It will turn over but will not fire off. Lastnite it started fine and around lunch time it just will not start. This problem happened about a month ago and I checked the the line to see if the fuel pump was pushing air and fuel out and it was doing that perfect! So I just replaced the fuel filter and it started right up. Didnt have a problem for while until today. Check engine light is not coming on.

Well just to clarify there shouln't be any air in your fuel lines it should only be pushing fuel, air will show as bubbles and this is a problem. With the mileage you have on the vehicle a full tune up is due and any of the things in a tune up can cause your problems. I would recheck that the fuel pump is pushing plenty of fuel up to the motor, check the spark plugs, MAP or MAF sensors can cause hard starting. A bad starter could be the problem. As always get the codes checked if possible.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
