[urq] UrQ frustration

[Louis-Alain Richard]

Hi Mike,

I hope it is not the sensor, because it is a PITA to remove from the
transmission bellhousing if the engine is still attached. Maybe other
listers have a way to remove it easily ? I wasn't able to remove one without
destroying it with a hammer...

Steve,

got an 035 PN for UrQ vs an 034 PN for the 5KTQ, can any one confirm or deny
compatibility?

Unless the car will continue to run if the pin falls out (and on this one it
may), I'd say unlikey as it ran, turned off with key and would not start 20
seconds later, nor would it start hours later when cool.

As I mentioned I ran through the IST no start check list.  As the pages were
stuck together I did miss page #1, the set #1 to TDC and check cam gear and
dizzy.  Unlikely it was rotor, coil wire or plug connectors after sitting
for 20 seconds.  Checked F/TCU per IST OK, checked speed ref sensor, OK,
checked reference mark sensor signal NOT OK, checked Hall power OK, checked
coil, OK, checked ICU, OK, and mentioned fuel pump relay not in the system
and no freq valve on this car.

Could be more likely than above, but car is not home so will need to bring
some tools to check.
