Have I missed anything?

[CROW T. ROBOT]

Just joined, love the site so far! A customer of mine gave me his son's old 86 Ranger, 2.9 of course and as it's been sitting for a few years I've kind of made myself a checklist of stuff to replace and inspect before I even think of firing it up.
Any easy way to drain the tank on these things, or should I just drop it? And after the fuel filter and usual tune up bits, anything else I should look for? The previous owner said the throttle stuck a bit, especially in the cold so I guess I'll start with the cable first.

One easy way to drain the fuel tank is to remove the fuel filter, take the inertia switch connector off and run 12v to one of its two connector pins (try both, only one will run the pump - the other is the feed from the FP relay). If you use a jump-start powerpack, the black lead needs to go to ground, of course. If you use the truck's battery as your 12v source, ground is already there. Myself, I used the QD at the fuel rail to let it run out of there into a bucket. I already had the QD disconnected for an engine swap.

The inertia switch is located where the passenger's left foot toes rest, under the carpet.

You could also simply ground the Self Test connector pin shown in this link and turn the key to Run (that will provide a ground for the fuel pump relay for you and make the pump run off the truck battery). http://www.fordfuelinjection.com/?p=6
Scroll down to the "Fuel Injection Harness Power circuit:" and you can see which pin on the Self Test connector needs to be grounded to do that.

Self-test connector looks like this:

_ _ _ _ basically a 4 pin row
_ _ and a 2 pin row, but centered under the 4 pin row (couldn't make the dashes line up like it should be. Just look at the link to see the connector.

Ground the red pin.
