Ok guys so I got a chance to do a compression test this weekend and also mess with my injectors. Ill list my compression readings first and then talk about my findings on my injectors.
Compression Readings.
Drivers side front to back.
2. 300 psi
4. 400 psi
6. 300 psi
8. 390 psi
Passenger side front to back.
1. 350 psi
3. 300 psi
5. 340 psi
7. 345 psi
All compression readings were done 3 times to get an average. Motor was cold when compression test was conducted. Would you consider this motor junk?
I also took some time to mess with my injectors. I noticed that when the truck is cold and wont start that only 1 injector has oil pumping out of it ( injector in cylinder 1) when cranking the motor to try and start it. Is that normal or should they all be pumping when it’s trying to start? Then I plugged the truck in overnight got it started in the morning and looked at the oil coming out of the injector deflectors now and it was barely coming out of any of them until the motor warmed up. After 10 mins of running I still noticed 2 injectors had zero oil coming from them. I went on to unplug the electrical connection from each injector one by one and it appeared that only four of the injectors were working.
Here's everything I have replaced on the truck all new glow plugs new GP relay (Stancore) new UVCH gaskets and wiring. Two new batteries new starter. The truck still will not start unless it's plugged in or pull started. Starts fine once its warm and has been running but won’t start 24 hours later and this is in the summer time or winter. Glow plug system is working fine am also getting an amount of white smoke out the exhaust while starting when not plugged in. The oil in the HPOP reservoir is at the correct level have checked it on multiple occasions. There is also oil in the ICP sensor but does not make a difference in starting with it plugged in or unplugged.
The truck is now getting harder and harder to start even if leaving it plugged in overnight.
Took some ICP readings this weekend also.
Starting where truck won’t start is 2000 PSI.
Start up 700 PSI with a duty cycle of 30% (This is with the truck actually able to start)
2000 RPM had a reading of 2200 PSI with a duty cycle of 35%
2400 RPM had a reading of 2260 PSI with a duty cycle of 19%
2500 RPM had a reading of 2400 PSI with a duty cycle of 18%
3000 RPM had a reading of 2655 PSI with a duty cycle of 45%
Sorry for so much information just trying to get this figured out.
Thanks
