If you're getting spark at the spark plugs that's one of 3 things it needs to run. (fuel, air and spark)
I would suggest performing a fuel pump pressure test next, also check for fuel system contamination. ie water and/or rust in fuel.

Mechanic felt plenty of fuel also sprayed starter fuel mixture into throttle body to no avail.... Thanks

Have you tried removing a spark plug to see if they are fouled?

[Gary RVRoamer]

Back to basics... an gas engine needs air, fuel and spark to run. One of those three isn't happening. Is there fuel in the line? Can you loosen an injector to see if fuel is going to the cylinders?

Check air path to engine, filter and tubes for rodent nests, wet filter.

an engine with a working starter, in motion, with starting fluid squirted into it, must run, or pop or sputter or backfire, if it has spark.

You have no spark.

Look under your dash to the left of your steering column. You should see a single black ground wire running from the wiring loom to the left side of the steering column where it's attached to the column support mount. Check to see if it's broken or pulled loose from where it's attached to the mount.

Some time ago I removed the cover to the underneath of the steering column and had to remove a bolt with the wire attached to the mount. When I replaced the cover I forgot to reattach the ground wire. Later when I went to start the engine, cranked over real nice but wouldn't start. Replaced the ground wire and she fired right up.

Not to say that's your problem, but where the wire is located it would be easy to break it or pull it loose when depressing the parking brake pedal as it's real close to it, on my coach anyway.

One other thing, with the ignition on, have mechanic check fuel pressure at the fuel rail. There should be a schrader valve on the right side where it can be checked. Should have around 35-40psi, if not check the fuel pump relay and/or your fuel pump.

Good luck and let us know the fix.

Another thing to check would be the fuel shutoff or rollover switch. It's usually under the dash near the steering column. If the plunger has popped up it shuts off the fuel pump. Normally it takes violent action like an accident to make it pop up, but sometimes something as little as a bump with your foot will do it.

Seems that I have been misinforming the forum, I apologize and stand corrected......... the v-10 gets power to the coils but does not get anything to the plugs, there is fuel present, replaced crankshaft sensor, pcm module and am losing the battle with my mind.

I am not a mechanic, I'm trying to relay to the forum from my mechanic who doesnot have access to computer. Thanks in advance for any suggestions....Sam Z

you say u hav power to coils? is that 12v power? if so that does not mean the cop is being energized. use a noid light between the two wires on cop (leave it disconnected) and crank engine. it should flash as pcm is telling it to fire. you can repeat for all if u want, but if one is not firing, look furthur. i have 14 yrs experience as a ford class a tech. dont claim to know it all, but can help.
