Did you check to see if the timing belt broke? Did it die while driving or not restart after shut off?

Ask Your Own VW Question
Customer reply replied 2 years ago
The timing belt is fine there is no 12 volts to injector pump which should occur when turning on the key this is a safety valve which is also the one I run a 12 volt reference signal to and still no fuel pressure to injectors as I cracked the fuel line 2 injectors. I'm assuming that there's no power to the secondary which is controlled by the computer I have no reference to check voltage to that. To narrow the problem down I need to be able to check for voltages to computer or other device that could shut down power.
Customer reply replied 2 years ago
It did die while driving after taking of from a stop. It has new timing belt 5k miles ago.
Customer reply replied 2 years ago

Does the check engine light come on when you turn the key on (self check)? If so, then the ECM is powered and online. Do you have any way of reading faults?

Codess
P0121
P0605
P1161
P1256
P1403
P1I62
I have a bad throttle sensor but this is not cause me any problems yet. I cleared all the codes code p1562 keeps returning after clearing code one key is turned on without engine even being cranked over. So I tested the 8 pin connector to injection pump pin 1 & 2 2 & 3 metered 5.6 ohms pin 6 & 7 1 ohm. After resetting computer safety valve now has 12 volts will not start no pressure to injectors. Computer thinks there's a problem with pump I think there's a wiring issue what to check next.
VW Mechanic: gomi_otaku, VW Technician replied 2 years ago

The fault that most concerns me is the P0605- this is basically saying that the ECM is faulty. I think a circuit has gone bad, that is why you have the issue plus all the various faults for temp, pressure, EGR, etc.

I have a new ecm I have a ready tried that.
The thermistat is stuck I have new part for that as well but nether issue is causing problem with starting.
So let's back up a second I have cleared all the codes then code 1562 pops up after turning key on without starting motor whereas I have voltage to main shut off and PIN number 5 when the code appears voltage to pump turns off. Best I can tell without a service manual I either have a bad pump or a wire. The best I can tell from the code is it thanks something is out of range in the limiting circuit. I have already changed parts because I have the parts and it was easy to try can you get schematics so we can figure it out.
Customer reply replied 2 years ago
Egr is plugged I have Egr delete kit to fix this problem. Pressure problem from hole in tubing inside ecm I have already replaced.
VW Mechanic: gomi_otaku, VW Technician replied 2 years ago

So you have 12v at pin 5 at the pump?

the fault is for the quantity adjuster on the pump- measure the resistance of it, you should have beween .5-2.5 ohms.

Make sure the wiring to this is OK-

It sounds to me like you may have lost your pump.

Customer reply replied 2 years ago
1+2 2+3. 5.6 ohm
6+7 ohm .9 is this the quantity adjuster pin out. I checked my other vw and the pump ohms the same within .2 ohms I am having a hard time believing the pump is bad need to check wiring, what are the pinout to check wiring harness.

I have 12v at pin 5

Sorry- that one just shows the start of injection timing connection. Getting the other one

VW Mechanic: gomi_otaku, VW Technician replied 2 years ago

Actually that diagram has both the fuel shutoff and the start of injection timing. So you just need to check to make sure you have power to the glow plug module, and the wiring to the shutoff is OK- if not, it may be that your start of injection timing sensor is faulty.
