New set-up not working

Postby monzacoupe » Sun Jun 01, 2014 11:17 pm

I'm just getting around to hooking up my rebuilt sending unit and new Carter pump. It's out of the gas tank and ready to bench test. When I hooked power up to the sending unit, the fuel guage pegged to full even though the float is hanging down in the empty positon. When I cranked the engine over while the pump was submerged in a pail of gas with a hose going to another pail, nothing, no pumping of gas or anything. There has been no changes to the wiring/eletrical except a new coil last fall.

I no not much about wiring electrics but can follow directions pretty well, what should I be looking for. My volt meter says power is going to the wires for the sender/pump. Help please.

By the symptoms I would say you're missing a ground, but you say you've checked with a meter. It is possible you've blown the fuse, and the voltage you found with the meter is coming through the sender wire.
Wiring is pretty simple:
Blue- pump +
Tan- gauge sender
Black- ground
The "fleet"-
77 Vega Estate wagon- project(someday)will have TPI305/T-5, S-10 spindles/axles
72 Vega HB Drag Car -383/'Glide/9"(9.45@146.19)(6.01@117.28 1/8th)
76 Vega GT- 400/4spd/9" retired from active duty(rusty)
03 Silverado 2WD ex.cab (work truck/parts hauler)
04 Silverado 2WD ex.cab (retired)
06 Haulin' 20ft enclosed car transporter
93 Suburban- 350/4L60(retired)
00 Saturn SW2- wife's car
01 Saturn SC2- younger son's project
00 Saturn SL2- daughter's car
98 Saturn SW2- spare
and 3 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....

Thanks Spenser! The Beast lives!! First time around the block in a year or more! It was a disconnected ground wire. The new sender unit appears to be working and the fuel pump seems to be pumping.
Kicking it into gear now for next years Monzaque!

I used Tristarradiators. Here's a link to an old post with before and after pics. Turn around time was less than two weeks if I remember correctly, and they were great to deal with.

Can't remember exact cost but i'm sure it was less than $100.
