WWWPerfA_ZN0W Posted December 13, 2016 Report Share Posted December 13, 2016 Battery and/or starter would be my primary guesses. Even though you have push button start, the pathway may be similar to a keyed ignition switch, so wherever electrical contacts exist, those would be suspect.

SND224 Posted June 15, 2017 Report Share Posted June 15, 2017 I live in Las Vegas and I am having this problem with my 2007 edge. I've had the battery, spark plugs and fuel pump replaced in the last week in Idaho. I come home and it's 100+ and it takes a good 15-20 seconds to start. It does start though but the hotter it is an the longer it sits the more problem it is. It sounds like a fuel issue. Is there a separate filter maybe?

WWWPerfA_ZN0W Posted June 15, 2017 Report Share Posted June 15, 2017 No separate fuel filter, per se. There is a screen directly attached to the fuel pump inside the tank. Does it crank at normal speed in the heat though? Usually some kind of vapor lock would be blamed for this in times past. Is it possible the battery has already gone bad? Check not only voltage but CCAs on the new battery. Sometimes the starter is known to die in the kind of heat you get out there in NV and AZ. May be a symptom of a failing starter.

enigma-2 Posted June 17, 2017 Report Share Posted June 17, 2017 Perhaps a failing cylinder head temperature sensor is worth looking at. One of the effects is a longer crank time. 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted June 20, 2017 Report Share Posted June 20, 2017 SWAG!!! how is the stop switch doing? Is it functioning correctly have you had work performed on the breaks (Akirby) Brake booster. If the stop switch is not working that could cause your non start issue. Just a thought. Quote Link to comment Share on other sites More sharing options...
BrianClearLake Posted March 19, 2018 Report Share Posted March 19, 2018 I am having the same issues. Does someone have the procedure for replacing the ignition switch? Thanks! Quote Link to comment Share on other sites More sharing options...
Tmusick21 Posted June 19, 2018 Report Share Posted June 19, 2018 I have a 2013 ford edge limited and I am having trouble out of it not starting when it gets hot outside. I can roll the windows down for about 30 min. Then it will start all the research I've done leads to the ignition switch. Has anyone installed one? I do not have the push button start.

enigma-2 Posted June 20, 2018 Report Share Posted June 20, 2018 (edited) I have a 2013 ford edge limited and I am having trouble out of it not starting when it gets hot outside. I can roll the windows down for about 30 min. Then it will start all the research I've done leads to the ignition switch. Has anyone installed one? I do not have the push button start. When you turn the key on your hot-soaked car, does the instrument cluster gauges respond, the warning indicators light? (Ignition switch controls them as well).

I'manedgeowner Posted July 5, 2018 Report Share Posted July 5, 2018 (edited) WWWPerfA_ZN0W, I think it's more than just the Edge. I've been told ignition grounding is weak because of safety precautions to isolate the clock spring. This problem isn't common but it's not rare either on F150's and light duty 250's. enigma-2, If this is the same problem as the trucks than the instrument cluster works normally. Everything seems to work normally except it doesn't crank. Edited July 5, 2018 by I'manedgeowner Quote Link to comment Share on other sites More sharing options...
BrianClearLake Posted July 6, 2018 Report Share Posted July 6, 2018 Sorry for the delay in replying. When the vehicle sits in the hot sun, temps close to 100F, I will get all my correct lights on the dash, stereo works fine, but when I go to turn it over, nothing....just nothing. No clicks, its not the starter. Open all the doors and pray for a breeze. After 15-30min it starts right up. This is the model with key start on the dash.

Mark edge 13 Posted April 9, 2019 Report Share Posted April 9, 2019 Finally I found the the issue. The issue is in the shift that connect the cylinder switch with the ignition switch. So the ignition switch for the MKZ and the Ford Edge is crap and made from plastic, if the shift (made also from plastic) did not engage completely with ignition switch, the car will not start and will not make any sound, even though all the dashboard light working and radio working. To solve this issue is more easer than you think. after remove the ignition switch, there is a black shift that have half circle grove. Cut papers like a halve circle and put it in the shift grove. How many paper and the thickness of the paper is important. I putted 5 halve circle papers. So those papers will make the shift longer, which make the ignition work bettter. I hope this will save people money and time. 1 Quote Link to comment Share on other sites More sharing options...

Ahmed Alhamadani Posted June 11, 2019 Report Share Posted June 11, 2019 I have exactly the same problem with my 2013 Edge Limited. When it's 100+ outside and leave my car under the super hot weather conditions, it does not start until trying too many times. Please, if anyone can help?

WWWPerfA_ZN0W Posted June 11, 2019 Report Share Posted June 11, 2019 Does the starter turn over and the engine does not? Or does the starter just click? How old is the battery? Have you checked the Cold Cranking Amps? Heat is a battery killer. Quote Link to comment Share on other sites More sharing options...
Abdullah Alghamdi Posted August 20, 2022 Report Share Posted August 20, 2022 I have exactly the same problem with my 2012 MKX. The car starts normally with no problem in a cold or cloudy weather. However, in a sunny and very hot weather, the car will never start until the weather gets cooler or after the sunset. I took the car to a dealer to diagnose the issue using a computer inspection. He did the inspection and the computer diagnoses two issues PCM and ignition switch. He said it could be one of them. He recommended me to start with replacing the PCM and if this did not solve the problem then jump to the second and replace the ignition switch. Did anyone have the same issue and after replacing the ignition switch everything went well? Quote Link to comment Share on other sites More sharing options...

To me it sounds like that dealer lacks the skills to properly diagnose the issue - if possible find another dealer or make a deal with that one that if his parts replacement doesn't resolve the issue, NO PAY.

WWWPerfA_ZN0W Posted August 20, 2022 Report Share Posted August 20, 2022 what are the symptoms when it fails to start on hot days, @Abdullah Alghamdi? does it crank normally or not even crank? do the lights on the dash come on normally? does the security light flash slowly or does it become faster when cranking? starters are known to fail during temperature extremes.

Jared4454 Posted February 26 Report Share Posted February 26 Most of the time this no cranking when hot is going to refer to a bleed back of the fuel system leading to fuel pump replacement. Lot of people have this problem. Not a ton of info out there. Quote Link to comment Share on other sites More sharing options...
