After replacing the expensive commercial battery in my diesel tractor every couple years I bought a little maintenence charger for $ 60 bucks that automatically keeps the battery topped off all the time. so far its already paid for its self

I`m still a wannabe diesel gurru, but I know in a gas engine white smoke is an indication of coolant entering the combustion chamber. Hop[efully thats not your case, I will be interested in seeing what you find out.

My Haynes manual shows a "Parker access valve" with 1/8 NPT threads for checking fuel pressure @ the F/W seperator.Does anyone know where to find one ? all the local parts stores don`t seem to have a clue what I am talking about.

Thanks guys! is is great talking with people who know WTH they are talking about:cheers:

Mike, you have been a great help! and you just earned another premium member. I originally thought he had run it out of fuel, but with the lift pump seeming not to be running I wound up on a wild goose chase. some concern though. it is idleing @ 10psi, and under part throttle "2500" rpm it drops to about 7psi ?

Ok, just a quick question, Bleeding the high pressure lines, is that at the head? or on the injector pump side?

The engine cranks but will not start, and once the lift pumps starts its making 12-15psi, but will not shut off without disconnecting the battery? looks like my diagnosis is heading somewhere else now ? --- Update to the previous post... after cranking some more the lift pump is cycling correctly, but still won`t start, and there are no DTCs I was thinking he might have just ran it out of fuel since his gauge is not working, but I would think it would have tried to hit a lick by now ?

Well I put everything back together and left one of the access plugs loose to bleed the air out of the filter, and the lift pump ran continuously even with the key off. I had to disconnect the battery to get it to shut off

Yes it still has the stock lift pump. Just a little history behind this vehical. Right after he first bought it he had to have the transmission rebuilt at a local shop. About 5000 miles later the transfer case sheared off from the transmission while he was driving. needless to say he came to a violent halt in the middle of the road. after towing it back to our shop I found that the top stud on the case was broken off, and the tranny shop evidently did`nt think it was neccesary. after replacing the overdrive extension housing, and the broken stud we got him going again only to find that the speedometer had quit, and the fuel gauge worked intermittenly for a while then quit all together. I am a little baffled that the PCM has`nt turned the check engine light on, and my OBD 2 is not picking up any DTCs ?

Let me go check it n I will be right back --- Update to the previous post... OK, I had to wait for the "wait to start" light to go off, but it did give give 12v for 25 sec like you said. I have ran strait battery power to the pump and it makes 15-16 psi running. So this leaves me scratching my head again LOL!

Hmmm, I have been checking it lately just cycling the ignition on and off since I have the water/ fuel seperater removed to access the ECM. Initialy we began checking it with the engine cranking.

my sons 99 model died and would not restart, I have traced the problem back to the ECM which is only sending 8.9 volts to the lift pump. I have disconnected the pump and the 50 pin connector on the ECM checked for short circuit and everything is good. I then cleaned and checked the 50 pin connector reassembled and still 8.9 volts coming out of the ECM.I was wondering if anyone has seen this issue before ?
