Default Intermittent starting problem

I own a 2003, 2.3L, 2WD, 5-speed Automatic.

The problem I am experiecing has happened 3 times now. The first time about 5 years ago, but the last two within the last 5 weeks. After driving and running errands for instance I will get back in, and the truck will fail to start. It cranks real strong but won't fire. Five weeks ago I had it towed to the mechanic. The following mornig it started right up for them. They hooked the analyzer up but no error messages were indicated. It drove just fine in the mean time. Today it happened again. Drove to the doctor and on the way home stopped for breakfast. Got back in and wouldn't start. I let the truck sit for an hour and a half and it started right up. Any ideas of what might be happening?

Thanks, David.

Sounds like a vapor lock, drive around for awhile, and take it to a mechanic, have them check fuel pressure. Just my thought. Somewhere in your lines your fuel is getting warm and turning to vapor, that the injectors can't inject. Hence vaporlock. This is just my thoughts, there could be a bunch of reasons.

Other things to check:
Is there spark when cranking
check your wiring to your PCM and the rest of the truck, may have a wire that is bad
When was the last time you changed the fuel filter

That's all I got at the moment.

Thanks Richard, I will give your suggestion a try. I will have to check my records but I believe I had the fuel filter changed a year ago.

Other forums I have read indicated the inertia switch may have been triggered, but the way I drive this wouldn't make sense; on the other hand the description the other Ranger owners describe is identical to mine.

Maybe the Inertia Switch. I had a similar problem. Bought a brand new switch from ford for cheap, and everything worked fine.

The inertia switch in a Ford can be your best friend and your worst enemy. If that's what others are telling you (because I didn't think about that one) then I would start there. It is pretty cheap and easy to fix. If you can find it, there is a reset button on it, so when the engine starts doing this crap again, go find the inertia switch and hit the reset and see what happens. They do wear out after awhile, and then cause problems. Had the same thing happen on a buddies Bronco here a couple years ago.

Ford solved this problem by the time they got to his truck, yours is old enough to have that problem from my understanding. I could be wrong, no disrespect ment either

next time it does not start, check for spark, you can do this by spraying starter fluid into the TB.........you want to isolate if it is fuel or spark?.....I would think if it was the inertia switch you would need to reset it to get it to run. Does a 2003 have an ignition module? I would look at the fuel pump relay and the fuel pressure........ do a fuel pressure test..... i agree with the poster that siad the vapor lock............also run a different brand gas in it and add some techron

I had the same problem with my ranger for 4 years. It would run fine and i would stop somewhere for a few minutes
and when i tried to start the truck, it wouldn,t start, unlesss like you said let it sit for 1 or 2 hours, then it would start fine. So finally one day
the truck wouldn't start again and it wouldn't start for the mechanic either. Try changing your fuel pump relay. It's never happened again.

Fuelpump relay is a possibility. Next time it will not start spray some starter fluid into the TB that willhelp determine fuel or spark

I had a similar problem on my wife's Ford Contour. She drove it to the hardware store and came out and it would not start. It turned over fine. Let it sit for a couple hours and it started right up. It turned out to be the fuel pump. Replaced the fuel pump and it was fine.

This problem started to happen after we let the car get very low on fuel. A friend who worked at a Ford dealer said that letting the fuel get really low causes the fuel pump to overheat because the fuel cools the pump inside the gas tank. If you ever run out of fuel or let it get very low, you can damage the fuel pump.

Have the fuel pressure tested and if it is low, then it is the fuel pump.

I had the same problem for two years till one day it wouldn't start at all. Had
it towed in and the problem all along had been the fuel pump relay.

----------

I would definitely have the fuel pump relay replaced because it's not
that expensive and it could solve your problem.
