2010 Ford Escape 3.0L V6 Limited - prolonged cranking when hot

Hi Scotty,

I have been having a problem for a couple years with my 2010 Ford Escape Limited, 3.0L V6 AWD (Flex). When I first turn the key to start the engine from a cold start, it starts right up, with only about 2-3 cranks of the starter. However, after driving it for 15-20 miles, then stopping (say to go into a store), and coming out, the engine takes 7-10 cranks before it will start. I took it to my local Ford dealer who checked the fuel pump pressure, took it for a road test and told me 'everything looks fine. We can't find any problem, but if you want us to go ahead and start replacing parts we can do that! (I declined). I did check on the internet asking this question and in one YouTube video, they provided a tip to help diagnose the problem. Here is what I found - if I turn the engine key to the first position so that the dash lights up (and fuel pump turns on) but not all the way so engine doesn't crank, and I do that 2-3 times, on the 4th time, the engine starts right up. So seems like I'm lacking fuel pressure on first attempt to start when engine is hot. I was going to just buy an EOM fuel pressure sensor and try replacing that, but I couldn't even find where that was located in the engine. The car has only 27K miles, mainly city driving, and has not had any other problems in the 10 years I've owned it (bought it new). I'm retired now, so do only short trips, in town driving, rarely going on the highway. Any help is appreciated  - the dealer's mechanic was a total waste of time. 

Thanks,

Bob Needleman

 


I forgot to mention - my 2010 Ford Escape Ltd 3.0L V6 had a factory recall involving the fuel rail. Something about a flange needing replacement, potentially causing a fuel line issue. I had the recall performed at a Ford dealership - seems like the problem was not there before the recall was done so I'm suspicious it may have been caused by what the mechanic did to perform the recall but I can't be sure and the dealer is unwilling to make any changes to the job they did for the recall.

When the engine is hot, you need less fuel to start up. Odds are that you get too much fuel in engine and it may be related to bad injectors that spray fuel 

You also said you only do city driving. If you can do some highway driving (60-70 mph) for around 1 hour, it may help cleaning the injectors too.
