Have you checked the fuel pressure? Can you hear the fuel pump when your turn the key to the on position?
Has a OBD fault scan been run?
If you have fire to the plugs, most likely it's a fuel related problem.
Good luck ...hope this helps.

If it has the vortec v-6 in it the spider injector is pretty good at going out with no warning, and if have spark at the plugs that would be where i would go.

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.

Whenever I had this problem, it was always cured with a new set of GOOD spark plug wires. Not generic set off the parts store shelf. Get some moisture removal spray and put it on both ends, the coil and the plug, before putting the wires on. Do one wire at a time so you do not get them mixed up. I do not think you have a distributor or a cap. If you do replace it also as it is over 20 years old.

Hi, Ok you have confirmed that it's not a fuel problem. You need to check for spark. Pull the coil wire off of the coil(secondary lead-looks like a spark plug wire) Have some one crank it over and listen for a popping sound. IF yes, spark is at the coil, that means all ignition sensors are working. Next check for spark at ends of wires after cap. IF no replace cap and rotor. IF yes remove a couple spark plugs and check for fouling(wet, fuel etc...) IF yes replace or clean plugs and retest for starting. IF no spark is present at coil you need to scan computer and watch for rpm signal. IF no rpm signal, replace crankshaft sensor with OEM delco part. BIGGEST problem with these engines is Cap and Rotor burn out.

1999 chevy blazer wont start turning over but not firing replace distributor cap and rotor any througts on it


first check for spark disconnect any plug wire from the spark plug remove the spark plug from the engine reattach the plug wire and set it on the fender well DO NOT TOUCH THE PLUG OR WIRE AND CRANK THE ENGINE AND SEE IF THERE IS A SPARK BETWEEN THE ELECTRODE AND ARM. if there is no spark you have an ignition problem check for 12v at distributor.
if you have spark then check fuel pressure the fuel pump could be bad.

Won't start, fuel pump runs at key on, spark at coil wire into distributor is yellow, little or no spark at plug wire ends


Sounds like bad distributor cap or rotor. If ones bad, might as well change both. Take off the cap and if there is a black color on the ends of the prongs, or on the end of the rotor, time to replace. Is it getting fuel into motor?
