Truck stalled and dies at stop sign, won't restart. 08 6.4

Customer Question

Truck stalled and dies at stop sign, won't restart. 08 6.4 f450. Replaced filters that were very muddy/murky. Not rusty, but muddy due to bad diesel I believe. New filters, sucked all diesel out tank and blew fuel lines clear. Still won't restart. Checked fuel pressure by schrader valve and it shows 2 psi with key in run position. Not sure if we have air, pump is bad or what problem is

Hi. The spec for the low pressure fuel from the pump on the rail is 5-7psi. You probably are going to have to replace the fuel pump to start with.
