fuel cell wireing

hey man I am haveing the same problem but mine is a s-10 I got fuel pump to work but I dont know what wires run the sending unit so if you figure that out let me know I will look and see what wires are the pump

ok i got the pump working last weekend... not a big problem but now i just need to wire the sending unit.... also the truck runs like shit now... it spits and sputters... any ideas.... just curious... if any one else has had this problem

recently ive done 2 cells so lets see if my memory serves correctly.

there should be 2 plugs on the top of the OE sending unit/pump plate. one is not used, it has to do with vapor stuff.

the one used has 4 wires. (this is from memeory know) the wires are grey, green, black and purple. the green and purple go to the sending unit. hook one to each side of the new unit, if it doesnt read correctly reverse the wires. the black is a ground, and the grey is power to the pump. (PLEASE DOUBLE CHECK WITH A TEST LIGHT OR METER)

on both ive used that exact pump and havent had any issues with sputtering or anything, and one was a v-6. make sure no lines are crimped or anything. good luck

thanks...... whats the orage wires for.... i read that pressure sensor.... that sounds important... what can i hook that too... any ideas...

hey man, did you try reversing the wires? it may be an issue of sending unit ohmage and gauge ohmage not being correct. both ive done i havent hooked up the sending unit, so i couldnt tell you first hand. sorry bro

yeah tryed that same reading for each wire....

You got the wrong sender.

wes get this thing done and out of my shop jk well it looks like we need to call summit and get the right sender for it
