On a 1991 geo tracker trying to find location of fuel pump relay

the 91 is below the ECU, the socket is green , the relay has a huge
pink wire, which is pump power.
did you find the bad ground in 2door car? is it? behind the left rear tail
light, the pump grounds with a screw there, all trackers (sidekicks) fail there. , and kill the pump, it the first check on all . with low or zero pressure.
post symptoms and can take you to it fast.
just a no start ?
this year, kick has pump power for only 3 seconds keyon
that be rule 1.
and pump power 12vdc cranking and running.
the wire is pink at the left tail light too.

every pump that ever failed, in every way possible, is here.
read this.

2door or 4 door is first quesiton.

here is my 91
and my FP relay

old post. tracker day.
there IS NO dedicated fuel pump fuse. like 1991 to present
but uses the same fuse as ECU and SPARK
IG-COIL

the orig book by suzuki (eek, GEOs) has an error
and is corrected only on this page.
in red.
btw the car does NOT run the pump key on, until 1991+.
so, you must crank it and check pump voltage !!!
same as 1996 J18 sport engine. (tricky rules no? and i know them)

that relay will break the bank, so learn to tests first.
and how. ask. can do. done many, of these.

hi u could have ablocked fuel filter try replacing it if u have and motor is carburetered check were fuel line fits onto carby theres often a fine gause filter inside the bango fitting hope this helps

I had this problem as well. The tracker had sat for 8 years and would only run off of starter fluid. I replaced the filter and fuel pump then I had no fire. Located under driver side dash in the fuse panel theres a fuse for coil. I don't remember which one, but, I am pretty sure it is a 10 amp fuse. Or just do like I did and replace any bad fuses. If that doesn't work it will be a relay located above that same fuse box.

This could be as simple as a fuel pump. Check you fuel filter and then replace the pump.

check under the back sit

probably becuase its faulty...try replacing it and go from there...or else there is another source of resistance in the circuit some where....also, check your fuses....a blown fuse will stop flow of current as well.

check fuel psi at fuel rail with fuel tester, if u think its a fuel problem.
prob a spark prob. check spark with spark tester.

how old are the spark plugs?

The fuel pump relays are mounted on an "L" bracket underneath the ECM. Both have something to do with the Fuel pump. Be careful not to get it confused with the horn relay it is in the same vicinity (under the dash on the drivers side).
