I have a 95 7.3l PSD with new glowplugs installed. Engine cranks but doesn´t start when cold.
Any idea what went wrong?

How much is it driven? If it is old fuel in the tank from the fall or summer then the fuel has probably gelled in the cold. In the states it is typical to run "winter" diesel which is about a 50/50 mixture of diesel and kerosene.

it is because you need to hit the gas pedal a few times then turn the key. i have the same problem with my truck.

Thank you frogger!
You really think so? Sounds like air in the fuel line?

I thought maybe a blown glowplug relais is the reason.
What you think?

Maybe that is the problem. If you put new glowplugs in then I do not know. I have to press the gas a few times before my truck will start when it is cold. If I can find out what hte problem is I will let you know. O.K.

are you plugging the motor in at nights? Up to the 01 trucks they were pretty finicy below 25 dergrees, Also partially plugged fuel filter, An already flooded engine due to cranking speed, tired crank trigger or low rail pressure due to low output fuel pumps. Using the trottle during start up is a learned experience with the power strokes, they each seem to be a little different and cold weather really brings that out. Good luck

Ok some PSD tech, first the PSD has a electric throttle so pumping the peddle shouldn't change shit with the key off. With that said if the throttle transducer is going out all kinds of electrical stuff starts showing up. If the truck is hard starting it's very normal on older PSDs ( I plug mine in anytime its below mid 30s) If you didn't check the glow plug relay? I'd start there !! Use a test light when the key is turned on it should show power across the relay for up to 2min. If the relay is only comming on for a few seconds , there's a problem between temp sensor and computer.The relay is a very common failure. note: it's not an ordinary starter relay, you have to pony up for the big dollar GP relay. Next the good ole CPS ( crank position sensor) it's common for CPS failure when cold, below 20, then it works after it warms up. It's a very fustrating problem. Next and last common PSD starting problem, batteries, they may seem to be alright. PSDs really like to be turned over at a high rate ( it's so the high press oil pump can pressure up the injectors) so we all know batts don't like the cold and if their starting to weaken at all you'll be chasing ghost for days. If the batts are over 3 yrs old and everything else checks out, change them. Good luck Pepper

Your right Ken, some tech that we learned from my 2000 I had.

If the oil in the engine is low, it will not build up enough pressure to open the injectors...

I bought a lemon of a truck before we moved up here, and from Sacramento to Boise pulling a 25' enclosed trailer, it burned 9 quarts of oil:darn:

That being said,after we towed the load here, pepper and I started driving down the street with it, and it died and would never start again...

Towed it to the Ford dealer and found out that it was 9quarts low on oil, they said they poured oil in it and it started right up.....:darn:

I was wondering why you said my truck started so nice. I don't even bother with the grid heater when it's 40*... just fire it up. :thumb:

When I was in AK our fleet we has about 10 00-01 F-350s all diesels. Forget to plug on in when it was -15 and no way it was starting.. the starter wouldn't turn the engine over fast enough.

Damm Dodge owners,
The PSD sure looses it's luster in the cold weather. Another thing I thought of: This works for all Smokers if you run additive when it's cold it lowers the combustion point of the fuel making hard starts a little better. :cool:
