I'm looking in Haynes manual page 12-27....
The problem i'am getting is im not getting fuel past the injectors... I'am assuming all my injectors did not go bad at the same time. The only 2 problems i could see it being is either the ECM or the ignition amplifier and switching module.
I have almost 50psi of pressure up to the injectors so its not fuel pump, filter, or regulator. (Regulator was just changed about 4k miles ago.)
What happens when this module goes bad anyone know?
