I turn the car over and its just keeps on turning over there's gas going thru the lines and I replaced the spark plug and wires to make sure they weren't the problem but it still does not start. It starts on certain days when it wants to start. But when I shut it off after I'm done driving it for an hour It'll not start for days sometimes longer. What's the deal?

Re: 1998 ford explorer wont start
What does anti-theft light do when this happens with the key in the on position.Does it come on for a sec then turn off or does it flash rapidly? If it is flashing then anti-theft is not seeing your key for some reason.This could be a bad key or a transponder for the anti-theft.
Second thing it could be is maybe computer isn't seeing the crankshaft position sensor. When you first turn on the ignition your check engine light should come on.It should go out while cranking but if vehicle doesn't start after a few seconds of cranking,while the engine is cranking it should come back on. If it does then computer sees the crankshaft position sensor.If it does not come on while cranking then it does not see it and it will not start.If this is the case you can try and wiggle the wires to the sensor(it will be located next to the front crankshaft pulley and it reads the teeth on the back of the crankshaft pulley.

Gas, air, spark. Keep it simple. Is it spark? Could be bad gas. Put some gas from the fuel line to make sure it's clean. I recommend Getting some carb cleaner and spray it in the line and see what it does.
Check for spark. Take a plug wire off a spark plug leaving the other end still attached to coil pack/distributer. Stick a screwdriver in the end. Holding the handle of the screwdriver keep the metal part a couple Millimetres off a section of metal while you get some one to turn it over. If it is really sunny it will be hard to see the spark. Do this one plug at at time so you don't get the wires mixed up.
replace your fuel filter, and air filter ! you mean your fuel pump turns on , correct ? how do you know this for sure ? check all fuses, and especially GROUNDS ! ground wires get overlooked , and they should'nt . without them, you got nothing !!! tune-up lately ? replace spark plugs & wires ! distributor cap & rotor . oil change lately ? do it ! spark plug wires get old, hard, and crack, causing them to short out ! check all vacuum lines, if you have a throttlebody, tighten the mounting bolts, they do get loose !
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.
First make sure your actually getting spark. Remove a plug wire and install a plug in it and ground it. Crank the engine over and look for spark. Next make sure your fuel pump is working the way it should. Turn the key to on and check and make sure you hear the fuel pump buzz for a couple seconds and shut off. If there is no spark then the ignition module mounted on the side of the distributor will need to be replaced. No fuel then you will have to replace the fuel pump.
change old oil and filter make sure all spark plug wires are there and look ok take spark plug out and pour little amounts of marvel mystery oil down into cyl. then turn engine over acouple times if it has a oil pressure guage make sure with spark plugs out and engine turning that you have some oil pressure.then take some fuel line and connect it to the fuel pump on the side of the engine you most take off line going to the fuel tank in order to do this then put all but one spark plug back in the put all the wires on then the one plug that you left out check for spark by installing the wire on the plug and setting the plug on something metal on the car (grounded) the turn the engine over and look if the plug is making a spark if so put it all back together. then with that line you put on the fuel pump stick it into a gas can with plenty of fuel then pour a tiny amont into the carb and try to start
