ok a lot of people have something about this but not just like this.

Ok so the truck has been getting harder and harder to start....now it barley starts
once it starts it runs fine full power good mpg no issues.... this happens even when the temp is hot out it did it when it was close to 100 the other day
i changed the gpr and it is good
the glow plugs ohm out good and there is voltage to the plugs and seems the glowplug system is good
i changed the cmp and it started up first try but went back to hard starting the very next time i tried to start it
i pulled the injector pressure sensor no help
the hpop reservoir is full
the fuel bowl is full
even though i changed the cmp with a bwd one not a autozone one it still gets no tach when turning over is that right?


Im stuck now and dont want to keep throwing money at it...any body got some help?

 

Try cleaning the IPR

 

and i assume i have to pull the whole thing out?....can i do that without pulling the bowl out?

 

think you have to pull the fuel bowl to get to the IPR

 

Ok I think it is all good now....the truck seemed to be turning over fast enough but I guess it wasn't fast enough for the hpop to spool up right.......i noticed one of my batteries was over ten years old so i swapped it with the one from my hot rod pick up and wouldn't you Know it fired right up. It fired right up again this morning and it was only 55 degrees (only for San Diego) so I read a little bit about it and hpop trucks really need to have very healthy batteries in them.....I may also change to a gear reduction starter to get better engine speed when starting......thanks for the help

 

They need healthy batteries and starter but I wouldn't do a gear reduction if it was me

 

Look at your fuel lines too. Mine did the same thing, then ended up cutting out when it ran.. Turned out to be a sucked flat line.

 

What is a CMP , HPOP , BWD and IRP ? I am new to diesel pickups and have a 96 7.3 that cranks but won't start with out a little shot of eather. I put in new glow plugs and relay but still no help. Has white smoke when cranking.

 

Hpop high pressure oil pump, bwd is a brand of parts, IPR injector pressure regulator
