No spark at plugs . Engine won't start, check fuel first, getting plenty. Then check for spark, no spark.

check firing order of plug wires,backwards??

check see if you getting spark if not.have vechicle code scan could have faulty ECM .faulty camshaft sensor and crankshaft sensor.make sure engine has been tuned up.replace fuel filter change spark plugs and wires. before engine can run need fuel and spark.either one not working car will not crank.

Technically if the engine has compression, is getting spark at the right time and fuel, it should start.
Have you checked the spark plugs to see if they are fuel or oil fouled ?
Are you getting spark at the plugs or at the coil ?
Have you tried using carb cleaner or starting fluid in the throttle body ??
Have you checked fuel pressure to see if you are getting enough fuel to the injectors ?

If you have spark at the right time, compression, and fuel, you should have combustion.
Was it running before you had the work done ?
Is it possible the distributor timing is off ?
You know for sure the plugs are firing, not just the coil ? And the accel pump in the carb is spraying gas ? And the choke is closed ?
A major vac leak like the PCV valve hose or intake gasket could keep it from starting.

CHECK COIL PACK OR FUEL PUMP

If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.

Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.

The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.

Possible bad coil pack, since the plugs are not firing work you way back to the coil pack which is the 50k-70k volttage box that send the sparks through your wires to your plugs.

a combustion engine needs 3 thing`s to run 1st air (check air flow) 2nd fuel (check fuel system make sure it is getting gas to engine) 3rd fire (make sure your getting spark to your spark plug`s)

Check the distributor and timing order to make sure it has not jumped at all from a timing malfunction.

The engine needs three things to run, fuel, air and a spark at the right moment. Check the static timing of the motor, if those marks line up. You did not say you were getting any spark at the plugs. If you have spark, then try a little starting fuild into the intake while turning it over. If you have fuel delivery to the cylinders, the spark is coming at the right moment then it should be running. Any error codes set?
