I have a 1998 Ford F150 v6 and was running good until all of a sudden one afternoon it cranked but didnt turn on. I checked all the basics like battery, fuel intake, fuel filter, spark on plugs and so far good. I even sprayed starter fluid in to the intake and no luck. It will start if I floor the gas peddle but hakes and intake pops as if the timing were bad or something. Could it be a sensor of some kind.
Start with compression test, fuel pressure test and spark. Something is not working correctly.

Timing prob, to low. To much fuel, fuel pressure reg. Spark plugs need replacing. Pull a plug or to, if they look real bad and smell like gas, put a set in then see how it does.
If that helps for a bit and gets bad again it is getting to much fuel.
