The PCM you replaced,did numbers match old Pcm?


when i use a scanner to see if i have and codes my scanmner reads link error i have tried two scanners is there something else should i ck the gas guage also reads empty and i know i have a full tank i also pulled a plug and it is dry


Check the fuel rail for fuel,may be bad fuel pump or relay,


All so a bad fuel pressure regulator will do this.


i checked fuel pressure on the fuel rail and i got 40psi when eng was cranking


Have you checked the crank sensor?You said you already replaced cam sensor.


Did you just check it or replace it?


but the main problen is i have no spark after replacing the pcm cam senor and crank senor also asd
