Changed the head on 91 geo storm 1.6 dohc the timing is right it sounds like it wants to fire but it won't all it does is crank over

I believe this is for 1.8L engine, serpentine belt. If you have a different belt for each component, that is a different issue? With multiple belts, the component usually has a pivot bolt, you loosen the bolt, then move the component to release or increase tension on the belt, then tighten the bolt.
With a serpentine belt, the tensioner does that for you.

ck timeing belt may have jumped

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?

which engine is it.
open hood, see that EPA sticker it tells you which there.
interchange
short block
long block
or long + manifolds and all sensor.
what engine.?????????

• 1.6 L SOHC 4XE1 I4
• 1.6 L DOHC 4XE1 I4
• 1.8 L DOHC 4XF1 I4

pickone.

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

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 .

storm is an ISUZU
and had 3engines,which one? below is off wiki on storm.
1.6 L SOHC 4XE1 I4
1.6 L DOHC 4XE1 I4
1.8 L DOHC 4XF1 I4


coil makes 50,000 volts (even 1kv makes fire, but is too weak spark
spark plugs dead , right? all 4 right?
ever do a 60k mile tune up ? if not why not, it gets new spark parts then..
also, if the cam timing is off. the dizzy sparks between towers
make the distributor useless, it cant distribute spark.
so the first tests are .
static ignition timing. (yes, a tool, called a timing light for $20)
if timing is good the the wires HV are bad.
if timing is bad, bingo..... this is the first test on any motor.
if the timing belt or chain on any SOHC or DOHC engine slips
the dizzy will be way to h3ll off.
learn to use a timing light, and works 100% cranking.

look at that distributor cap (replace it)
see the coil wire , center, that is at 50kv spark.
and see that rotor, if the spark is good at the cap pins 1 to 4
then the dizzy is timed.
if the spark dont reach the spark plugs that means
the wire are bad or the spark plugs are shorted, or both.
its that simple. using a real spark testing tools tells you the KV.
kv = kilovolts. the best tools $5 bucks have and adjustable gap
this car is not 100kv, like newer cars and must be set (tool) to 50kv or tad less to show full powerful spark.

take care not to get shocked, keep hands off the parts
as friend cranks (or remote start button tool)

Double check crankshaft timing mark, on your lower timing cover has some timing marks - crankshaft should be on the 0 mark. Camshaft timing marks--intake camshaft mark set at 3 o'clock and exhaust camshaft mark set a 9 o'clock. These timing marks are critical for motor to run and start correctly. These timings marks can move while trying to install the timing belt. After, you confirm or reset timing and belt, you can confirm timing is correct by rotating the crankshaft twice. Your timing marks should be on right on timing marks discussed at the top of the page. If timing marks are off, start over with timing process.

Firing order - 1 - 3 - 4 - 2

Cylinder # 1 is to the left when viewing the engine from the front of the car. They are, left to right, 1 - 2 - 3 - 4.

Looking from the side of the distributor... starting from the top right counter clockwise it's 1 - 3 - 4 - 2
