Went to start my car this morning and it won't turn!! Just crank and crank and nothing. I've had zero problems coming up to this. Aways would start on the first try with no hesitation. Just woke up and won't start now. This is a 00 ZR2 Blazer 4x4 with around 70k in miles. I heard having to replace the distributor isn't uncommon. Any help or advise? THanks!@!

 

When you first turn the key to the RUN position, do you hear the fuel pump come on? If not, pop your hood and find the fuel pressure test port (behind the throttle body & air intake tube on the larger diameter fuel line). You should have to remove a cap, then with a screwdriver and a rag, see if you get fuel out of the test port. Then turn on the key again and see if you hear the fuel pump. Next thing to check would be the fuel pump fuse and relay. Check the fuse first, then swap the relay with say the horn relay or the wiper relay. Then hit your horn/wipers (which ever you switched it out for) to see if the relay is still good. If the relay and fuse are still ok, then move back to the tank. Being an '00, you should have the plastic tank. There should be a crecent shaped indentation on the bottom of the tank (IIRC). Hit that area with the tank with something broad enough as to not damage the tank, but still give a good shock to the tank itself. Try to start it again. If you make it all the way to this step and you are finally able to start it, you're fuel pump is on its way out and this will only buy a very small amount of time.

If you have fuel at the fuel pressure test port, then I would go to testing the fuel pressure to make sure that it is at the proper pressure (55-60psi).

Good luck and let us know what you have tried and what the results were so we can help you out further if necessary.

 

first, make sure that you have good connections on the batt. Then check for spark at a plug. if no spark, check cap and rotor. if you have spark, make sure that your fuel pump is kickin on.

 

Are you getting fuel??? Sometimes the fuel pumps will just fail. If you turn on the key and listen back by the tank can you hear what sounds like a whining or whiring noise, this would be the fuel pump pressurizing the lines. It should sound for a 2-3seconds if it is working correctly. If not then one idea on hear is to smack the bottom of the tank to see if it will free up the motor, not hard enough to dent it but enough to vibrate it and the fuel to shake up the pump...I personally don't like the idea of banging on things but if it works then you know what your problem is...

 

My intuition is that my fuel is okay. How do I check for spark? Just unplug a plug from the distributor and see if there is spark? I replaced the fuel pump last year and I can still hear the fuel pump pressuising. All fuses and relays have tested out good.

 

Well to check for spark I would go to your local auto parts store and find spark indicator tool. It plugs into the wire either between the cap and wire or at the spark plug and wire. This is better than just pulling a wire and getting the shock of your life....and hoping you see he spark before the wire moves and the spark goes away.

 

You could pull a spark plug wire off a plug, insert a phillips screwdriver into the wire and hold it so the shaft of the screwdriver is close to a ground (ie exhaust manifold), have someone crank the engine and watch for a spark.
But, 20Blazer00 has the better suggestion. If you use a spark tester, the spark travels thru a resistor and shows that the spark is actually strong enough.
Keep us up to date.

 

Okay, i went out to test for spark. All I had was a poket knife at the time so I stuck it in there and held it next to ground, and apparently the knife isn't very well insulated cause I got a pretty sweet shock. So, where does this put me? I banged on the fuel tank and nothing. Still just cranks and cranks. I know there's gas in the car. So whats next?

 

I'd change the fuel filter under the drivers seat. I did it in my 97 Chevy and it made a huge difference. You might have a clog there if you have enough spark to make your fillings in your teeth get hot. That fuel filter is pressurized, however you spell it. Be prepared to release the pressure or just go rambo and twist away, no smoking!!!

 

When you have the ignition and key on are all the likght on the cluster on? If not you got a fualt and will not turn you car on. Try replacing your coil, rotor and cap if you haven't. Good luck and keep us informed.
