Three in the front under the engine cover, then under the coil packs, there are three more in the rear of the engine at which you must properly remove the intaker manifold and do this by procedure or risk warping the head and manifold. If you must ask, I highly suggest taking this to a pro. Sorry
What engine do you have?
I have a 2002 Escape with 3.0 V6. It sounds like the ignition is getting damp and the engine is misfiring. If the CEL is flashing, you really shouldn't be driving it. Check the owners manual, but you could damage the engine.
Anyway, go to an Autozone or other parts store. Many will scan your engine for the DTC code for free. This code will give you a clue.
My code was for a for a cylinder misfire. I was close to 100,000 miles, so I replaced the plugs first, then the one coil. It was the coil.
Change the filter with each oil change. Unless your towing, the tranny filter is usually 60k miles. Check your manual to be sure. Your manual should spell out when maintenance is to be done. If a garage wants you to do some outrageous expensive maintenance, have another garage look at it.
I have a 2002 Escape V6 w/ 100,000 miles and I just changed the plugs. If you have a V6, you will have to remove the Upper Intake manifold. It's not too bad. You'll new a gasket set from Autozone or NAPA for about $10
Honestly it's probably just dirty spark plugs. Did you pull any of the spark plugs and inspect the tips for build up? A couple things to remember:
1.) If the timing chain broke, the valves wouldn't be opening so you wouldn't have any air coming out of the exhaust during crank. You said it smells like you're getting fuel, so I'm assuming that means you're smelling the exhaust fumes, right?
2.) The crank sensor tells the ignition system when to send a spark to the plugs. If you're getting good spark, it's unlikely that the crank sensor is faulty.
If it's too soon for spark plugs to need replacing, check your sensors. A faulty oxygen sensor for example could cause your engine to run 'rich', resulting in faster crud build up on spark plug tips.
