a98pmalcolm Posted April 6, 2015 Share Posted April 6, 2015 Hey all. After my recent issues from this thread: http://www.mkivsupra.net/vbb/showthread.php?320783-Any-Advice-I-Have-An-Odd-Issue-With-My-Supra To summarise the car was honking out and all looked normal on the ECU datalogs the only issue I can think of is a fueling problem. Would it be possible for aeromotive FPR to go wrong? Thanks Paul Quote Link to comment Share on other sites More sharing options...
Scott Posted April 6, 2015 Share Posted April 6, 2015 Do you have a fuel pressure sensor? If not, if it's a fueling problem, it could be anywhere in the line. Pump, filter, FPR, etc. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted April 6, 2015 Author Share Posted April 6, 2015 (edited) I'm not sure its it has a fuel pressure sensor. Its not a thing I added so if its not a stock thing I'd say no. The pump is only a few years old and I bought the FPR used. I have a pulsation damper bypass so it wont be around there. A filter cant be much so maybe worth doing that 1st...

There's a lot of assumptions being made that aren't justified at the moment. You really need to fault find your fueling. For a start, what does your FPR idle at?

But its a temperamental issue. Thanks for the help with this Edited April 6, 2015 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
Scott Posted April 6, 2015 Share Posted April 6, 2015 Does it cut out randomly, when it's hot, when it's cold, etc. Supply loads of details of the circumstances when it is cutting out. Does it start again easily enough? Quote Link to comment Share on other sites More sharing options...
mellonman Posted April 6, 2015 Share Posted April 6, 2015 A fpr is just a hole realisticly, I doubt it could go wrong intermitantly dude Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted April 6, 2015 Author Share Posted April 6, 2015 Yer it cuts randomly. It fine today and the past few days on the way to work . And start no probs. Just last night i went for a drive and felt a a little blip of it cutting out. Nothing like a few nights ago when cut out a few times in the space of a few miles until it cut out completely and wont start for 20 mins...

Scott Posted April 6, 2015 Share Posted April 6, 2015 What did the FPR read when it wouldn't start? Definitely doesn't sound like the FPR anyway. Next time it won't start check the FPR gauge and see what the pressure is like. Also take note of your AFR when it starts to die. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted April 6, 2015 Author Share Posted April 6, 2015 When it didnt start I didnt check. I thought about that when i for home lol.. Well its been years if at all the filter has been changed so most probably worth doing anyway. Car behaved itself 2day no issues at all...
