    Someone tell me how to upload photos, I complained a long time ago about the change to how the site works or doesn't. Or Email me at grancito2@hotmail.com for the photos of the injector nut and the OPS jumper lead. The photos are ready to send.

    I am going to try and share Gracito's pictures and notes below.

    "The first photo shows the nut on the injector line, loosen that a half turn or less, and crank the engine, if some fuel comes out, then the IP is injecting fuel. The other photos show where to jump the lift pump. The green wire is what I added, I bared the wire at each end and put one end in the "eng 1" fuse hole and put the fuse back in, and the other end in the far right hole of the lift pump relay. The reason for the OPS control of the lift pump is only for safety, to stop the pump in case of a crash. They fail a lot, so I will take the risk and bypass it."

    Thanks very much, Grant!

    I saved the individual pictures to my computer's "pictures" file. When you reply on this forum with a message, there is a toolbar at the top of the message box. 3rd thingamabob from the right is "Insert Image". Click it, select "from computer", "select files" then from your computer's pictures file double click the picture(s) you want to use. Click "upload". Post to the forum.

    I see an error in the connection at the relay that I wrote to ripnrun, I was standing beside the truck. Connect to the passenger side rear pin.

    It will probably be this Saturday before I can check the injector lines. It's dark when I get home from work.

    The pmd that I just put on is not new (I thought it was) so I went ahead and ordered a new Dorman pmd from Pensacola Diesel. I'll get that installed this weekend too.

    The reason I am posting today is that I had asked whether the black plastic diamond-shaped covers on the underside of the pmd should be removed. Pensacola Diesel told me I could leave them on.

    I believe the ip is pumping fuel. I put the new pmd on and did manage to get the truck started. It ran like a champ. However, it is still very difficult to start (cranks but won't start). I am going to try the ops bypass that Grancito showed. Could the ops be making the truck difficult to start or what else could it be?

    It seems like my ops is fine. When I hook up the jumper cables, everything is good. I'm not even getting codes for the 1st time in a long while. I think all that is left is to replace the batteries. Thanks very much to you guys for the help.

    Now I'm back to battery shopping and I am thinking I will go with Interstate batteries. There is considerable difference in price between their "biggest/best" and their "biggest/best deep-cycle". Do you guys use deep-cycle batteries?

    Good that you have eliminated possible problems. Deep cycle batteries are designed to survive being drained down a lot in marine and camper applications, they often lack cranking current for starting, and not worth using as a starting battery because of the price.

    Thanks for the info. My current Optima batteries are the expensive deep-cycle type. They have always recharged/cycled as advertised but maybe the reason I have had difficulty starting dor a long time is because I need more cca. I am going to try the 800 cca Mega-Tron Plus from Interstate.

    Any body know whether battery terminal cut off switches are worth using and which ones are the best?
