Hey guys, I've got a no start situation with my 1z mtdi swap, I've got fuel at the injectors but still no starting. I've tried endless pump timing positions and all I get is slight smoke but no start.
I'm running the ALH 2-piece pump pulley. Anyone got any tips for setting the timing?

you 100% on the pumps tdc?? keyay should line up with #1 injector line fitting.. between 10 and 11 o clock on the pump shaft..
if off there, or say 180* off, you would get this...
since the pully hub has to be "pressed" into place, no key, id look there.

x2 Sounds like you're injecting on the wrong cylinder. You can pull the lines and crank it by hand to see when the fuel starts to come out of the delivery valves to determine which one is firing when...

Yup, if you are getting smoke the fuel is making its way in to the cylinder and injection timing is not likely the issue. They will runat the extremes of the spectrum.

I've tried turning the pulley to each pump position e.g. A, b, c, and d and I can't get the thing to even cough, I'm worried that with all the trys to start, im litterally just filling the bores with diesel as I'm starting to get a black oily mess coming out of the turbo outlet ( downpipe still off at this point ).
Could it be that I've just got a dud pump? I'm considering building up my own mtdi pump as at least then I will have the correct timing marks? I have a 1.6td pump and an Alh edc pump to hand.

Got it running tonight!! It turned out I had the pulley hub fitted 120 degrees out! Got t set in the correct place this evening and after a little fiddling about with the two piece pulley it fired up on the second attempt!!
Went out for a test run and OH MY GOD! I had my k14 set to 24psi off the wastegate when it was on my previous idi Td setup and with it unadjusted and stock Landy 300 tdi fuelling it's making 30psi and one hell of a lot of torque!!
It's too dark to really see how much smoke I'm getting, but it starts and runs so well I'm stoked that I've actually managed to sort it and get it running myself!!
Cheers for the advice tho guys..

Glad to hear it! Sorry I never replied to your previous reply! It went under the radar somehow.
The only problem with combining the 1.6 or 1.9 IDI pumps and the DI internals is you are then left without a DI specific internal throttle lever. It will not be able to move the fuel collar enough to fuel properly. It will run, I've done it, but it won't be anywhere near the abilities of the Rover pump even with heavy modification.
30 psi is a little high for that k14 to sustain, so I'd take it a little easy with those boost pressures! LOL.
If you wouldn't mind, and if you haven't already, can you please navigate over to the M-TDI thread in the FAQ section and update it with your current setup and parts used to obtain a running M-TDI?

ive been enjoying driving my m-tdi so much ive not found the time to post!
cold starting is amazing! coldest its been here in surrey has been -3 deg C and it starts with no troubles, ill post a vid of the cold start of this 1z and my old idi for comparison.
I have just over 600 miles on my conversion now, a few niggles had to be sorted and a nasty oil leak but all seems well with the landy pump so far..
although, it has a slight lope at cold idle and until the engine is warm i get a slight blue haze from the exhaust when the engine is revved to say 2500 and held there. im not sure ive got my IP timing 100% yet. could timing be the cause?
ive had to wind the boost down to 20 psi, as my little k14 was starting to complain
i have had a fiddle with the LDA boost pin as it was in the supposed "stock" postion (couldnt see any other wear lines on the ramp surface) so i turned it 120 deg and now have much smoke!
i havent given up making my own m-tdi pump work, as you say 8v, the throttle lever doesnt move the collar anywhere near far enough. i tried winding the max throttle position screw out all the way and i felt that the lever inside the pump was binding
i will get some pictures together and post up list of parts i used etc in the FAQ section for anyone else that needs help in doing this awesome conversion!

whats the smoke smell like? sounds more like oil vs fuel at that color...
me loves my landy pump... ive been running 18~21 psi on mine... less then that it surges... and 28psi scares me so where ive run it as it feels great..
mine no soot... but ive never played with the fuel screw yet... or boost pin... im happy..

Why does it surge with LESS boost? The k03 only ran 12psi on a good day, stock in the A3's. 28psi? Jesus Christ, I am surprised nothing blew apart. Do you inter cool your 20 psi?

ahh yea.. got big ol aluminum one... not huuge.. but 2x stock size.. wide as rad.. 1/3rd to 1/2 its height.... look for front grill pic..
and yes it surges as wastegate wants to open... and less then that at 65-80 it surges unless 18-21psi.. rember i got controller to play with as i drive...
28psi... = more then 78mph in 3rd... that a tad over 6k at 18-21psi... will pull higher.... imo stock tdi turbo is my holdback... need big old one...

I think your Tachometer is off sir. You're telling me you spin your K03'd AHU above 6k RPM?? I do not think these pumps sustain injection at that RPM. Unfortunately, I call BS.

gps (78mph x multi attempts)..... tiresize (195/50-15).... gear ratio (stock 98 tdi jetta 02a, 3rd gear)... tach/speedo no count... "mike" did the math...
beleive me... you think yours bad in wet... try mine..
my tach hits 6k... then drops to 4k and keeps going... and well speedo from day one was off... very off now... my tach 4k is ~55 in 4th,~ 73 in 5th.. learned that long ago due to speedo offness..
