NEED HELP ASAP! - calling all VR6 gurus

[john at subzerodogs.org (John K. Gates)]

Allyn,

I have a '97 Jetta with a VR6.  It will definitely run in a limp mode 
with no MAF, I have seen mine do it with the MAF unplugged.  Likely it 
is the crank position sensor?  There isn't much besides that that would 
cause no spark.  When those coil packs fail (I have seen it way too many 
times on my car for my taste) usually just one fails so you run on four 
cylinders, or four strong and two misfiring.  Your check engine light 
will come on if there is no crank position sensor signal after something 
like 5 seconds of cranking.  See if you can read the code and verify 
that's the problem.  It's not too bad to change if I recall.  Like the 
other guys said of course make sure that big twist lock connector and 
all other affected connectors are tight.  The ECU manages spark from the 
crank position sensor during starting, none of the mixture, etc sensors 
affect it.

Sorry if this is too late to help!
