    valve covers need to be removed as they are underneath them .After that it is not too hard.

    Check the relay first.
    It's by the fuel filter.
    And make sure that it's got good batteries.
    It will not inject fuel till it hits around 500rpm.

    i am assuming that it is safe to say that u dont hop right in and try to start it up ... you do let the "wait to star" light light turn off right..... also are you plugging your truck in at night for the engine heater.??? if so then you should not have any problem at all with only 44000 miles on it. after having mine (2000 7.3psd 4x4 dooley )plugged in for only 2 hrs i can start it up and the heater can be blowing warm air within 7 minutes at most. If the glow plugs are bad ive heard it it costs alot to have them changed but thats only what i have heard. Keep us up o date as to what it is.

    similiar problem recently

    I have a 2000 f350 7.3 psd. just a few weeks ago my engine would not start. It would crank and sounded a little sluggish but would not fire up. I even tried adding jumpers to one of the batteries but no luck. In the long run I ended up replacing both the batteries and the problem fixed itself. Initially I only replaced the bad battery but within a week and a half the second battery went belly up also. What I learned is if one battery goes down you will need to replace both. Good luck :D :waving:

    dealer called today and said that all the glow plugs checked out good. But he also said that 2 codes were coming up one was to much fuel which than he asked what kind of chip/programmer i had in it. The other was the relay. I told him i had no problem with it last year with the chip so he said they would do some more tests on it most likely its just the relay.

    You told the dealer you had a chip and they didn't void your warranty? WOW did you get lucky. Who is the dealer?

    At least they are being honest with you. Most dealers will keep throwing parts at the problem till they accidentally stumble upon the cause, because they do not have dedicated diesel mechanics. Did they R/R the gp relay? What was the resistance Ford got when testing the gp's? And where exactly did they connect the probes to do the tests. The gp's should read .9-1.2 ohms when measured at the valve cover gasket connector.

    Just to be sure I understand your problem correctly; If you let it sit for lets say 1/2 a day without the block heater plugged in, it will not start. And if it is plugged in you have no starting problems. Considering we live in the same area I will assume you have had similar weather as I have. I have not had any nights or days yet this winter where I thought it was a necessity to plug my truck in due to low ambient temps. I have not had any starting problems so far. I still think it is a gp circut issue.

    That is a very possible cause. In case nobody ever told you, always buy your diesel at a "high volume" station. One that serves a lot of trucks. They will have a high rate of turnover for the fuel in their bulk tanks. Brand of station does not matter nearly as much as the quantity of fuel they sell. I have gotten bad diesel three times within 18 months at a low volume station that was owned by one of the two largest oil companies. I do not know the centane specifics on diesel but I am sure you can find it on the net. You probably should change your engine oil, fuel filter, and run a lot of fuel conditioner for the next several tanks.
