glow plugs? Live to pump? pump primed? all of these would contribute to a no run situation! hope this helps

prim the pump??

Yup!, crack the nuts on the injectors and turn the motor over until diesel starts to seep out of each injector. a lift pump would would help here too.

Try to pullstart it. I´ve had some troubles in my days with cranking and cranking even though I primed the pump and what not. And they still don´t start. And when pulled they always come to life. Sometimes the starter doesn´t manage to get the last air out of the system.

glow plugs?

96jetta · « **Reply #6 on:** January 04, 2009, 03:11:18 pm »

oh ya ive done that and i got fuel in all the lines. but i cheacked the power to the glow plugs and i got a steady 0 DCV

. thats what i assume the problem currently lies

Check glow plug fuse.

check blue/white wire connection on temp sender for glow plug relay.

check glow plug relay.

if you really need to start it right now, run a jumper wire from the battery positive to the glow plug bus, count to 15, then disconnect the wire and run inside the car and crank it over.

probably the glow plug fuse though. Does the light come on?

does it have a block heater? plug that in for a good half hour or so and that should help. 300+ psi compression with glow plugs should start down to -5C without much trouble. maybe a lumpy idle, but thats it. when its cold things shrink, and fuel lines harden, so usually air leaks into the system, compounding the problem...

ya the glow plug light still comes on. and i tryed pluggin in the block heater it caughed then died again

check the fuse.

96jetta · « **Reply #11 on:** January 04, 2009, 03:26:11 pm »

its like #15 right? the pne for engin electronics?
cuz that one is good. but ive heard of a glow plug relay and m tryin to find where that is but no luck yet

vanagonturbo · « **Reply #12 on:** January 04, 2009, 03:29:18 pm »

I know this is probably a stupid question, but what year is the car you are working on?

96jetta · « **Reply #13 on:** January 04, 2009, 03:31:35 pm »

96 it was made in febuary if it makes a difference

Just to avoid confusion... the yellow light on the dash has nothing to do with the glowplugs having power (unfortunately :wink:) and the engine management fuse (if equiped) is not the glow plug fuse.

The glowplug fuse is the big silvery strip in a small black plastic box bolted to the firewall to the left of the brake booster... has two big red wires coming out of it.

On the MK3s there is sometimes another glow plug fuse in a pink fuse holder at the top of the fuse panel on the drivers side under the dash.

The glow plug relay is also on the fuse panel... it's a tall rectangular box on MK2s and a fatter square box on MK3s.

Regardless of chassis the workaround from a troubleshooting perspective is to run a heavy wire from the positive terminal on the battery directly to the copper glowplug buss bar for 20-30 seconds and then try to start the car.... this bypasses both the relay and the fuse.
