You can bring it to AutoZone or Advanced Auto Parts or similar auto parts store and they will check the codes for free. Otherwise you'll need to bring it to a mechanic, and they're going to charge you to read the code. They will also know where the port is on your vehicle.

Unfortunately, there's no way to read the codes yourself from home unless you have specialized equipment, which will cost more to acquire than if you just brought it to a mechanic to read.


I hope this is helpful

What will cause a 1990 geo storm sohc to run rough or not start? Changed, plugs, wires,cap, rotor?


Except for the ignition coil, that about takes care of the secondary ignition system. You should check to see if you have a good strong blue spark at one of the spark plug wires. If no spark, check the coil and the crank position sensor for one place to start, also the ignition control module. If you do have spark, the ignition should be good, and then you could concentrate elsewhere.
If there is a schrader valve on top of the engine-a fuel pressure test port-it would be easy to check fuel pressure. Autozone and others loan a fuel pressure tester. Possibly, a 1990 Storm may require a temporary "tee fitting" in the fuel line somewhere to test pressure. Look for the test port- it may have a cap that unscrews. It would be located in the fuel rail or the line to the injectors.

Beyond that, other problems could be dirty injectors, a malfunctioning EGR valve, a large intake manifold gasket leak, or worst case, a mechanical internal problem. If it gets to that, perform a compression test. If you have good compression in all cylinders, it should be good internally.

Timing marks on 1.6 dual over head cam


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.....

1st google hit
http://www.robietherobot.com/storm/torquespecs.htm

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 .

1990 Chevrolet Lumina Base 6 Cyl 3.1L (88,000 miles) June 3, New spark Plugs installed. (Original Spark Plug wires remain) July 15, Power Brake Booster Replaced. Shop said battery was disconnected...


recommend getting a scan of the OBD II connector for trouble codes, then get back to us. Autozone and Advance have free scanning service. The trouble codes will help us diagnose the specific misfire. With the codes, I can provide you some recommended troubleshooting or repair steps.

No spark from coil


Have the engine trouble codes read by a shop--that should point to the general or specific area for repair.

Sounds as if the head gasket is leaking compression pressures into the cooling system. It seems that this problem has just occurred recently. This can be checked at your rad shop. They have a tool that uses a chemical solution that changes color if there is any engine gases present in the coolant.
