Posting for a friend who doesnt have interweb access........

He has a 94 ES300 has great fuel pressure at rails but still nothing after replacing fuel pump any help

i know its fuel related though just squirted gas through the intake revs up perfect

so its gotta be something telling it to not feed it

can get it to run if you barley touch the peddle anymore after that it is trying to die

but you can open the butterfly squirt gas in and it will rev all the way to the rev limiter

 

anybody ?? he kinda needs to have this INFO asap its for his wifeys car thanks In advance !!!

 

ok put new pressure regulator on today nothing he clamps off the return line and kinda runs good

 

these are tough ones...have u changed the fuel filter??? maybe some restriction there...

 

maybe the mass air flow sensor is dirty????
