Not sure what to do next

[avarvelo]

I have a 99 2.0 95,000 miles that has been sitting for almost 3 years. It was running perfect when I last drove it. About a year ago I had to drive it about 2 miles and it just died at a light. I was able to start it and get it going buy keeping the revs up. So, its been sitting since b/c I got it towed back after I got where I was going.

I have already replaced the fuel pump,fuel filter,battery,spark plugs,oil and filter and emptied out as much of the old gas as I could and added probably about 5 gallons of fresh gas. I am pretty sure its the speed sensor or camshaft sensor.

Any suggestions or ideas would be great b/c I dont have a code scanner and since its dead I cant even get it to an auto parts store to use theirs.


Thanks

make sure that you dont have any vacume leaks

[Picknicker]

Maybe it's the air flow meter? Check wheather it's plugged in correctly and has no leaks.
If this was no NB but a old bug I'd say clean your carb^^

[gilligan]

Check the air cleaner box probably a squirrels nest in it or something.

[avarvelo]

Could the settings in my computer been wiped out because it sat so long with a dead battery?

[avarvelo]

No other suggestions? anyone

I have a '98 that has been sitting for about three months and it needs a head gasket; I started it yesterday and it ran fine (as I anticipated) for about 15 minutes. I wanted to circulate the oil one last time before I tear it down this weekend. Then it began to act as you described.

So to make a long story short (I was diagnosing my problem with my Bentley manual)...

1) Check fuse 28 (fuel pump)
2) Check the output stage of the coil (ignition system)
3) Check the Motronic ECM (I have no idea what it is)

I'll keep reading if I come across anything else I'll let you know.

well now that i think of it you may have snapped a timing belt...that could be a reason for a no start/no run.

ECU will be fine just sitting.

you need to make sure your getting fuel, air and spark

pull a plug wire and make sure youg getting spark
you can pull one of the fuel lines to see if it is pumping fuel
and air is hard to check for but the timing belt could be a cause for no air

[avarvelo]

It starts but instantly dies out as soon as I let go of the key. I am getting fuel,air and spark. The timing belt is still there. Im still thinking its the computer,camshaft sensor or speed sensor. This really sucks I need to get this thing running buy june 1 and am about to start throwing more parts at it but money is tight and parts as we all know are expensive

[vdubbugman53]

cam sensor would be a good start then. it wont stay on if you rev it?

[avarvelo]

No it dosent stay on when I try to rev it. When it cranks it sounds exactly like it should. Then it just dies out.

[Lnzbug]

The belt doesn't have to be broken. It could just be missing teeth and actually not moving at all. Not a good sign. That's what mine did and I ended up with bent valves

[avarvelo]

It moves but im going to check it out anyway thanks for the idea

[Basher]

Is it getting fuel? I'm not a great engine mechanic, but if you try to crank it and then remove a spark plug, you should be able to see if there's fuel on the plug right?

[vdubbugman53]

here is how i would narrow things down.

Check Spark- Pull a plug and see if you can see it spark, or hold the plug wire....you pick. Id personally pull the plug

Check for fuel- Pull a fuel line to the Fuel rail and see if she pumps there, all 4 injectors wont go bad all at 1 time

Check for Air- Make sure your timing belt is still intact. Rarely do they jump enough teeth to make the car not run at all.

I think you also have a good idea on the cam position sensor. also look in to the crank position sensor.

[avarvelo]

I have spark fuel and air and my timing belt is fine

Anyone know how to get the cam position sensor out?

[wawalker]

I have a suggestion. If you just start to remove parts and replace them because you have a feeling they could be the problem you will wind up spending a ton of money and still have a broken car. It will probably be cheaper to buy a cheap OBD II code scanner and start there.

[vdubbugman53]

get on the vortex...there has to be somebody in your area with a VAG Com

[avarvelo]

So I bought a scanner. This is what I got...

17951 P1543
Throttle Actuation Potentiometer Signal too Low

17988 P1580
Throttle Actuator B1 Malfunction

17645 P1237
Cyl.1-Fuel Inj.Circ. Open Circ.

17646 P1238
Cyl.2-Fuel Inj.Circ. Open Circ.

17647 P1239
Cyl.3-Fuel Inj.Circ. Open Circ.

17648 P1240
Cyl.4-Fuel Inj.Circ. Open Circ.

16725- P0341
Camshaft Pos.Sensor Circ Range/Performance

Any ideas? Anybody every have similar codes?

[avarvelo]

So I cleared the codes. Removed the manifold cleaned up the TB it was bad but not to bad. But it still didnt start. So I scanned the codes and this is all that I got....

17951 P1543
Throttle Actuation Potentiometer Signal too Low

Is this an internally bad TB(sensor or plastic gears)?
