I have an 89 Supra Turbo that I recently changed motors and am having trouble getting it going. First let me explain it has a 57 trim turbo and a walbro 255 fuel pump. Upon initital start up I had a Lexus AFM but kept getting the 31 engine code so I switched back to a stock afm to see if it would run better. The engine idles well now and throws no codes, but it will not take gas. When you try to accelerate it bogs and chokes off.Every plug in and innercooler connection have been carefully checked. It is timed at 12 degrees, does any one have any ideas why it wont take fuel?..thanks...
