Just put everything back together after cleaning and now truck wont start. Its trying, but thats all, i am lost. There is a upside down empty triangle on dash and it says warn engine, but thats it. I feel dumb necause it all worked fine before i tore it down. She leaves in 12 hours for grovestown, from here in iowa and im looking for advice. I did checkover all that i took apart. The only thing i was 100% unsure of is the 2 lines that connect to the swnsor on top of the dpf can, i changed that sensor as well and am not positive i got the lines on the correct nipple on the new sensor, past that im stumped. I also changed the fuel filter"devco". Thats about all i know now. 2010 pro star with isx
