I've posted before, no cash for a fuel pump atm but I wanna get this SA going.

The batt was reversed I got everything working but no fuel pump sound, would the fuel pump its self die or the wires if it was reversed?

Its a 79SA so maybe the wires burnt out?

If theres any hope I suppose we could move the car to get to the fuel pump, any body know where it is on a 79SA, right rear wheel area right?

 

I'm not sure how your 7 is wired compared to my 84SE, but one time I accidentally crossed the cables, and I fried one of the fusible links. I can't remember which one got toasted.

Um, yes it can. Thats why you need to fuse everything!

 

Reversed polarity can fry a lot of stuff, not just wires. Most electronics are polarity-sensitive. When you're lucky, fuses blow to protect them, but fuses are sometimes not fast enough.

 

Well I already know theres no fuel pump working.

I don't think the fuel pump has any sort of control since its carb. My friend said the fuel pump's dc motor wouldnt be affected by reverse polarity.

Everything on the car works, the fusible links are "okay" looking.

 

Fuel pump on a 79 runs whenever ignition is on, just like my 80. Outside of the electronic ignition, 79's and 80's are real similar on wiring.

Next step would probably be to disconnect the fuel pump electrical connector & jumper it straight to the battery, & see if it runs.

If it runs, it's wiring, fuses, fuse link, or ignition switch.

If it doesnt run, it's the pump.

Remember to be careful about making electrical sparks near fuel vapor; Safe approach would be to leave the pump installed, and just use some long wire to jumper to the connector (under the sheetmetal behind the driver's seat, as I recall) for the test.

 

I'll give it a try, doing the brakes atm.

 

Okay

Where exactly is the fuel pump?

i dont wanna be up there feeling around, theres tons of black widow spiders :X already got bitten doing the brakes

 

Click the link in my signature for the FSM. The 80 one should be close enough. The wiring diagrams also show locations of connectors so you could use that to find the fuel pump connector location and then find the fuel pump.

As for the spiders, why not spray them down with poison?

 

Dont got any poison and they hide in places.

I looked at your 80fsm.

I see a similar fuel pump cover thingy.

Which bolts gets it off? 2 of them are like welded in

 

Don't even bother getting the fuel pump off yet. Just remove the driver side storage compartment behind the seat, pull up the carpeting and there is the connection for the fuel pump. Just put power to it and see if your fuel pump works. If it doesn't that your job is easy and replace the sucker. If it does work that you have an electrical problem to trace.
