Do you really think the injection control pressure is an issue? It's getting well over 500 psi crankingl since I replaced the IPR three days ago.Well, you have several things going on. It all adds up. You have borderline ICP pressure. Who knows about fuel pressure, and at least one injector spool valve not working. I can see that being enough to cause a no-start.
Hopefully cranking with low voltage hasn't caused issues with the FICM.
Which connector? Also, yeah, that's got to be fixed, quit F'ing with it until that's fixed.While cranking I think I noticed FICM Sync toggle from 1 to 0 once so I pulled it out to look at it. I attached a picture of the connector. A lot of bare wire. The sensor was missing the upper oring so when I go into O'Reilly's in the morning I'm going to pick up a new one. Any clue why they have a sensor listed at $40 and the connector at $54?
