ok so i just did a headgasket on my 1990 vw jetta 1.6 td. when coldstarting it takes forever to start, i usually have to boost it because the battery does not have the reserve to crank the car over, once the vehicle starts it runs excessivly smokey, and very rough, on only about 2-3 cylinders, now if i pull the cold start lever out the car smooths right out and clears up, but if i push it in it runs like a bag. once the car warms up for a bout 10 to 15 min it seems to run fine. now i ve checke the compression on all 4 cylinders it is fine, about 425-430 psi per cylinder, all 4 glowplugs worked fine in the car before, am in the process of checking them at the moment. i did notice injector number three bubbling slightly at the head where it threads in, but the injector is threaded in all the way and cranked right down. i thought maybe air in the line where the "in" line attached to the pump so i put a hoseclamp on there. i am not to sure what could be doing this, but i am leaning towards air or possibly stuck injectors??. i verified that my pump and cam are all in time. if anyones got any ideas lemme know, im kinda stumped on this one

What setting do you have the pump dialed into?

only thing changed on the pump is the max fuel screw, it has been turned in 1 turn, other than that the pump is stock

I think Vince was asking about your timing proceedure for the pump. As in, when you had the dial indicator in to set the timing, how many mm of advance did you set it to?

Did you use new heatsheilds after compression check? Also did they go in correctly? Don't over tighten the Injector to fix the leak the head will crack. This is all just in case you didn't know...it could save you money.

Yup, I'm wondering how many mm / inchs you've set the timing to?
Extremely retarded timing could contribute heavily to your symptoms.

yes i put new heat shields in the head, umm to be honest it never occured to me to check with the dial indicator, i never had the pump off the car, so i all i did was re-align the timing marks, on the pump to TDC, wtih th advance puched in or off. i guess the dial indicator will be next step. would the bently manual list the timing spec??

Yeah, the timing marks, if they exist, are rough rough rough guides at best just to get the timing belt on the right teeth. Actual injection timing is much more subtle.
The Bentley has the full procedure... here's some additional pictures/info that may be helpful:

Went out today to mess with it, it started right up still only firing one injector, run ok idled a little rough then keep giving it gas to keep it running then it acted like it loaded up and died. then wouldnt start at all. Any ideas? What would cause only one injector to fire and not the other?

lots of air in the other 3 lines...
will your car run out of a can of diesel? like a super clean gallon jug or whatever... just run a line from your filter into the can of diesel, and run the return line in there also.

I'd just advance the timing a little at a time until it runs good without rattling too much.
