F350 Turbo Diesel doesn't respond when I turn Key

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

Okay, If this noise happens when you turn the Key to start, your Starter Relay is bad. Now the other possibility is the Glowplug Timer. When you start a Diesel there is a pause in the initial cold start. You turn the Igniition Key to Run, then let the Glowplug Timer cycle. This cycle sound will be a series of clicks which also may cause the lights to dim.

The glowplugs absolutely must warm up to start a cold diesel engine. There should be a light on the dash which either goes off when the glowplugs are ready or a light will turn on when they are ready. It is only after that activity that you will turn the Key to Start.

Since Diesels take more power to Start, there are 2 batteries. As with a single battery system, every connection must be clean. If the Glow-plug Timer is working and you only get clicks by turning your Key to Start, check the things I said earlier. Your Starter Relay and the big cable connections.

If after all of that, the engine will not turn over and only clicks, jump the Starter Relay with 1 cable from a jumper cable set from the Positive Battery cable post to the Starter Relay on the Starter wire connector. Make sure the truck is in Park or Neutral. If the Starter jumper cable sparks and the Starter does not turn, the Starter is bad. If the Starter spins it confirms the Relay is bad.

I hope my Solution gets you going and that you consider this helpful.

my 04 ford 6.0 doesnt start some times but if i turn the key on for 20 seconds then turn key off and do it again for 20 seconds and the 3rd time it starts but dont crank it over till the 3rd time its been working for me

Are you waiting after turning ignition key on before actually moving key to start position? My diesel I turn key to 1st position;bells and lights;if engine is cold an amber light that looks like a lamp filiment comes on...wait until that light goes out before engaging the starter.

that fuse powers pcm fuel heater and some other things. when the fuse blows the pcm shuts down. causing it to not run. usually its the heater that is bad. it is located at the back driver side by the fuel pump. you can unplug it and see if it starts. if so you will need to replace the heater

Possibly the fuel injector moduel

check the baterries in the remote key

This sounds like a problem in the fuel shut off circuit. When you turn the key on, it energizes the fuel shut off solenoid on the injection pump. When you turn off the key, power is removed and the pump is moved by spring to the fuel off position. Check for power at this terminal when you are having a problem, ( with the key on) If no power then I would check the wiring and connectors from this connection to the Ignition key. I believe it is wired direct. That can be checked at http://www.alldata.com/products/index.jsp

subscribe3 and get a wiring schematic for the car and see if it is wired direct to the ign switch of from a relay, I am sure it is a connection problem if you have no power.

A 1.7 diesel even if turboed, is dead slow in any vehicle let alone a van. Enjoy the fuel economy

good luck

check ur fuse box and look for any blown fuse that starts the car

Your help was of no value, the technician had never seen the inside of a Porsche. thanks anyway
