Truck is a 2003. It will try to start and sometimes it will and rough idle for 3-5 seconds then shut off. ICP gets up to 1500 while cranking and IPR gets to 85%. I don't have a good way to read fuel pressure but pump does run and if I crack fuel filter housing open while pump is running it seams to have a lot of pressure. Truck also showed no running bad problems before the no start issue. Only codes are P0403 EGR circuit fault, P0405 EGR A circuit low, and P1000 OBDII system checks incomplete. Truck also passes injector buzz test. No programmer on truck just exhaust intake and EGR delete. Any help would be much appreciated. Thank you.
