Ford Flex no start

A couple of months ago the car would crank but not start. Towed to dealer and it started for them, of course.

By luck and good fortune I found out about the NHTSA website which has a huge database of car complaints. A lot of complaints about the Flex not starting and the solutionƒ??replace the Fuel Pump Control Module which is easyƒ??remove passenger side C pillar cover, remove bolts, unplug, plug in new one ($38 plus tax) and now the car starts.

There are dozens of YouTube videos showing how to diagnose and replace. I didnƒ??t diagnose, I just took a chance.

After that I thought why couldnƒ??t you just jump across the connections because the thing is really just a switch. And I found a Flex forum thread where the poster was hundreds of miles from home with no way to get the part so he did exactly that and it works. He said the only thing is in an accident the pump wonƒ??t shut off so best to only jump it in an emergency.

This happened to a customer of ours when I worked at Goodyear before. It was a Taurus but same engine as the flex. It would only act up below a certain temperature. Also the part was a lot more expensive then as this was almost 10 years ago.

@sergeant-schultz?ÿ

A YouTuber I watch sometimes is currently reviving one of those Chevy Luvs in his videos. The engine ran after sitting over 20 years I think.?ÿ

My dad and uncle (his brother) bought a 1915 Ford Model T that had beeen siting in a garage for over 40 years.?ÿ Before they loaded it on the trailer to take it home my uncle said, "Just for fun let's see if it starts" They added a little gas, turned the hand crank and CLACKETY, CLACKETY, CLACK it turned over and ran.

My cousin later broke his arm trying to start it with the crank.?ÿ A common problem I've heard.

I've read the problem was caused by not retarding the spark (a manual adjustment) allowing the engine to backfire, i.e. turn backward.

The crank fitted into a tapered notch so that when the engine started normally it would kick the crank out an inch or so to disengage it. When turning backward, of course it stayed engaged and swung the crank around to hit the arm.

I'm sure Uncle Paden can describe it more clearly.

I think Bill is suggesting you might be older than you really are.

Defend yourself.

I was suggesting that Paden knows far more about automobiles and their history than I do.?ÿ That good video does tend to confirm what I said, though.

A story was related to me: Crown Vic police car involved in accident, fuel pump relay stuck closed (mightƒ??ve been like that before) and as a result fuel was pumped onto hot destroyed engine causing a fire. Mine stuck open. So itƒ??s a safety issue.

In the mid-70's I worked on a farm that was owned by a man in his late 60s.?ÿ He'd grown up there, and all the equipment was old.?ÿ His "big" tractor was a John Deere Model D, which had to be hand-cranked.?ÿ He taught me never to wrap my thumb around the crank handle, instead always to make sure to grip it in a way that a backfire would cause the handle to just roll off my fingers.?ÿ He said that wrapping your thumb around it was a good way to break your arm.?ÿ

my first tractor was a John Deere model 'A' had a wheel to turn.?ÿ Backfire would just scare hell out of you.?ÿ Darn thing had more torque that anything I have had since.

I recall it had duel fuel, high octane to start and would run on most anything that would ignite.

Here's a little known attachment for Volkswagens which I religiously kept on all my VWs.?ÿ J.C. Whitney used to carry them in their catalogs.?ÿ It was merely a plate that installed under the generator pulley that had a notch for a knotted rope similar to how we used to start lawnmowers (only old timers will remember this).

My 1941 Ford actually had a hole in the chrome grille where one could use the sprag on the end of the jack handle to crank start the old flathead.?ÿ According to my father some folks were die-hards when it came to trusting electric starters on autos.?ÿ Apparently a way to still hand crank cars was common on most pre-war cars.

I never attempted to start that old Ford by hand...even in my young and dumb days I had a little bit of common sense.?ÿ 😉

The D could be started by turning the flywheel directly as well, but I didn't like having my fingers that close to the moving parts.

I've heard that some modern motorcycles now have electric starters

@jim-frame

My dad said the same thing, fingers only and no thumb around the crank. And he made sure I remembered it, even though he knew I'd probably never have to start a Model T or anything else with a crank. He said that a Model T owner with his arm in a cast was a common sight back in his day.

He also said the Model T crank was set up so the engine fired with the crank at the top and bottom of the stroke. It was harder to control the crank handle in that position. Some people used to take their Model T crank to a blacksmith and have him heat it up and give the end a quarter turn. That put the firing position on the left and right when you were cranking.
