I have 95 ford 350 turbo diesel it will turn on great in the morning when cold .when I shut it off it won't start back up again when hot

SOURCE: ford 2002 f250 7.3 diesel won't start on cold

It probably is your glow plugs which are controlled by the cold start relay. They burn out over time. This is normal. Haynes Diesel Engine Repair Manual, part 10330, will walk you through the diagnosis and replacement easily. It's about $20. Hope this helps.

started car had only just gone around the corner and heard a burst sound then hissing thought it might of been radiator hose. stopped car checked main radiator hoses took radiator cap of released pressure ,but hissing continued sounded like it was coming from mid part of engine any ideas what it could be..

Intake Air Temperature Sensor (IAT) - REMOVAL & INSTALLATION

5.8L and 7.5L Engines

Fig. 5 Typical IAT sensor mounting-5.8L and 7.5L engines

1. Disconnect the negative battery cable.
   
2. Detach the electrical connector from the IAT sensor.
   
3. Remove the IAT sensor from the intake manifold.

1. Installation is the reverse of removal. Tighten the IAT sensor to 12-17 ft. lbs. (16-24 Nm).

The first thought that comes to mind is a high pressure oil leak. The injectors have a snap ring on top that sometimes becomes detached and it will create these symptoms.

When you depress the brake it sends a signal to the PCM (Powertrain Control Module) and the PCM increases the idle because it predicts you are about to shift into gear. If the truck has a high pressure leak inside the engine it will have a hard time building pressure initially and once the oil warms and thins out the High Pressure Oil Pump cannot hold the pressure and the oil leaks faster because it is thinner.

You may have a leak around the pump area which is under the turbo also. The IPR which is the regulator that controls the oil pressure may also be bad. It is directly under the turbo as well. The IPR is located under the turbo on the High Pressure Oil Pump cover. You stated the seals were leaking on the IPR itself? If the orings are damaged or if the screen in the end of it is collapsed or even punched through with a small hole it will need replaced. Screen damage is usually a sign of debris entering it from either dirt from a previous repair or something is coming apart inside.

Make certain you have clean oil and fuel filters. Yor may want to check fuel pressure as well. It should be somewhere around 55psi on acceleration.

Additionally, I suggest check for voltage at the connector on the fuel pump. The pump is mounted in the filter housing on the frame and the connector is at the front of it. The pink and black wire should have 12 volts with the key on for about 30 seconds. If the pump has voltage but is not running, then your pump has failed. If there is no voltage then check fuse 2.40 in the central junction box. This is the fuse that feeds the inertia switch through the fuel pump relay. I have included a fuse box layout and a wiring diagram (click over images for zoom)...





Additionally, will need to scanned the PCM to know if some fault code is stored there.

Keep us updated.

there is no wastegate on a 6.0l turbo. its a variable geometry turbocharger and doesn't need it. i have never seen a turbocharger cause a misfire, the turbocharger is most likely not your problem. if you didn't clean the intake out when replacing the egr valve there is a really good chance that the egr is bad again. also, a bad egr cooler can cause repeat egr failure. also, fuel injector control module is a common cause for misfire
