    Yes, check engine light is on or actually the emission control light is on, it is the engine symbol.

    My 2004 F-150 won't start at all. It'll crank all day but won't fire. Maybe I'll check for moisture in the airbox near the sensor

I will let you all know what's really going on. It is the same in most of the posts in the "2004 Ford F-150","engine dies" keyword search.
It is a manufactoring defect in the computer, or the case of the computer that is suppose to keep the circuts in that computer Completly DRY. When it don't and just the tiniest bit of moisture forms inside. on the electric circutry, the engine will either not start or it will run bad and die at stops, Whats worst is it connot be fixed. it can only be replaced'
FYI I got mine open dired it out s.ealed it back. It worked

My Jeep will cut out while driving and eventually go dead. After a bunch of restarts it will clear up. I've replaced almost all the sensors. Please help so it will stop


You need to test your alternator to see if it is properly charging your battery. Start your jeep and remove the positive connector from the battery. If your vehicle stalls you may need an new alternator. Also check the following issue that could cause you to stall, clogged fuel filter, choke not properly operating, faulty emissions system components, distributor cap damaged or wet, bad spark plug wires, leak in your vacuum system intake manifold or hoses. Also check your spark plugs for wear or improper gapping.

Poor idle


Hi
It sounds like an air fault, most likely the air mass sensor to the air box or it could be that there is a split i a vacuum pipe or air intake pipe check all round them to ensure no rips or tears on the underside of hard to see pipes.

the other thing it could be is poor spark as you said you can smell fuel one of the plugs or HT leads may be defective causing a lack of spark thus the smaell of fuel, sometimes the spark can still work but be very weak not igniting the fuel correctly, lastly some moisture may be getting in to where the spark plugs are or around the coils, HT leads etc, get some damp start and spray all over the electrics if you susoect this.

hope this helps
Regards
Dan

2.8 engine Would start when cool, but stall after


89 cierra? It should be DIS ignition so you can't have the timing too high. You said it has fuel and spark. Fuel pressure and injection pulse. Does it try to start if you spray carb cleaner into it?

Fuel Injection problems


Check spark output and fuel pressure when problem is present. This will help you narrow down the issue

Stalling


It sounds like all it needs is a good tune-up. I would check the spark plugs, spark plug wires, air filter and fuel filter.
