heavy85 Posted December 24, 2009 Share Posted December 24, 2009 I just bought a '92 E-150 with a 5.0 (302) to tow the Z. It's only got 80,000 miles and in general is in cherry condition. However, when cold it starts right up then dies several seconds later. It floods out and I know that because when it restarts you can smell the half burnt fuel. If you try to start it back up it just cranks unless you floor it then it will start right back up. You have to keep it reved otherwise it will die again. Once it's a bit warm it runs and idles smooth. There are no lights on the dash other than the rear ABS and the temp gauge bounces around. Any ideas where to start? Since it's fuel injected I'm confused why flooring it allow it to start right back up like it's got a carb? Since this is Ford V-8 tech land I was hoping there would be someone who have seen this before. Thanks Cameron Quote Link to comment Share on other sites More sharing options...
Zmanco Posted December 24, 2009 Share Posted December 24, 2009 Most fuel injection systems interpret a WOT during cranking as a flooded engine and stop injecting fuel until the engine starts. I'll leave it to others who know the specifics of Ford FI to suggest where you should start. Quote Link to comment Share on other sites More sharing options...
Capt_Zorro Posted December 29, 2009 Share Posted December 29, 2009 Take it down to Auto Zone, they will scan it for free. Sounds like a bad sensor or broken, loose connector or wire in the cold start circuit. Quote Link to comment Share on other sites More sharing options...
heavy85 Posted December 31, 2009 Author Share Posted December 31, 2009 OBD1 - Autozone doesn't have a scanner for OBD1 unless you want to buy one ... guess there's not many Ford tech on the board? Cameron Quote Link to comment Share on other sites More sharing options...
NeoTokyo Posted January 1, 2010 Share Posted January 1, 2010 Idle Air control seems like, clean it out and see if it helps as it can cake up pretty badly. Make sure to get a new gasket for it. It can also just fail so you may need a new one. Also use some MAF cleaner and clean the MAS. Do your reg maint on it from plugs to fuel filters, its good practice anyways just to do it all at one time. Good luck. -Eric- Quote Link to comment Share on other sites More sharing options...
Sven Posted January 1, 2010 Share Posted January 1, 2010 Autozone has code readers that will work. Don't get hung up on the OBD1 crap, you just need a run of the mill EFI code reader or flasher with a Ford adaptor. Or, you could just get the CEL codes and start counting flashes. I forget what the trick is to trigger them, it's been a while since I bought my reader. Quote Link to comment Share on other sites More sharing options...
