Running rough - now no start
Hey guys I need your help. I have a 2007 f-350 with 79,000 miles. Only mod is EGR delete. Truck has been experiencing long cranks and running rough so today I decided to change the oil and filters. I come out of the store and truck will not start. It crank and cranked forever. I let it sit for about 15 minutes and finally it stumbled and started. I drove it home, parked it in the garage and now it will not start. I removed the oil filter and canister fills with oil pretty quick when cranking. Pulled secondary fuel filter and cycled key and it filled quick as well. Also noticed that while cranking there is no oil pressure registering on the gauge in dash. Does this sound like a HPOP or snap-to connector? Any help will be appreciated.
