Hey there, I am newer to diesels and I've got a 97 f250 7.3 with around 260k. I just changed the fuel pump the other day and truck drove perfectly fine and even started back up after I went into the store but then I parked it and the next morning it would only crank. I'm not getting a WTS light either. Also checked fuses and changed GPR and have tried cycling it but still nothing but cranking. Any Ideas? Thanks!
