Pro tip you can back fill the air tanks to get rid of the noise a majority of the time
@usfarmcop Oh Yeah!! Thanks for sharing!
I enjoy these buses from the summer.
@ivanpeterzell695 They are pretty nice!
Would it have not been easier to connect the wiring harness to the suspect ECM without removing the known good ECM and see if coms and a start could have been initiated? or were the wires not long enough?
@JohnSmith-wb6kq The wires were not long enough!
I've got a question about a 7.3 I've narrowed it down to either the PCM or the HPOP how do I test the HPOP
@donaldsterling9305 remove the ICP Sensor and use a pressure gauge in the sensor hole to check injection actuation oil pressure while cranking, it should be between 700 - 900 PSI while cranking!

@martinarrieta248 My Pleasure!
Feedback - dont make a video with an ear piercing alarm noise.
@SoldfMC Sorry for that noise, the buzzer was hard to get to and we couldn't find the fuse for it! I hope it wasn't too bad!
