Walbro in, but fuel gauge dead - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I just got my walbro installed and it's working great, but at some point I messed something up because my fuel gauge is not working. I openned it back up and everything seems in place and the connectors seem fine. Anyone else had this problem?

mRclARK1 · 04-14-2007, 01:23 PM

Mine did the same thing... it didn't read at all for about 2-3 weeks. But then the first time I filled my car right up, it started working perfectly again. Maybe give that a try and see what happens? lol

trey21096 · 04-14-2007, 01:59 PM

lol@how easy a fix that is, I thought I'd seriously broke something. Thanks man.

johngriff · 04-14-2007, 02:07 PM

so you fixed it?

trey21096 · 04-14-2007, 02:10 PM

No, but when I think about it, it makes since.
I'm going to empty it out a little more. It was full when I did the swap (never a good idea, I wouldn't recomend it.) But my old one died so I had no choice. I'm going to take it out tonight and give it a workout, then fill it up. It should be fine.

johngriff · 04-14-2007, 03:14 PM

If you bent the arm, side to side, the contact might be off, or bent in and cracked the pickup on the sensor, or you trashed the wiring...

trey21096 · 04-14-2007, 10:11 PM

I didn't know the arm touched anything other than the mounting bracket, are you talking about an S13 setup, mines S14.

youngmanvr4 · 04-14-2007, 10:22 PM

Connections maybe? On s13's they have a float arm for fuel level. S14's use just long plastic float separate from where the fuel gauge mounts.

mRclARK1 · 04-14-2007, 11:55 PM

Yeah, you may actually need to fix something. lol.. I was just saying it's worth a try, since that's exactly what happend to me. But my car is an S13, not an S14, like youngmanvr4 said; the gauges are a different design.

opticfilms · 04-15-2007, 01:10 AM

change the sending unit because some times the plastic brakes and the float dose not go up

trey21096 · 04-15-2007, 06:02 AM

I'm going to run it down and refill it first, if that doesn't fix it, I'll open it back up and have a look. The float it'self seemed to be fine. All I can think is that I might have messed up some wires. Thanks for the help.

sblack13 · 04-15-2007, 12:16 PM

had the same problem, fixed it by taking it back out. Turns out the arm wasn't sitting where it should.

youngmanvr4 · 04-15-2007, 05:19 PM

When I traded my s13 for my s14 the fuel gauge never worked. I did tests and replace the fuel gauge in the cluster, did test and replaced the whole sending unit/float and nothing would fix it. Checked the connections, they were ok. So the last thing it could be was somewhere in the wiring something was messed up. I was just going to rewire it by running a wire from the back of the cluster back the the wire in the fuel tank but before I did I needed to unwind some of the black tape right where the wires come out of the fuel tank. As I was doing this I pulled the wire for the fuel gauge and a end pulled out. So I unwound it somemore and found some butt connectors. At one time all of those wires coming out of the tank were cut and then put back together using butt connectors but they didn't get the one for the fuel gauge clamped down enough and it came out.
Thats just my experience and I'm 99% sure thats not your problem...but just try different things and see what happens. Since you were just back there something probably got bumped or pulled out or something.
A good place for help is EL pages 74-78 on your s14 FSM. If you dont have a FSM get one and look there. Alot of good help on that.

trey21096 · 04-16-2007, 07:49 PM

it's fixed, turns out the whole assembly somehow managed to get submerged. How I pulled that off I have no clue. Also, it's not part of the problem, but I had the pump sock on the wrong direction. I'm a noob, I admit it. lol

gotta240 · 04-16-2007, 11:14 PM

lol. Just make sure you "hook" the assembly were it belongs... It should be fairly sturdy once on correctly.

trey21096 · 04-17-2007, 12:13 AM

Yeah, it took me hte better part of 15mins of feeling to find the hook, but the pump assembly was on it's bracket, it was the float assembly that was completely submerged.
