I already reset fuel cu off - 12vdc before and after switch
Thank for the message from disco mike because i clean crank sensor electrical connection and then turn on the engine but after 3 minute start to give me a rpm erratic and then shut down like crack sensor intermittent failure i will...
Fuel pump relay
Yes i swap the relay . I already have 12 Vdc on relay terminal #30 all time and 12 Vdc on terminal #85 when switch is on II position but only read 6 volt from 85 to 86 , and when i read from 85 to battery negative terminal i got 12 vdc
Master Swicth on position II i have 12 Vdc on pump relay but the ECM dont give me the ground to operate the relay. I jump the contact to send 12 Vdc to fuel pump and work perfect.
somebody have any idea
