I assume this is an EGR DT correct? If so, more than likely you have a low ICP issue causing the no start condition. Without a scan tool its gonna be hard to verify. check the basics 1st.Does the check engine light illuminate on key on? Fuel pressure should be around 40 psi cranking up to 65 psi. Oil pressure should at least be 20 psi. On the EGR DT low icp could either be blown rail orings, faulty IPR valve or IPR wiring, or a bad HPP. ill post info on how to get dash engine codes. Ive never done it to tell the truth. Ive always had my laptop. hehehe I should have read Bruces post. Its there for dash code retrieval. If you get a 335 code out of the flashes Its unable to build ICP while cranking. Let us know.
