Hi, I have a2013 F150 3.5L Ecoboost that will not run.
I have proven fuel and spark. The engine turns over and "tries" to fire but it doesn't catch.
Anyone have any ideas?
Thanks

Spark is fairly easy to ascertain, but how did you prove fuel? You may have a pressurized rail, but no injector pulse. Either that or a failed FPDM. I suspect you don't have fuel.

Thanks for the help. To prove fuel i hooked a hose up to the low pressure supply. The flow looked good to me. For the high side i backed off the connector a touch and had someone watch as i turned the key. It looked good as well. I tried every fuse and relay i could think of. had a few people listen as well....lots of head scratching. I checked for spark with a tester and everything looked good. There was a recent severe cold snap so I am guessing this is a result of that. I am sad to say the tow truck is on the way. I will let you all know what they find at the shop.

The shop said the engine was flooded so bad that the CATs may have had fuel in them. I think the reason was due to a weak starter and the extreme cold. Starter didnt turn fast enough the first time i tried. It was so cold that i believe the fuel never evaporated when i let it sit. Each time i tried just made it worse. I have never seen this kind of issue before. Thank goodness it wasnt too pricey.

If it's still not starting have you tried a little squirt into the intake?

THIS JUST happened to me. Cold snap minus 50 sat for a week not plugged in, I knew it was the starter, shop charged me 347 for a new starter. Then told me there was fuel in my oil. That its cost 687 extra to change the spark plugs i changed just last June and an oil change. What did they do to yours and how much did ththeththey charge u???
