No start with codes
Got up yesterday and the truck would start. Turns over just fine, but won't fire. Checked codes and got p0403, p0404, and p0405; all egr related issues.
I'm going to pull the egr and clean it, but my question is, would these codes cause a no start? I haven't had any issues with performance that I read are normally happening when people get these codes. Just wondering if I may have another issue along with the egr problems.
Thanks in advance.

What is the ICP reading? Needs 500+ to start, I'd check that first. Pull the ICP plug and let the PCM use default and see if it starts that way.
Friend of mine recently had the same issue, turned out to be a chaffed wire on the ICP pigtail.

I got it!!! From under, I reached up and over the heat shield. With one finger, I hooked the clip and slipped it off. Did see some oil on the connection, so I think I'm on the right track. Charging the batteries up and will report back once I can turn it over. Thanks for the help so far!

Ok, so after killing the batteries leaving the hood open and stereo amp running while trouble shooting, I have the batteries charged back up and the ICP disconnected and still won't fire. I'm checking that I'm getting fuel to the upper filter right now, can anyone suggest where to look next? Thank you in advance!

Do you have a ScanGauge II or Torque Pro to use and read the actual values? Need to make sure your getting 150RPM for the starter also, sync needs to happen... really need a gauge of some sort now.

Ended up with too little time to see this through to the end and took it to the dealer. Had a bad cam position sensor and harness and icp was going out, it had "low" readings. Got it back and it runs as good as ever. Thanks for the help.
