I don't think 3 months makes stale gas, maybe year old gas, but not your short time. And if not mistaken, I think you have throttle body injection on an '89 chevy, although chevy always was a little behind the curve on new improvements to cars. hint, hint.
The computer has everything to do with it. it controls ignition timing, it controls spark, it controls the fuel pump and the injectors. Since it won't start with starter fluid or gas, next step is to look into the ignition system. Check for spark on a couple of spark plug wires. If you have a blue, snapping spark, you can assume your ignition system is working well enough to start the engine. Take a spare spark plug or pull one of your plugs from engine, attach the plug wire onto it, and lay the plug on a metal piece of the top of engine-the spark plug hex and threads is the natural ground for the plug, so if you lay the threads on a metal piece, or hold it tight against a steel bolt, you can observe the spark jumping the gap, and no danger of getting shocked. But if you hold it, just in case, wear a glove or wrap a heavy cloth or rag around the wire. Remember, a blue energetic spark has to be seen to verify good ignition. Oh yes, you need a helper to crank the engine over while you watch for spark. If no spark, and you have a distributor, check the coil wires output at the end that connects to center top of distributor.Pull it from distributor and hold the metal end terminal no more than 1/4 inch from a ground source, a bolt or the frame, or an engine bracket. Helper has to crank the engine over, and watch for good blue spark. If no spark there-ignition: coil, crank position sensor (or maybe a pickup coil inside your distributor-same function), ignition control module, computer, and all the associated wiring.
If coil has spark, but none at plug wire ends, inspect closely the distributor cap and rotor. not passing current or shorting out there.
So the basics are, to run, the engine needs gas, air, compression, and a timely spark.

SOURCE: engine turns over fine , car will not start.

well the first part of your question i was all ready to tell you to put a new fuel pump in, now not so sure, there is a relay for fuel pump, can you hear pump cycle and relay click? relay under hood you will have to listen close they don't run long maybe a couple secounds, if you don't relay bad. if you do pump could be bad, do fuel pressure test pump could be weak. don't think sunroof and turn signals are related, but stranger things have happend.

SOURCE: Engine will crank but will not turn over

Do this, take the top off the carb, being careful not to damage the gasket. Then take some carb cleaner and clean out the bowl and floats. Remove the needle valve and clean it out. Put it all back together and filling the bowl with carb cleaner. Start it with the starting fluid. Once you run the carb cleaner through it, it should start to run on it's own. Whatever you do don't shut it off for about 20-30 min unless you have to.

SOURCE: where do I spray the starter fluid (air intake?)

Follow the large (4") black rubber hose that runs from the air filter box to the engine. You can remove it at the engine end (attaches to the throttle body...you do not have a carburetor) I'd spray carb cleaner in there...it burns as well as gasoline and won't damage anything...starting fluid is very volatile and can. Normally, after running out of fuel, all that you'd need to do is leave the key in the run position for about a minute and you should get fuel up into the system. If it fails to start after several tries, likely something else has gone wrong and you will need some diagnosis to find our exactly what.

You say t pump is coming on, but do you fuel coming up to the fuel injector rail? You can check for fuel by pushing down the valve located at the left front side of fuel rail. It looks like a tire air fill stem. Be very careful as fuel is under 40 psi pressure and can spray all over the place. do this with engine OFF and have a rag to cover the valve. Just press with tip of screwdriver and be sure valve is covered. If a little gas come out,you know you have fuel. If not gas then check fuel delivery system i.e pump, filter, lines or pickup tube.

If there is fuel in the rail, then there is most likely a problem with the control module (computer).
Check for fault codes with an OBD II reader. You can usually rent one at your local part store. You can look up fault codes to find out where the problem might lie.

More questions, just leave in comments.

Good Luck.

My 1989 Chevy S-10 Blazer has died now three times at a traffic light. each time it has started up roght away, but the third time it would't. It had gas and the starter was trying, but it wouldn't...


No one can honestly say what is wrong. But I can tell you of a few things to check.
When it dies and won't start try to find out if its missing fuel or spark.
The first thing I would suspect is something ignition related. The ignition module can be an item that has intermitent problems. Auto Zones can test those and for free. Its located under the distributor cap. Don't forget to use a heat sink paste when installing an ignition module.

Check the connections on top of the Throttle Body. Those injector plugs sometimes break and can pop off the injector or the wires can short under the air cleaner if they have been pinched. This does not usually cause an intermitent issue but can. Listen for the fuel pump to work when you fist turn the key on.

Also if there is an alarm and it disbales the vehicle from being started that could very well be it.

My 1989 chevy s10 blazers sw runners are out, but my head lights work, and i know its not the blubs.


Try checking the fuses. There are two sets, one under the hood on the right side, and one under your steering column to your left which may be a little difficult to get to. If that's not it , you have a short in your wire leading from your sw runners not your headlights. I hope that helps.

check routing of ignition wires--especially on cylinder #6. wires too close to engine may leak sparks. May want to buy new wires if yours are old.
