Hi I am having a problem for the last couple months with my Taurus. In the morning it usually starts right up. I drive it fine. If it sits for a long time (like hours), it will start up again. But if I drive it for errands or something, with a lot of start ups in a short period of time it eventually wont turn over when I want to start it again. It really sounds like it wants to but it just wont turn over. I have done the following... replaced battery, checked alternator (is fine), replaced spark plugs, replaced fuel filter. Running out of ideas. It's VERY random. If it doesnt start I usually wait an hour or more and then it just starts up like nothing was wrong. It's very annoying. Any help out there? Thank you!

If it refuses to start don't wait for nothing- do below to find out if its fuel or spark problem that's causing it not to start-something has to give.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing.
