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.

    not only is it belolw the ECU (behind left speaker) but has green socket, and a large pink wire , pink is FUEL PUMP power. but , IGcoil and FI fuses must be good. for the fuel relay to energize, and only does so for 3 seconds, keyon , and can be heard.

    but the pages above are clear, and full FSM book facts, and real photos, of all years, 89-98, no need to guess, just look there, and the logic that makes it work is there too, why people guess , amazes me. one other fact ,hot wiring the fuel pump relay is a 1:4 chance to blow up a $400 ECU.

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).

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.

SOURCE: We can't get our 1991 GEO Tracker to start

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.

You should have two sources of power, a ground from the computer, and the circuit going to the pump.
Do you have both sources of power when the key switch is turned to start ?

Where is the fuel pump fuel located on a 1990 chevy geo tracker


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

http://www.fixkick.com/INJECTORS/89/89-90schem1.jpg

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.

New fuel pump not pumping fuel 91geo metro


Check your fuel pressure regulator. Pull out one of the fuel injectors and put it up to a towel, have someone crank the car and see if it sprays fuel. If theres no fuel being sprayed then you know there's something else wrong along those lines.

1994 geo metro . fuel pump relay is fine but there dose not seem to be any gas coming threw to the throttle body ..should i be able to hear the fuel pump prime for the fact that i cant..


If there is B+ getting to the relay then B+ should be making it to the pump if the relay is a-ok like you say. If B+ is making it to the pump and the pump is not buzzing you need a new pump. If B+ is not making it to pump then you need a new relay providing that B+ is making it to the relay. If B+ is not making it to the relay then its likely that the ignition switch or whatever supplies the pump relay with B+ is at fault.

Not getting fuel blows out fuelpump relay


You have either a shorted wire going to the fuel pump or a bad fuel pump. I'd guess you have a bad pump, wires enter at the top of the tank anyway, so probably water condensation has rusted the pump.

Have the computer checked. My Dads Tracker was doing the exact same thing and it turned out the computer was bad. I'm afraid it wasn't cheap to get the computer refurbished either. ($500)
