    What plow? Any hoses leaking?

    edit

    If it is new, why not take it back in for warranty work?

    bad lift piston to. it may not have been packed right and is leaking,

    your lucky thats the only issue, a buddy of mine in nh installed one on his bosses truck last year or so, lifted it up to test it and all the weld on the head gear broke and the plow fell off the truck. fisher replaced it right away like a good company, he hooks up to the new one and the same thing happend. some one was sleeping at the factory and only tack welding. :nono:

    it worked for a little while before not "staying up"....now the truck wont start this morning...getting power and boosted it as well. not sure if the two problems are related? could be the starter wire, need to crawl under as soon as it warms up a little bit !!!

    not cranking period !!! the battery is good, but get nothing when key is turned....Just wondering if the plow issue could be related to the truck not starting....Starter? Wire to starter? Solenoid? she's going back to the installer hopefully today !!!

    well it could be that the plow was shorting out with a bad ground and friend your computer. if thats the case i would just light a match and walk away or it could be that the ignition is junk im not sure to tell you the truth

    It is highly unlikely that the two problems are related. If it's not cranking they are quite a few problems it could be. If your truck has a starter relay in the relay box you could try swapping that with the horn relay. It could be the starter or the starter solenoid. It could also be an anti-theft problem. Also an ignition switch problem. Or a problem with the computer. The best way to diagnose is to jump the starter solenoid. If you are unable to do that, or do not know how you need to get it to a shop.

    Assuming your plow is not leaking fluid the issue is probably caused by the S1 valve or coil. It would be one heck of stretch to say that the S1 coil caused your truck not to start.

    Those year f150's are known for having the copper lugs on the power wire going to the starter rot off. Thats my bet.
