Hi Im David, what is the fuel pressure while its running?
and you changed the fuel pressure regulator? when you pull off the vacuum line on the fpr, is there fuel present?
ok, check that, and also see what the pressure reading is when you do pull the vacuum hose off running
it should go up a few psi, but its probably ok. is there a strong smell of fuel in the engine compartment?
ok. you are going to need to check for leaky injectors. not that difficult on a 3.8.
pull the dipstick. if it smells like gas is one way to tell. or pull the spark plugs. if theyre wet, you have leaky injector/s
pretty much none. but i'll think about it.
ok. check fuel pressure with the key turned to the on position,do not start. let me know what it is
ok sounds good
