hi im alex could i have the last 8 of your vin please
ok thank you, ***** ***** fuel pressure been checked while trying to start?
how long does it take to start when its hard starting
yes that is what it sounds like to me, especially with the white smoke, have you tried pumping up the hand primer and see if it starts up after sitting?
there is also a check valve in the hand primer pump
ok well i would let it sit and then pump up the hand primer and see if it starts this is a terrible fuel system, lots of problems with the filter head
does this have a grid heater?
how about if you put a battery charger on it and then crank after sitting, i have seen it where ECM voltage will dip below spec and cause a hard start
no it wouldn't necessarily happen every day only after sitting and the battery's go down in voltage a bit, it only takes about 1v low to cause the ecm to kick out, the rpm runs up when it surges? has it always did this at start up or just since the hard start?
has the egr valve been checked for sticking? that would cause hard starting and the surge, and would be worse when cold
yeah thats night right, hard to charge some one when you didnt fix anythng
for hard starting #1 is ICP pressure #2 fuel pressure #3 battery voltage #4 egr valve for sticking and #5 grid heater malfunction
i will attach the hard start/no start sheet
here is the hard start no start sheet, and performance sheet as well
If you have any questions on the sheet let me know it is what any international dealer would use
another thing i was thinking was if the oil is running out of the front cover, if you let it set over the weekend and you pull the oil temp sensor which is by the high pressure pump in the front cover oil should run out, if it dosent then you have a leak in the front cover seals and that is causing the hard start
do you need any more help with this?

removing the front half of the front cover and replacing the o rings and seals
