My little quote on the end of my signature says it all and this is why: Our reliable 95 Olds daily driver just one day for no reason refused to start. Cranking didnt work. Shooting starting fluid into the throttle body didnt show any difference, so I didnt think fuel pump. Right before I was ready to give it to the mechanic (I dont do modern cars with sensors/computers) I put the pedal all the way down and I cranked it again to see it start right up! Not wanting to claim the car just "healed" itself, I pulled a wire of off a spark plug while it was running with a pliers. Good spark as can be realized when even though I was carefull, I shocked the SH** out of myself. However, when I pulled the wire, a bunch of rusty powder went everywhere. The connection between wire and plug was all corroded. I performed a tune up (plugs and wires). All six plugs looked like they had some kind of prehistoric limestone all over the the electrodes (where the spark happens), and the electrodes were worn badly. The guy I bought it from told me all was changed previous to my buying it. Yeah, I'm sure they were changed, 10 yrs ago!!
Electricity is a smart thing. If there is a way for it to flow, it will find it. Sometimes, the resistance to it caused by rust or worn electrodes making the gap too wide for the spark to jump, will make it absolutely cease to flow. Sometimes. Then you go to try to start the car again because SOMETHING changed allowing the electricity to flow again, whatever it is.
Air, fuel, and spark are the basics with an engine. Start there with the basics. Anyone can do it. Get a manual at your local parts store and it will run you right through how to check all that under general maintanance. Air filter, fuel filter, and spark plugs/wires are your very starting point. After that, fuel pressure. If the car doesnt start and spraying starting fluid into the engine through the throttle body makes it run a bit, your fuel pump isn't doing its job. A naughty fuel pump can work intermittently doing good one minute and doing nothing the next. After that, all those variables that I lovingly call the "rocket science". Good luck.

No matter how complicated something is or seems, always start with the simple basics then work your way to the rocket science !!!
