Running problem plugs and leads

Fuel Pump - can you here the pump (usually under the right hand back seat) running with ignition on?
Fuel Delivery (injectors) - squirt some fuel (just a cap full) into the manifold.
Spark - pull a lead off a spark plug and use a spare spark plug resting on the exhaust manifold.
Crank sensor - Injectors won't inject fuel if the ECU thinks the engine isn't turning. Crank sensor is at the front right lower side and as it gets older, the wire gets brittle and breaks most of the time where it meets the hard end. The connector is under the throttle body and should read 500-600 ohms.

check your coil. follow your spark plug wires and it will lead you right to the problem.

Never rule out sensors, based on the fact they sometimes
work or you have spark

You need an oscilloscope and look for milli second
misses and spikes

Use the scope on everything,fuel pump etc

Maybe something as simple as a fouled plug. Have you checked spark plugs? Wires? It's a process of elimination...

check to see if your plugs need changing and then check your HT/LT leads on the plugs as they may be loose or water clogged somewhere or have a split wire that is just touching enabling it to fire a few times

remove the top covering the intake manifold, thr spark plugs and coils are located in what appears to be the valve covers under the black plate

Try checking the spark plug, and the spark wires, if that doesnt clear things up then try replacing the roter under the distributor cap and check the cap for any corrosen

are the plugs firing in the right order?

Install hotter plugs and run it harder between stops. Also check your fuel pressure regulator.

check spark plug gaps are set correctly and that leads are in correct order if you took all leads off at same time its easy to mess up just one or two
