NewZed Posted July 29, 2011 Share Posted July 29, 2011 What is it that "goes away" when you shut the car off, after letting it run for a while? I saw your other post, which is more descriptive since you say that you have spark. If you have spark, and the engine turns over, and it ran just a few seconds earlier, then fuel would be the place to look. Do you have fuel pressure on the second try, and are the injectors firing?

Do you have fuel pressure on the second try, and are the injectors firing? not to sure what your referring to that "goes away". i am sure the injectors are firing but ill check fuel pressure again when i get the tool.. i doubt fuel is the issue though.. simply cause i can only start the car once. and that i could even let it run and warm up if wanted.. i didnt get the chance to see if the idle drops and stays to a nice number because i had to shut the car off earlier.. so im waiting for that chance again.. when i can start the car...

wolfman_dlc Posted July 30, 2011 Share Posted July 30, 2011 (edited) Once a day, every day, at the same time of day, so many hours apart? Outside, in garage? Sounds electrical in nature to me. Are the AFM and crank angle sensors new or used parts. Not 100% sure but does it matter how you put the disk in for the cas, upside down or right side up? Try bumping the ecu while its running, sounds strange but mine had a faulty chip. It would die out of nowhere and refuse to start again till it wanted. Bumping the ECU or any vibration may give it faulty reading change your timing and fuel output. Just some Ideas!

wolfman_dlc Posted July 31, 2011 Share Posted July 31, 2011 yes the cas does go in only one way, but I was talking about the degree wheel. It can be turned over, still not sure if it matters tho. Quote Link to comment Share on other sites More sharing options...
WaiDai Posted August 3, 2011 Author Share Posted August 3, 2011 http://memimage.cardomain.net/member_images/7/web/403000-403999/403158_270_full.jpg i noticed 2 hoses that are not connected. can someone tell me where the 2 skinny hoses that go over where it would say turbo go to? i realized one of em has vacuum and the other doesnt. im guessing one plugs into the cruise control thing? while other i have no clue.. someone let me know please =] pictures would be beneficial.. i tried looking at fsm but i just have no idea what the units are called that it is plugged into..
