turning on fuel pump - '96 E150 Sign In

I'm trying to get the old gas out of a 1996 Ford E150, 5.8L that has been sitting for 9 months. I got the fuel line disconnected from the filter, running into a jug, and I'm trying to pump it out using the van's fuel pump.

The FSM says I can turn it on by putting a generic scan tool into "output test mode" by first entering the "OBDII system readiness test" and then entering in a string sequence that will switch it into this mode. The problem is, the Innova 3130e that I'm renting from Autozone does not seem to have either of these things.

Do I need a different scanner? If so, which one? If not, what do i do different?

Of course it won't. You are comparing ToysRus stuff to professional tools. The scan tool you needs starts in the range of $5000.

The easiest way to to pull out the fuel pump relay and jump the #30 and #87 sockets.

Make a short jumper wire with a blade connector at each end.

Hmm, don't know where to get those blade connectors. Can't I just use a paper clip?

No, it will overheat.

You can get wiring terminals at any automotive or hardware store.

Is there a minimum wire guage I should use then?

14 or 16 would be good. Finding a small piece of wire shouldn't be hard. It only needs to be about 3 inches long. Cut up an old extension cord if you need to.

The paper clip has a plating on it that gets real hot real fast.

Those look like crimped and not soldered terminals, so I'm guessing that's ok, but are you saying that if I just cut a piece of 16 guage wire from an extension cord, I can stick that in there without the terminals?

No, I'm not saying that. I was just looking for a way not to have to go out and buy wire just for a couple inches. You're making this a lot more complicated than it needs to be,

Ok, so you're saying the terminals are essential whether I buy wire or scavenge around the house for it?

Make sure you jump the right terminals in the relay socket or you'll be buying a new PCM.
