Moar info

[2000AS4]

I picked it up from some one that said it had low compression in cylinnder 5 but i dont think low compression isnt gonna start the car. I looked throught the timing belts and they seem fine and in good order. Some one said about cam shaft sensors but im not sure. The guy that i got the car from said it was his daily driver. after the low compression he went in to autozone and ever since it wouldnt start. IDK but if anyone know what it could be please let me know.

Thanks.

So you bought a very expensive car to work on that doesn't run and you don't know how to work on cars? You are doing a very poor job of describing the issues with your car. If you want any kind of meaningful help, your are going to have to do a better job describing your issue(s). You also need to VAG your car. Is your check engine light on? From you original description of the motor not wanting to turn over, it sound like a weak/bad battery or starter issue...

[force fed]

Gotta vag it. Could be cam sensor... or battery, tb, wiring, fuel pump, ecu or any and everthing else that could cause a no start, does it have gas in it?

[Peter1.8t]

Huh Bigger wastegates????

[DESPOT D S4]

Huh Bigger wastegates????

exactly my question

[ChescoS6]

From the information provided it seems you may have the same problem I had last
Month. The fuel pump went in mine. Can you hear the fuel pump when you turn the
key prior to start. Also the relay is behind the driver knee bolster.

How do i VAG it im new to Audi?

Or buy a cable from eBay or find someone local that has it. Maybe check the regional forums for that.

Do you have a CEL? Autozone can scan for free.

Did you check the fuel pump, relay and fuse?

[2000AS4]

I was told first to chech my cam sensors and crank, my cam sensors did have some white film forming on the magnet. could that be it??

[2000AS4]

and i cant check the check engine light becasue the car wont start so all lights are on, and i cant drive it to autzone becasue it it wont run, i ordered cam and crank sensors hopefully that will help me out a bit

[zrider91r]

go to autozone and buy a cheap obd2 reader.. run about 30$ up here in cali.
far cheaper than the vag(which i just ordered) and it will give you the codes that you need to get your car running..
also, try putting a charger on your battery.

[CELison]

pull codes and check for fuel and spark. and more info on those big boy wastegates!

[2000AS4]

lol there actually downpipes lol not wastegates
and Thanks for the help guys!!!!!!!!!

[2000AS4]

NO HOMO

[ECS Tuning-Audi]

Scan the codes with a code reader. We have one available below. It could be a number of things, Fuel pump, fuel pump relay, crank position sensor..

I hope this helps!

So i changed my cam sensor and my crank sensor and it still wont run? fuel is pumping and i just changed the sparks, and the coils, no check engine codes are given? im stuck anyone ideas?? thanks

[csosnowski]

what are you scanning the car with that you are getting no codes?

how do you know fuel is pumping?

if the fuel pump relay is bad it can disable the injectors, so even though the fuel pump may be working the ecu will not be able to fire the injectors. are your spark plugs wet with fuel after trying to start?

do you know if you have spark at all?

[Brendon1098]

just stop throwing parts at it now and pay someone to fix it

[2000AS4]

i know the fuel is pumping i unplugged the cable and tried turning the car and fuel was squirting. i rented the 400 dollar new machine from o'riellys and had the fuel injector circuit come up, i realized the injectors were unplugged so i plugged them back in and now there is now codes being read. its a can obd2/obd1 and abs machine.

[csosnowski]

ok so you wont have any vag specific codes unless you have a vagcom or gecko (dealer) machine.

so you have codes now? which ones?

[A62TURBO]

Lower it.

[csosnowski]

Lower it.

lol

[B5S4Life]

I feel like this is bad a joke........lol

[mightemouce]

I feel like this is bad a joke........lol

This..

when you say it doesn't crank all the way over, can you rotate the motor fully by hand?

[zrider91r]

check timing?

[zrider91r]

or caress her gently..

[B5S4Life]

or caress her gently..

Most certainly this. She'll start right up.

[2000AS4]

lol no there are no codes being read. the timing is in place i chacked. the motor revs up just doesnt start. i can explain but it like its starts but it doesnt. as if its something little. And ive caressed her enough and she still dont wanna make me happy lol

[csosnowski]

its hard to believe that theres no codes being thrown.

does it feel like its firing at all? are you able to take video?

[2000AS4]

ya ill post a video when i get home. if anyone has ever had a fuel cut off switch or i guess a bad fuel pump thats what the car sounds like. it wants to start but seems like something is missing.
Also if anyone has a vagcom for sale or lives in portland oregon and wants to help me out that be great, or ill buy one if anyone has one.

[rlny]

could it be a kill switch???? i know i accidently turned it on in my car once and was baffled for a few min why it wouldnt start lol

[mightemouce]

lol no there are no codes being read. the timing is in place i chacked. the motor revs up just doesnt start. i can explain but it like its starts but it doesnt. as if its something little. And ive caressed her enough and she still dont wanna make me happy lol

.....

[2000AS4]

where is the cut off switch located? i didnt install one, is there one that comes from factory?

[Sales@EPL]

Nope, unless the previous owner installed one.

When I ran into a similar issue on my S4, it ended up being the crank position sensor/engine speed sensor. Although I haven't personally seen this, it could also be a bad coolant temp sensor as other members have reported that being the culprit of their no-start issues. I'm not a fan of blindly replacing parts, but the CTS is only a few bucks and a relatively simple DIY. Part number 059 919 501A.

My CTS has gone bad as well, but I never caused my car to not start. However, neither my CTS or my crank position sensor threw codes when they failed.

[schusters4]

What kind of ecu tune does it have? Is it possible that the "kill" program was accidentally selected? It seems as though if there were an issue with the engine turning over...... There would be a code associated with it. GL

[schusters4]

Trailer it to Matrix and be done with this thread.....

[zrider91r]

OH my APR tune had a anti theft mode that left me trailering my car home.. Turned out I had to enter my code and she started up..

Is your check engine light flashing, and the EPS light on?
If it is it will crank forever but never start.. at least mine did anyways..

[CELison]

does the engine sound like its cranking faster than it should? This happened to my buddy. Prev owner faked receipts for the tbelt. snapped trying to turn it over at 140k.
