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.
