Replaced coil, wires, cap + button... still no start Coil is getting power, Fuel pump works.. Engine is turning over, but it sounds like its skipping a beat[?] if that makes sense?, Like a doo-doo-doo-doo-duh-doo-doo-doo-doo-duhh... Please help!
Here is how I found to cope with this until a permanent solution will be found. Before starting , you switch the shift to "D" (drive) and turn the ignition key to start. Obviously , the car won't start, but what it does it builds up pressure somewhere . You can hear from outside that something is putting some air pressure. Then switch the shift back to "P" park and try to start along with pushing the gas pedal as you start

Re: Engine turning over but no start...
Is it getting spark? remove one spark plug wire and put a spark plug in it, hold the body of the plug against an unpainted metal part of the engine or body with an insulated tool (like a plastic handled screwdriver) and get someone to wind the engine over. You should see spark at the plug. If not, check to see if the igniter module is switching the coil correctly (might want to search on the net for this procedure, too hard to explain here). Probly best to just replace the igniter module anyway with the age of the vehicle.

Without a voltmeter and a wiring diagram, you're in a bit of a fix. But I would be wondering why the ignition switch isn't sending power to the coil primary positive terminal, and why it isn't causing the fuel pump to be turned on, too.
Is your check engine light on with key on? The computer should sense ignition is on and briefly turn on the fuel pump through the fuel pump relay, on just long enough to pressurize the fuel line to the injector. But no fuel or fire-you'd better start by checking if the ignition switch has power in and power out, and work your way to the coil.
Sounds like you replaced alot of parts for nothing. The pickup coil in the distributor "fires" the module which grounds the coil and the injectors. Those components would need to be tested. The coil fires the plugs when the ground is removed by the module or the key switch.
REPLACE DISTRIBUTOR CAP AND ROTOR.AND PLUGS WIRES.IF GETTING NO SPARK TO PLUGS.CHECK SEE IF IGNITION COIL GETTING POWER.IF NOT CHECK IGNITION FUSE.IF POWER GOING TO COIL.FAULT EITHER COIL IS OPEN OR FAULT IN THE IGNITION MODULE IN THE DISTRIBUTOR.
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.
Check ECM for water--unhook connector, dry as necessary. ECM is driver side, front side of wheelwell, mounted on inner fender. Your ECM powers injectors and coil. Might want to check ignition fues in battery fuse box too.
the easiest and fastest way is to listen for pump activation when you turn you key to the on posistion turn your radio off turn the key to on (just before the point of starting)and you should be able to hear the humming or vibrating if you dont then you are not getting fuel. if the pump is working or you cant tell if it is go to the fuel rail look foe a cap that looks like a valve stem cap take this cap off and push the stem in if you get fuel then you know that you donthave a fuel problem if you dont get fuel to the rail then its probably the pump. hope this helps you.
Replace the distributor,it has all the components in it,that would go out,But check the fuel pump pressure first,to see if the fuel pump is even working,then see if the rotor button is turning.Pull the distributor cap off,and turn the engine over,see if the rotor is turning,if it is not,then the timing belt has broke.
i got a 1994 f150 that starts but cuts right back off so i had no fuel psi so i put a new fuel pump and fillter then found out that it was not getting power to the pump the cut off is not triped and no brakes in the wires can anyone help??
