I hope someone can answer this glow-plug related question:
The owner came to me with a starting problem.
The primary complaint is difficault starting.
Once the engine is started the everything is OK.
Here is the info I can provide:
1. There are no DTC's
2. The timing is near the center line on the timing graph
3. GP resistence are all less than 2 Ohm (within 0.4 Ohms)
4. Static timing is dead on (crank, cam & pump pinned)
*Befor the owner came to me he has installed a new starter.
* Battery holds a full charge and the grounds are clean
Here is where things get interesting:
Once the engine does start it will issue a plume of white smoke and idle rough for about 4-5 seconds then run smoothly. Performance is very good. The "Stealership" replaced the injection pump ( 8 months ago)and the problem persists.
Today the intake manifold was removed and cleaned (cylinder head ports cleaned too).
The engine will crank 20-25 seconds then finally the engine will start and sputter to life.
I replaced the engine temp censor (ETC) still the starting problem persists.
Then I disconnected the ETC electrical connection and let the glow plug perform the full 20 second duty cycle. The engine starts PERFECTLY!
This test resulted in only one DTC (ETC open /short to ground related).
I then went to check the GP relay and this is where this tale of woe gets really interesting.
ETKA lists this relay (marked #180) for position 10 on the relay panel.
When I went to check the relay panel there was no relay in position #10 but neither is there a relay socket for the relay to be inserted.
There is an open hole ...no wires, no leads and no relay socket! *** ????
Someone out there has to have an answer for this one...please let me know.
TIA
