No i think your doing it all wrong now on a older car like this the inj pump pulley has a 8mm hole in it and this has to be lined up with coresponding hole in the back platei dont think this old a vehicle is common rail but its timed mechanicaly not electronicly ,it may have a wire from the 3rd injector though so make sure the injector is in the right place in the head .iam not where it should be if it has one?? but i think it has ,if fuel to the injectors then it obvious its not timed right ,havent done a V6 engine before to be honest so iam not sure if they have two belts i know the ford escort diesel has two belts anyway i suspect timing is out somewhere along the line ,although the belt showed one tooth out it could have been adjusted by the three bolts on the gearwheel .Now if this does have two belts line it up to TDC1 then spill time it to be sure you are correct ,You sure someone hasnt played with it where the belts went and valves hit pistons so they put a new belt on or the old one back and put it into auction by any chance??

Yes, try the cam shaft position sensor. Also the crank shaft position sensor. It is on the engine where it meets the transmision. Check the wiring.

Audi a4 v6 changed timing belt now can't start no power

The timing must be off. There is a crank lock that must be installed when changing the belt and also a holding "jig" that holds the cams in place while you are changing the belts. Also the cam pulleys must be separated and free from the cam shafts when installing the belt and tensioning in order for the engine to be timed correctly.

2002 start-up problem

Hi there again

Sorry to hear you are still having problems.If you are going to change the pump I would certainly not recommend you do it yourself.If it is the V4 motor I am thinking of, you would need to get to it by removing the rear seat ,remove access panel , and pretty much play around in the gas for an hour or so to get it off in the first place.

What I did find was this on the net on a recall by Audi to replace 2002/03 model fuel pumps as noted below.

RE: 2002 Audi A4 Fuel Pump Change:

I just had my fuel pump changed out by the dealer. Here is what the letter said-

"Safety Recall JL 2003 year Audi A4 quattro with 1.8L Turbo or 3.0L engine and 2003 Model year Audi A6 with 3.0L engine"
The fuel pump on some affected vehicles may contain a carbon brush set that is susceptible to premature wear.

On invoice it says-

JL12 Install fuel delivery unit and sealing washer.
1 8E0-919-133-G Washer
1 8E0-906-087-P Fuel Pump

No charge for unit or install. Just call them up and give the vin number to see if your car is affected. On the other note of your code error '1&3 misfire',try and have it re-set (it might be an old error)and see if it comes back. Hope this helps ,and I will research your problem further with pleasure if need more help.

1995 AUDI 90 CS - Hard to start... spark & fuel OK

Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.

I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.

My mechanic told me it is probably a starter.

This starting issue sounds like either the ignition timing is way off, or the cam timing is, the whinning sounds like the timing chain may have been replaced with a non silent type chain (plastic cam gear teeth), maybe the onwer got this wrong when he installed it and the cam timing is off.
