99' 4.6L Cranks but won't start
My 99' 4.6L has close to 200k miles and has been a great truck ever since I've owned it. I've been having a problem lately where it'll crank over and not start. But if I turn the key to off and back on again a few times I can get it to start and once it's started have no problems. Now... it won't start no matter what I do. I've replaced relays, put new plugs and wires on it with no success. Could this be a failed fuel pump even though I never had a problem while the truck was running, just at start up? I also checked for fuel pressure while cranking and had none. Please help.
Thanks,
Robb

My explorer did the same thing, changed fuel pump and no problems after that. The pump has a sock/screen on the fuel pickup. If it gets clogged it is hit or miss on fuel getting to fuel rails
