01 L100 Fuel pump trouble

[444matt]

Looking for some guidance with my 2001 L100 4cyl Automatic 135,000 miles

The last 40k miles the car would die if the fuel level got below half a tank. Add fuel and it would fire right up, so I just never let it get that low. My grandfather was previous owner who A) would never let it get past 3/4 tank before filling up and B) had it sit in storage for 18 months prior to me getting it a year ago.

I think the pump has finally died. Last weekend with a full tank it hesitated on me several times and died once, I was able to restart without adding fuel. Drive home and parked it on level ground where it sat for two days. Now at 3/4 tank it will not start, engine cranks but seems no fuel. Can someone point me to the trouble shooting steps for the fuel system. IIRC There is a fuse and a relay to be checked before dropping tank to check the actual pump. Also after a quick check at my local part stores the price on a replacement pump seems way high. Around $300. Any help on where to find a cheaper yet quality replacement pump would be great.
