'91 Blazer won't start

I have a '91 Blazer that won't start. It cranks but it won't start up. We've checked the coils, ignition module, spark plugs, and they are all fine, it just isn't getting power to the coils and we don't know why. There's no spark coming from the distributor cap. Please Help!!

Then the problem lies in your ignition relay. even though your rotor is spining there is no current to energize the coil. when you turn the key the relay closes and allows the voltage of tha battery to flow and energize the coil.

    the relay will either be located in the power distyribution box under the hood or along the firewall/fender well area.

    the relay is a small plug black or grey in color with little metal prongs coming out of it these are in the box under the hood.

Could try the crank sensor, that is where I would start. Next would be the timing & compression.

Why chevy blazer won t start after it rains ?


Its a possibility, that you can have a bad coil pack. start the vehicle, and spray the coils with a mist of water, from a spray bottle. If bad you see a spark. The coil pack is cracked somewhere.Meaning it was not water tight. It should be. Good-Day!

Ny 1989 chevy blazer S-10 V6 2WD won't st,art,


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.

My 1994 cavalier lost spark to cylinders 1 and 4. Which components are directly related to ignition spark and timing? What about the camshaft sensor?


You listed all the components involved in spark timing and control- coil, ignition module, pcm, wires, plugs, crank sensor, and cam sensor.
Cylinders 1 and 4 have the same coil for both, so concentrate on that coil. You still have a good blue spark on cylinders 2 and 3? If you have spark there, I don't know about the cam sensor-I think it would be good if it works at all. You need to check if you have 12 volts power to the coil for 1 and 4.

1999 chev blazer won't start new fuel pump


So, do you hear the pump buzz on, when key is on? If that's good, then check your ignition circuit: check for spark at a plug. Use insulated pliers, hold end of plug wire 1/4 inch form engine bolt or ground source. When cranked, you should see a bright blue spark. Yes? Try another plug wire, too. No? Try another plug wire. If you have NO spark, could be your coil, coil pack, crank position sensor, ignition module. I would recommend using a diagnostic flow-chart to go through the ignition circuit. That way, you are not replacing unecessary parts_Expensive! Of course, if you have spark at plugs, your ignition circuit is good! Then you have to look further, like your injector circuit. Good luck.

91 camero rs starts runs 10-15mins and dies . Will not start again til cold a


Hello Ryan, start by checking the battery terminals and cables. The cables on these Camaros are known to corrode and cause intermittent starting problems. The next time it stalls & won't start, check for spark. If no spark, the ignition module, pickup coil, or ignition coil is likely the problem. This model did not have a crank sensor. If spark is present, check for fuel pressure. I hope this information is helpful.

Will not start 96 blazer


Go back to basics. Check if you have spark. From the coil and the plugs. Check if you have fuel pressure, check if you have compression on all cylinders. If you have all three action should happen.
