88 5Ktq hall sender issues (frustration mounting)

[jesper moreau]

Restating the obvious - it is good you have a code.  You should be 
concentrating on the ignition - don't go off on a tangent, as some other 
replies suggested other non-related things to look at. Don't assume that you 
have everything correct with distributor adjustment and wiring - double 
check.

2113 (Blink Fault Code), VAG1551/2 Fault Code Number 00515
Hall sender in distributor
Distributor alignment, faulty sender,
Mis-located sensor & distributor

Most likely you simply have the distributor not adjusted with respect to the 
flywheel sensors.  In short, the Hall signal needs to be synchronized with 
the RPM sender and Reference sender signals that are from the sensors 
located on the bellhousing.  If any of these signals is not present or out 
of sequence, no primary signal will be sent from the ECU.

Make sure you did not inadvertantly mix up any of these sensor wires.  They 
are easy to mixup as the color of the cables and wires inside are all the 
same for each.  Sometimes the color band comes off and they get plugged into 
the wrong sensor.  Double check these by doing continuity loop from the ECU 
harness out 1) to the RPM and Ref sender, you should see about 1K ohm for 
both RPM and REF sender.  If they are mixed up, however a  different code 
would be thrown, or as in my case, no code at all.  It is easy to mix one of 
these up with the knock sensor- that is what happened to me.  Continuity 
check to each of the connectors for the various sensors may be in order.  I 
simply used a paper clip or small wire to loop back the yellow and black 
wires then test for continuity at the appropriate wires at the ECU harness.

With no primary, the fuel pump relay will not trigger either, so don't 
suspect it faulty if not hearing the fuel pump.

Make sure the coil pack with transistor signal amplifier is grounded well, 
and make sure you have continuity between the ECU and this module.

I had a no-spark condition recently resolved.  On mine I had no code, but 
following the above methodically, I found the problem.  If you find yourself 
getting bogged down, you may need to step away from the problem for awhile 
then come back to it and retrace your steps - take notes of what you are 
doing in the process.

for additional information regaring the ECU pinout, etc.

Let us know what you find.
