you can have the audio store pay for all your damages and repairs. Every shop has insurance to cover mistakes just like this. EXPLORE THIS OPTION

However, in all my time in the car audio arena, I have never seen a car that would not start because of a CD Player install.

IMPORTANT: if your installer touched 12v+ to the casing of your ECU it may be damaged. A 20amp surge to the ECU could be very harmful. if the ECU is under the radio like in 1gs.

GUYS MAKE SURE YOUR INSTALLERS ARE CERTIFIED AND WARRANTY THE PRODUCT AND THE WORK - before you buy!!

 

[rs2nr]

is there anyway to tell if the installer toucheed the casing of the ecu by looking at it? is there anything that I shoul look for? as soon as I take it apart I will get some pictures and put them up. If it is not this does anyone have any idea what would cause this, all the fuses are fine and I really dont wanty the car towed to a shop and I have had no car for 2 weeks now, and those who know how it feels to not have a car, not a good feeling. Thanks for all the help so far appreciate it.

 

[rs2nr]

when i had the installers install the head unit which was about a month ago, wouldn't the car have shut off when they completed the install, why would the car shut off till now, or is it something that happens overtime if they installed it incorrectly? I also only drove the car about 2 times since I had the head unit installed, if that means anything. I just figured that maybe if they had installed it incorrectly wouldn't the problem have happened when they started the car, or is something that will happen overtime?

 

[whitetiger]

there is really no way to tell how long the car could operate with crossed curcuits, it depends on which where crossed and how much current they draw, and how much they were used.

having drivin the car only 2 times since the install, I'm thinkin those guys may have goofed up.

on the other hand, I can tell you 100% it's their fault. did you have you AFC installed or did you do it? you may have bad connections now.

Aftermarket wiring in any vehicle is more pron to mess up than the factory wiring. I say this because guys used butt-end connectors, wire nuts, or electrical tape to install or correct wiring problems. These methods of wiring are not proper and I would guess 30-40% of these types on connections fail to hold up in a high vibration environment.

Tell us EXACTLY what happen during the last time you had the car running.

and I have to ask: why did you not go right back into the AUDIO STORE when you noticed the check engine light and other stuff?

 

[rs2nr]

I called them and asked them what was going on why was my check engine light on and why it was blinking when i turned my turn signal on? all they said was that there was fuses missing and that could have been it and that they placed no hands on the engine. Not knowing that much about this i said ok, but I then comoe to fimd out that fuses have nothing to do with this and now my car wont start. What should I tell them? to come and inspect the car because it's not driveable unless there is someway i can get it started.

 

[rs2nr]

the afc was installed when i purchased the car.

 

[rs2nr]

the car was running fine that's why I did not expect anything. 2 weeks ago i started the car in the morning and everything was fine, then in the faternoon i go to turn the car on and nothing.

 

[oldman]

I know you're frustrated about this but have you ever consider you might just have a bad safc. http://www.ecanfix.com/~aclifford/tree/images/index/mods/superafc/afc.jpg Since the car isn't going anywhere, maybe you should try uninstall the safc following the diagram above. What size injectors are you running? 98 gsx is all we know, maybe more detail will help.

 

[rs2nr]

550 injectors, garret t3 t4, walbro 255, greddy froun mount, afc, apex tt, greddy profec b boost controller, greddy boc, magnacore wires, t3t4 manifold, wastegate,some more but cant think of right now. The afc would cause my car not to start if it does not work, but then why wont my windows roll down and some of the dash lights not work.

 

[oldman]

I'm not saying it is, just trying to give you some ideas. Sometimes when you run out of ideas, process of elimination is the only thing left to do. Did you check all the fuses including the fuse box under the dash?

 

[rs2nr]

yeah i checked every fuse, and nothing there all fine, its just hard trying to figure out whats wrong im starting to get the idea that it might just be the fault of the guys who installed the in dash.

 

[oldman]

Keep in mind you might have to bite the bullet on this one and have it tow to a dsm shop and pay them to fix it. Instead of paying for tow, use that money and buy yourself AAA. Good luck.

 

[rs2nr]

what type of shop would i have to take it to?

 

[oldman]

Call some local shops and talk to them about your problem and get a feeling of how comfortable they are in dealing with electrical problem. You've already learn a lot the last couple of days posting here, I'm sure you will make good judgement.

 

[rs2nr]

yeah i will, but thanks alot for all the help appreciate thanks.
