Gentlemen,
I have an extremely difficult no-start condition on my rally car ('90 Talon tsi) I wanted to throw by you.
I haven't rallied this car since 2006...it's been stored and not running since then.
This spring I patched everything up and tried to start it...here is the problem:
The fuel injectors will not fire during cranking only. They DO fire for a second when the key returns to the run position.
I can 'prime' the engine by hand turning the cam sensor (key in ON position)which fires the injectors. The engine will then start and run fine. It will even start again as long as there is still some fuel remaining in the cylinders.
I have swapped\tested the following with no change in behavior:
ECU
cam sensor
fuel injector resistor
water temp sensor
grounds (ground directly to battery now)
Main power relay
unplugged the TPS
fuel pressure is good
spark during cranking
Bottom line is no fuel injector trigger during cranking only.
Since there is spark I can't believe it's the igniton switch but maybe I am wrong.
Motor is completely stock.
Anyone have any ideas?
Thanks,
-Dave
