Hello there! I'm Eurocar ! I will try to assist you as much as I can.
first I need to know is the intake clogged with carbon
you may have to remove the hose at the intake and look in there with a flashlight
I have done that. there is a fair amount of gunk in there, but it certainly is not blocked. I stuck a screwdriver in there and scraped some of it out
When the engine does finally catch and start it runs great like there is nothing wrong.
I hope that some of the carbon did not jamb the valve and then bend the valve
what valve are you talking about
how old is the timing belt
timing belt is about 10K miles. I took cover off and verified the pump had not jumped timing. The timing pin fit perfectly and TDC on the crank
ok but after that did you check the start of injection with a scan tool?
no. I don't have a scan tool
also did you use the cam lock and pop the cam gear loose when you did the timing belt?
I bet the start of injection is off
need vag com to see what is the certain values at operating temp to see if it is in range
OK, where can I get a hold of one or is that a VW shop special tool
google ross tech
If it says timing is wrong, what do I do?
what should the correct values be?
first double check the crank at 0 and lock injector pump and cam to verify this
then start the car and let run to operating temp
then with vag com you need to go to 01 engine electronics , 04 basic settings and the 000
you will get 10 values readings
or use the set timing feature button
What are your thoughts as to start timing control?
Can I check voltages to the 3 wires to the pump
that green line is optimal timing and the gray area is within limits
do not tamper the 3 wires
where is this fuel temp sensor
that will not help you at all scan tool is the only way to tune timing correctly after the lock down and verify static timing
in the injector pump
you get that value with the scan tool
2nd value is the advance value (vertical)and 9th value is the fuel temp (horizontal) the green line is the middle of the road
I wish it was easier but this is the only way !!!
ok looks like I need a scan tool
