Fuel system and Trans

I have a 90s bronco II, I bought 2nd hand from a family member. Its a 4WD 2.9L V6 and I havn't even got it on the road. My family initially parked it because of trans probs and I bought it in the hopes of fixing it. Right now the transmission is supposed to have a bearing going out (they stopped driving it to ensure nothing else would go wrong). I can't seem to get any good resources off the net, or talk to anyone who messes with these (mitsubishi manual) trans. I was wondering if you guys had any tips and advice. The truck has been sitting for a while and the fuel system is messed up. I try to start it (it has an optima red top in it, so I'm not worried about the battery) and it acts like it isn't getting any fuel. Later discovery unveals that the sending unit is getting 6-8 Volts (is this right?) and the fuel pump isn't whinning to charge the line. So I suspected the fuel pump and now have a replacement. Do any of ya'll have any tips for this problem either before I take the tank down (I was really thinking about cutting a hole in the floor of the cargo area lol)?

Thanks for reading, and sorry about the seemingly endless paragraph. -- Chris

You need 12 plus volts to the fuel pump

Does your battery have a full charge? Connect your voltmeter to the battery, should read close to 13 volts.

See this link & do this simple test

Connect the ground wire to the negative post on the battery & turn the ignition on. Does the pump run?

If it does'nt you need to check for voltage at the inertia switch under the dash on passenger side.

The inertia switch is fine, it hasn't been set off and I made sure it was getting what it needed. The fuel pump isn't charging the line (no hum when I turn ignition). I was using a cheap voltometer to check the connector on the sending unit (thats probably why I'm not getting 12 or so Volts). Is there a good place that ya'll know of that fixes these manual transmissions? My old truck is getting old and I dont think she's gonna make it anymore (she needs some work).
