There are a lot of reasons why an engine might not start.

Basic first step diagnostics: Check for spark, check for gas then figure out (usually by tracing backwards) why you are not getting it (spark/gas).

1. Does it have gas? (Check the gauge, listen for the fuel pump etc. check the fuel pump fuse.)

2. Is the engine mechanically sound? (Check compression, open the oil cap or remove the distributor cap and see if the camshaft is going up and down etc.)

3. Check the engine service light. If it is on find out what the computer thinks is wrong and fix it.

4. Check to see if the ignition system is working. BTW don't just pull a spark plug wire. This can wreck the electronics. I would pull a spark plug and make sure it is properly grounded before checking for spark.

Since your car isn't a real common one, I would buy the Haynes manual for it even if you don't use it as it has most everything that a professional mechanic would need to service it.
Haynes Storm Manual
Shop it before you buy, you may find one on eBay at less than the list price.
You should pull any spark plug lead and position it near a ground point (on the engine) and have someone turn the key as if to start and watch for a fat blue spark from the lead to ground. If you don't have any at all and your car still has a distributor, you may have a failed pulse pickup in it. If I had no spark, this is where I'd check first.

I would preform diagnostic for your cranks/no start condition which would include checking for ignition spark and fuel pressure.Once these are verified,then on to electronic controls like injector operation that can be done with a test light, ohm/volt meter or actually watching spray from the injector while cranking.A scanner that will interface your control unit might prove usefull in order to view parameters of all outboard inputs and outputs and trouble codes that may be present. This car needs air,fuel and spark to run obviously.

Why did engine running, won't restart.


lots and lots of reasons, guessing. over 50 (bad engine?)
but does it crank?, no car starts unless it's cranked or
like my car, push started or gravity started (a 6sp m/t)
if engine fails to start , and cranks robustly (fast starter motor)
then
1: never tuned up, running 10 year old spark parts.
2: blow fuse. check fuses.
3:; lost spark, check spark.
4: flooding or loss of fueling. to unflood any engine, crank at wideopen throttle (oper, guide tells you that)
5: timing belt not changed at 60,000 miles it will fail, and will not start
or start have like 1/4 power.
6: lost compression in or more cylinders.?

or
get it serviced? if all that is too much work? or confusing.

93 Geo Storm standard Transmission 1.6 Engine Lately I have to push start it Replaced ignition switch Checked all the fuses Starters good Help 48 disabled female


bad fuel, is it old? fuel.
needs tuneup, air cleaner and spark plugs , at least.
if the starter cranks fast and dont' start,
but does push started. that means the spark is weak
when cranking, and marginal spark plugs can do that.
this car is really (under Geo snake skins) a
an Isuzu Impulse
and Isuzu is defunct there too. (double bad)

now my real guess......analysis...
im not sure your order stated.
the engine would not crank over with a key before the new switch or after?
and "starters good", does that mean , it still fails to crank start with key
but the hot wiring of starter does?
try this:
tell use what happens when you turn the key, is best.
I turn the key, and i get the dash board to light up,
lots of lights. and the CEL LaMP GLOWS.
the CEL lamp, means the ENGINE brain is alive.
then you turn the key to cranks (start) position.
  1. nothing happens.
  2. it only clicks
  3. it cranks slowly,
  4. it cranks fast, just like a new car does. fast. cranking.

1,2,3,4.?

and does jumper cable starts work>?
if this works , your battery is low. , discharged or dead, or bad.
if the battery keeps going low, its bad, or the alternator fails to charge the battery, or you have phantom drains , discharging it as you sleep.

my guess, (based on most common)
is #3, slow cranks, and spark plugs are long since gone.(fouled and gaps no longer in spec>)

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)

btw2
1.6L DOHC (Storm) Interference
both DOHC engins are interfernance
if you skip belt changes, the valve bend and bye-bye engine.
BOOM

1991 geo storm gsi,Was going down the road fine and all of a sudden It cut off and cannot restart it what could be the possible problem or cuses.


same answer for all cars made 1920 to now.
never restarted ,ever ? gee , a little hint...?
1: lost engine compression hot, (gee forgot to do the 60k serviice/)
2: lost spark , yes, check spark at all 4 cyl. if bad check coil spark.
3: lost fuel or too much fuel called flooding.

one removes a spark plug, it drips of fuel , say all 4.
flooding.
crank motor at WOT, wide open throttle to clear flooding.
if the spark is good and the spark tips are dry, then try test fuel
if car starts and dies. then you lost injection.

easy huh> with the above you know exactly why it fails.
compression bad
spark
fueling.

1991 i think is TBI single injection engine, i can look it up but
no i wont. we need to do the tests first to get there.
