my 87 6.9 diesel is hard to start after sitting for a while, maybe a week. I have to crank it for a minute or two before the fuel reaches the engine, then it starts. Any thoughts as to why this is happening and a fix. Thanks

90% of the time its your return lines. They are the lines that go in between each injector. Most are old and dry rot with time. Go get a kit, and install it. I bet you good money it will cure your problem.
