DCSport Posted July 14, 2014 Share Posted July 14, 2014 You will need this to test the fuel pressure since there is no test port: http://www.ebay.com/itm/Ford-OTC-310-180-Fuel-Pressure-Hose-Test-Adapter-/360978050625 The SCT tuner cannot monitor spark signal on it's own. With COP you'll need an inductive tester and an oscilloscope. I would have done all this long ago, but the problem is trying to catch it when it happens since it is so sporadic and usually starts right away on the second attempt. Cool thanks for sharing that. Yeah I was thinking of setting something up with gauges inside the car to monitor those things during every start, so I can catch it happening and narrow down what is causing the issue. It's obviously either not getting fuel or not getting spark! Do you know if the SCT tuner can observe fuel pressure at least? 0 Quote Link to comment Share on other sites More sharing options...
DCSport Posted July 14, 2014 Share Posted July 14, 2014 Might be easier to setup a 12V light indicator wired to the fuel pump relay at the wire going to the pump....may be able to do something similar with spark? Not sure, will have to check out the wire diagrams later... 0 Quote Link to comment Share on other sites More sharing options...
Fusionpursuit Posted August 2, 2014 Share Posted August 2, 2014 I had similar problem a few times a month, Dealer diagnosed my battery and said "need to be replaced" with a Motorcraft MAX a while back and it never happened again 0 Quote Link to comment Share on other sites More sharing options...
DCSport Posted August 3, 2014 Share Posted August 3, 2014 I had similar problem a few times a month, Dealer diagnosed my battery and said "need to be replaced" with a Motorcraft MAX a while back and it never happened again Hmmmm...you may have gotten lucky. I replaced my original battery last summer with a Motorcraft battery and still have the issue every now and then. Sometimes I can go several weeks without the issue happening....it is very random it seems. I've had it happening since I got the car new. 0 Quote Link to comment Share on other sites More sharing options...
Carol Robidoux Posted November 12, 2014 Share Posted November 12, 2014 Has anyone ever figured this one out? I had my 2012 Fusion towed back to the dealer a few times while it was still under warranty. Some mechanic finally decided it was the accessory adaptor that I was leaving plugged in. It's a tiny little thing. Anyway, it's happened several other times, plug in or plug out. Also, last winter my fan would cut out from time to time - no hot air or defrost (not great up here in NH). They told me I needed a new blower motor and replaced it, at my cost. But then it happened in the summer, my AC cut out the same way. I swear something electrical is not right. 0 Quote Link to comment Share on other sites More sharing options...
GCFF2010 Posted December 31, 2014 Share Posted December 31, 2014 I also have this problem as well. Every once in like 3-6 months the car seems to struggle to start. It also would shake a little violently while struggling too! The dealer has no idea. I have a 2010 Fusion SE 2.5 Manual tranny, and it seems to have the same problem as everyone else has... Mind blowing... 0 Quote Link to comment Share on other sites More sharing options...
PARRMICH Posted February 9, 2015 Share Posted February 9, 2015 Ditto this issue. 2012 3.5L engine, I bought this car about 4 months ago and it's done this to me 3 times now. insert key, switch to 'start', starter cranks the engine for several seconds, turn key off, switch key to 'start', ALWAYS starts up the second time. What's the deal? After reading though this forum it sounds like it's not: Battery Starter Throttle body grounding strap purge valve Anyone else have any bright ideas or resolution to this issue? 0 Quote Link to comment Share on other sites More sharing options...

Welcome to the forum, PARRMICH. Have you had your dealership take a look? How many miles are on your Fusion? I'll do some research to see how I can best assist.

Robert_W Posted April 8, 2015 Share Posted April 8, 2015 I read that their was a big problem, and this person told them to re-wire the whole engine electrical system. As to getting it solved, I do not know. I read this on 'Car complaints dot com', investigating any issue after I bought my 2010 sport 3.5L select shift 6speed. I hope I will not have much problems with this car. Do not have any real "maintained" records from the first owners. And the used car dealer got a junk "CARFAX" that tell you crap. 0 Quote Link to comment Share on other sites More sharing options...

DCSport Posted July 17, 2015 Share Posted July 17, 2015 https://m.youtube.com/watch?v=k5jeMneCriM Who knows what's the problem? Thx!!!! Seems similar to what mine does randomly, except it won't start unless I turn the key back off then back on again. 99.9% of the time it fires right up on the second try. 0 Quote Link to comment Share on other sites More sharing options...
5_inline Posted July 17, 2015 Share Posted July 17, 2015 (edited) Seems similar to what mine does randomly, except it won't start unless I turn the key back off then back on again. 99.9% of the time it fires right up on the second try. It occurs only in the hot matches, but 90% of the hot starts!!! Never occurs in the cold start!!!It's the fuel pump that not stanque??? The power of the motor is normal!!!

Auturfman Posted November 16, 2015 Share Posted November 16, 2015 Sorry to bump this thread but was a solution ever found? This is the exact problem I have with my 2008 SEL and 3 dealerships and numerous shade tree mechanics have no clue what's wrong. Always starts on second attempt, and usually happens 1-2 times per month. 0 Quote Link to comment Share on other sites More sharing options...
jlong Posted March 7, 2016 Share Posted March 7, 2016 Just wanted to post back in this thread and say it still happens to mine randomly. Always starts on the second go. I've gotten in the habit of if it doesn't start after 4 seconds I turn it off and restart it. All cars have their quarks and this is just the fusion sport's quark. It doesn't effect anything else as far as I can tell. I have 111K miles on my 2010 and it runs just fine otherwise, well with the exception of the MS sync sony nav Bluetooth phone issue. I fully expect to get another 5 years out of it which should take me to about the 200k mile mark. 0 Quote Link to comment Share on other sites More sharing options...
man114 Posted March 11, 2016 Share Posted March 11, 2016 Supposedly TSB 07-02-03 fixes this don't know how many model years it covers, it's a PCM flash. Started for me around August when I hit about 55k miles. Dealer knew exactly what I was talking about when I mentioned it, flashed the PCM. Not sure yet if it's fixed the problem. 0 Quote Link to comment Share on other sites More sharing options...
Chsanders Posted February 18, 2017 Share Posted February 18, 2017 I have a 2008 Ford Fusion just last Friday I had to replace my alternator one of the belts and get an oil change cost me almost $400 today my car started just fine no problems battery light popped on for like maybe 10-15 minutes I went on about my day park my car at my mom's house and spend some time with her and it was maybe sitting for two and a half 3 hours I went to leave and my car wouldn't start it wasn't clicking or anything like that it was just trying to turn over like normal but couldn't completely start does that make sense? I took it to the place that replace my alternator and the belt and they check the alternator the alternator sign they disconnected the alternator from the battery and tested the battery and they sent me over to Interstate Battery to get a new battery I had them check everything out I said how much new battery cost that I wouldn't need a new battery but the battery was fine and it started up just fine for them and they start nothing wrong they couldn't find anything does anybody else have this problem or does anybody else have any answers because I can't afford to not have a car 0 Quote Link to comment Share on other sites More sharing options...
