SOURCE: Hard coldd start.

On a 7.3 you have to take off the valve cover to test the glow plugs disconnect the wires from each glow plug and take a single wire run it from the positive pole of the battery and touch the tip of the glow plug. If it sparks it is good and if not it is bad. do this one by one. I have almost the same problem but mine is the icp above desired and here in belize nobody knows about 7.3.

The stuff that you replaced could have an effect on the starting of the vehicle. Take the diesel pump and injectors for calibration this should solve the problem.

SOURCE: Hard start condition and some times a no start

I have many fords in my fleet i have found let the glow plugs cycle about two or three time in a row before trying to start makes a big differance, they all start really hard. try that it might work better for you.

SOURCE: 1999 Ford truck 7.3 diesel, hard to start in the

if it is not getting power to the plugs witch it most likely isnt check your selinoids they are located on the top of the engine check and see if power is getting there and if that is all fine then you may be low on compression you can check this with no tools for blow by. when engine is running remove oil filler cap and look for puffs of white smoke if it is a consistant slight haze or little smoke that is normal but if it is poring smoke and puffing then you have one or more pistons or rings hurt. any more than a little stream of smoke is a culprit of worn out engine and needs rebuild. and if that is fine you may want to check your high pressure oil as that operates the injectors and is vary thick when cold you can also change this by taking an alen key and removing the small cap on top of the hpop (high pressure oil pump) resevior and sucking the old oil out with a seringe or another type of evacuator. then replace oil with new oil (same as what you use for engine) and then start engine run for about five minutes and do it again about three or four times. there is 3 qourts on the top of engine that run through the heads and HPOP system from navistar it was supposed to cycle throgh the bottom end oil but it never really does thats why when you change your oil and check it right after you start truck it is black again. i have more remidies but not to much more space message back if needed

BMW 320d e46 cranks but won't start.

check the cylinders compression, if below to 95 psi remove the spark plugs then check if wet with fuel ,
if this condition exist , It is very possible that you have to recondition the pistons, rings or cylinders

Hi does anyone know why my 2.4 tdci mk7 transit is hard to start 1st time in the morning once it's started its ok but when I try to start it in the mornings it a pig and when it does start I get blue...

This might help explain the causes and where the fault might lie! You didn't mention the mileage, if high it could be worn valve guides or seals!

Blue smoke is an indication of oil being burnt. The oil can enter the combustion chamber for several reasons.
  • Worn valve guides or seals
  • Wear in power assemblies (ie cylinders, piston rings, ring grooves)
  • Cylinder glaze
  • Piston ring sticking
  • Incorrect grade of oil (eg oil too thin, and migrating past the rings)
  • Fuel dilution in the oil (oil thinned out with diesel)
At cold start, blue smoke is often evident, and can reflect reduced oil control, due to fouling deposits around piston rings or cylinder glaze (which is actually carbon deposited in the machined cylinder crosshatching. These tiny grooves actually hold a film of oil, which in turn completes the seal between the combustion chamber and the oil wetted crankcase). Blue smoke should not be evident at any time, but it is worth noting, that engines with good sound compression can actually burn quite a lot of oil without evidence of blue smoke. Good compression allows oil to burn cleanly, as part of the fuel. It is not good though!

How do I replace the glow plugs?

  1. Remove the valve cover.
  2. Remove what's needed to gain access to the glow plugs.
  3. Disconnect the electrical connector and remove the intake manifold glow plug from the cylinder head.
  4. Using a deep socket or combination wrench, remove the glow plug from the cylinder head.
  5. Screw the glow plug reamer into the glow plug opening all the way in then out.
  6. Install the new glow plug.
  7. Reconnect the connector to the glow plug terminal.
  8. Replace the valve cover with a new gasket (if required).
  9. Reinstall anything removed for glow plug access.
Hope this helps. Good luck.

If i let my 7.3 ford diesil set 4 or 5 hour it hard to start again

A diesel uses glow plugs to fire the fuel when it is first started. If one glow plug quits working the glow plug controler shortens the time that the rest are on. If two its even shorter. If the wait to start light goes off sooner than it used to check the glow plugs.
Glow plugs can be checked easy with a test light.
Unplug a glow plug. (located on the head by the injector).
Just hook up a test light to battery positive (+) and touch the other end to the glow plug connector. If the light lights that one is o.k. Check all 8. Replace any that dont work.
If the glow plug system is working then check for fuel leaks. If fuel can leak out than air can get sucked in the fuel system and cause a hard start.
There is also a transfer pump on the frame rail under the drivers seat. This can be a issue if it fails.
When the key is first turned on this pump will come on and prime the system. You can hear it if you get close to it.
I hope this helps you. Re-post if you need more info.
