OUR 1990 GEO STORM JUST QUIT RUNNINBG. WE HIT ON THE FUEL LINE UNDER THE CAR AND IT KICKED THE FUEL PUMP ON AND WAS ABLE TO DRIVE IT ABOUT 2 MILES BEFORE SHUTTING OFF. IT REVED VERY HIGH. IS THERE A RESET BUTTON FOR THE FUEL TANK?

Please refer to the diagram. Fuel pump relay is #15. Good luck.

storm what engine? 4xe1 or 4xf1 SOHC or DOHC (twin cam)?
its really an Isuzu Impulse in snack skins (badges)
does test fuel run engine? that is step 2.
if the cam timing belt slips, the DOHC goes boom.
the SOHC engine belt slip,cause no starts, due to huge
compression drop, and fails the test fuel tests.

SOHC, keyon, 30-46PSI
same for both. engines
but as all mPI engines it drop running at idle.
and rises at WOT> (FPR actions most work right running) ask
but its no running
ever do a 60,000 interval tuneup with a new cam belt.
no?

storms, those are very rare. and Isuzu is very dead here.USA.
which size engine?
wont crank/?
or cranks ok, but wont start.
its old.
1:check compression, yet, over 150PSI (w.o.t)
2: check for spark at all 4 cylinders?
3: try test fuel if spark is good (spray fuel)

tell us how far you get.......
btw , it really a:
manufactured by Isuzu and sold in the United States by General Motors from 1990 through 1993 as part of GM's Geo line

btw2
1.6L DOHC (Storm) Interference
both DOHC engins are interfernance
if you skip belt changes, the valve bend and bye-bye engine.
BOOM
and a new motor is more that car is worth.

the geo storm, 1.6 DOHC
the FSM cover it, so does alldata.com
hint 2, its an Isuzu engine.
its really (makes information easier to find )
Isuzu:
4XE1-UW a DOHC 16-valve engine with 130 hp (97 kW)
he DOHC engine was used in the 1990-1991 Isuzu Impulse XS, in the 1990-1991 Isuzu Stylus XS, in the 1990-1991 Geo Storm GSi, and the M100 Lotus Elan.
all that off the wiki,,
all cars rare here.....

This engine is interference type
so when timed, with a new belt
roll engine by hand, with spark plugs out.? do pistons hit valves.
yes, stop, the cam is timed wrong.
no, do a compression test on #1, if pass, do all 4. 150psi min.w.o.t.
wide open throttle
a better test, is a leak down test. x4. by hand.
these acts of kindness to the engine, saves most engines.

if the leak down fails, the timing is wrong, or the valves are already
bent..
dont use a fleabay china belt, bet a GATES belt. (they last)
setting the tension is very important to a full life .

For 1990 Geo Storm 2+2 1.6L MFI SOHC 4cyl the OBD Diagnostic Link Connector is located front seating area, passenger side, under dash, above kick panel, mounted rear of glove compartment.

Hope helps

Ignition Coil or Crank Sensor

can you hear the fuel pump when you turn the ignition key to start position??( you should hear it start then stop after few sec.) If not, this could be the fuel pump fuse,some bad contact in the wiring of the fuel pump or the worst case the computer.but if you do,unplug your main fuel line to the injector turn the switch to start position again to see if you have some fuel coming out.if not this could be the fuel filter or the fuel pressure switch! hope this will help you...lipak!..

it is on the front of the engine and yeas it has one, it is located under the camshaft drive belt cover and drive by the camshaft belt, both will need to be replaced. see picture below

Try a set of plugs and wires,if not this then you may have a plugged converter.

the fuel pump is located inside the fuel tank. drop the fuel tank and unscrew the top of the fuel pump and replace the fuel pump
