    5.0gi TBI to Carb

    The engine has only one wiring harness that connects at the back of the boat. Regarding the carb i can work around that but my main concern would be the wiring to get everything going including gauges. I have read some people say its easy while others say they had to cut wires. This is my...

    5.0gi Pefs engine wiring sorta question

    The engine has a buzzer and it was working untill engine was removed. I dont have the engine in front of me so i wont be able to confirm. If it is a negative i can always bypass it to engine block.

    5.0gi Pefs engine wiring sorta question

    Would it be ok to asume that no pins are broken due to 8 wires coming in and 8 pins out. Since 4 is buzzer at the engine harness is that connected internally? All this to put my mind at ease.

    5.0gipefs fuel pressure regulator

    Scott, i got the injectors back from a 2nd testing facility and they passed flow and are matched. If the spring doesn't solve my hesitation/deceleration and engine dying from 1000 to 2000 rpms but not above 2000rpms im sure it will lead to the ECM. Everything else either is new or checks out in...

    5.0gipefs fuel pressure regulator

    Can the regulator be calibrated or is it recomended to replace the internal spring? The reason is i got a hold of 30psi spring and noticed the torx bolt on the regulator sunk all the way in. I did read somewhere that it is permanent calibration. Injectors are currently getting tested, cleaned...

    5.0gi PEFS stalls and deceleration

    Here is a close up of the first time the engine was fired up. The video does not do it justice as now after being installed it is more prevalent. I dropped the boat off at the mechanic today and after a brief view by the mechanic i stated that there is also a noise upon start up after being off...
