    6.9 cranking but no start

    I have not tried the block heater truck yet. I was hoping that it would start with out that. Will attempt the block heater tomorrow morning and let it sit for a few hours while I am at work. also I did make sure the fuel is pumping. You can smell the fuel at the exhaust pipe

    6.9 cranking but no start

    I've pulled out 4 of 8 and four of them so far are bad. I'm going to have to wait till tomorrow to get the next 4 out. That one plug spot filled up with water. So I had to blow it out and shoot some more wd-40 at it

    6.9 cranking but no start

    So I wanted to come on here and give a quick update on what @IDIBRONCO and I tested and found out tonight. @IDIBRONCO first started at the lift pump to verify pressure. This was good. Then checked at the Schrader valve. Again good. Then to injection pump. Finally he cracked 7 of the 8 fuel lines...

    6.9 cranking but no start

    @rhkcommander I was wondering about the Injection pump. Is it possible to have some fuel coming out of the injection pump and not be bad? If so does that mean its clogged and needs cleaning or if its a little bit. If as you say your supposed to get 1500psi and be gushing out. When I originally...

    6.9 cranking but no start

    @rhkcommander, I have removed that wire before and run a line from the battery to the FSS. I hear a audible click from it. Also have tried the schrader valve on the filter while cranking and fuel comes out at a good pace. Im wondering since im not getting any exhaust smoke from the pipe either...

    6.9 cranking but no start

    So even though I am getting fuel to the top of the injectors nothing is getting into the cylinders? Like I mentioned previously I did crack the hard lines on top of the injectors and get fuel coming out of the top. Does this mean I need to replace the injectors? Again sorry for this I'm...

    6.9 cranking but no start

    This afternoon I tried to crank the engine over as i did before foot to the floor. Again no start. I did check to see if there was smoke of any color coming from the exhaust tip. Not producing smoke. Im thinking I might try replacing all the glow plugs this time. Since I have never removed them...

    6.9 cranking but no start

    So I was wondering when attempting to bypass the glow plug controller. Are you supposed to disconnect the controller from the harness? I have the one that screws into the back of the block.

    Hey everyone, I'm new to diesel engines and I recently bought an 1986 f250 with a 6.9 idi non turbo from an old farmer. My father had one of these when I was younger. The man said he had last had the engine running 2 years ago but was too old to figure out what was wrong with the truck. Didn't...
