• is there not some sort of sensor that dictates how long the plugs glow somewhere in the cooling system? i remember reading about it on vortex a while back. Reason being is that i just filled the cooling system today..

• crap.. either all four of your plugs are TOAST or its a fuel problem... its puffing so the fuel solenoid is getting power.. are there any bubbles in the fuel lines?
  
  OMG! you had the head off.. did u take the pump off too?? did you remove fuel lines!? maybe the pump just needs to be primed??
  
  I dunno shoving them out there
  
  If you jumped the plugs manually the timer would be by-passed..

• i got my gf to turn the key when i was under the hood just to hear if the cutoff solenoid was working and i can hear it clicking. i removed the glow plugs when i had the head off just to check because my warrenty info says they were changed in 98 so i was a little bit concerned when i seen that. there is over 100 000 km since the plugs were changed.  they werent burnt or anything to i didnt bother getting new ones.

  So your getting fuel, and you jumped the plugs and it still didn't go. You may have 4 dead plugs

• absolutely nothing happened, just cranked and cranked. i hope to god i dont have low compression.. it only has 279k its the lowest mileage jetta out of the 3 i have.

• CRAP.. hmm well.. it ran fine before right?
  
  you never did answer me about the pump and fuel filter.. are they full? and is the pump primed?
  
  it should run.. thats a piss off. what temps where you are?
• #22 by jettabrendan on 29 Mar, 2009 18:07
• oh sorry lol, i didnt take off the pump but i did disconnect the main line to bypass the fuel filter with a bottle filled with diesel, and the injector lines so i can remove the head. plus the fuel in the tank is old. i did what i thought was priming the pump by cranking it and getting someone to crack the injector tops untill fuel sprays out and close them.

• ok so lets see here, you have primed the pump, the solenoid works, you are getting fuel in to the engine..
  
  what is left? it must be wayy out of time...
  
  according to Vince's guide.. the engine will be hard to start if it is way out either way. I guess you need to play with the pump position some. to eliminate the timing... then next would be to pull Gp's and see if they are heating up. so much extra work for something so simple eh? sucks
• #24 by jettabrendan on 29 Mar, 2009 18:20
• yeah i read his instructions too, so much clearer than the bentley. i never did like following instructions in a manual, they jump all over the place. so yeah but its strange because when i got home today the first thing i did was re check tdc. i locked the cam, lined up the pump lines, tossed the belt back on. i think its -15 or 20 out today so its cold enough to prevent a diesel from starting with 4 possible junked glow plugs..
• #25 by 8v-of-fury on 29 Mar, 2009 18:21
• definitely Vince is the man. His guides are idiot proof lol.
  
  well, i hope all it is is 4 bad plugs.. and you dont gotta rip it down again. I tried my best.. but i got nothing left lol
  
  goodluck

  I'd be doing a compression check to see what you have to work with.  Everything else can be perfect but with low compression and being cold it's even worse.  I'm betting you have lower than necessary compression on top of timing problems as well.  But you need to know what compression is first, you just had the head off didn't you?
• #27 by jettabrendan on 29 Mar, 2009 18:26
• yeah thanks! i dont think its low compression.. it has "low" mileage for a diesel and it wasnt driven hard. i have all the maintenance records from the day it was bought till the day it was taken off the road. It has to be timing obviously and the glow plugs plus bad fuel. i had it going when i first got it, even took it for a short drive.
• #28 by jettabrendan on 29 Mar, 2009 18:39
• i also put in a 2 notcher instead of the 3 that was in there.
• #29 by 8v-of-fury on 29 Mar, 2009 18:41
• 2 notch is thicker than a 3 right? that would lower your compression.. not sure by how much.. but maybe enough??
