Have a 2001 F 350 with a 7.3 liter engine. It's got a crank but no start, solid idle then dies suddenly like someone turned the key off. When we can get it to stay running, won't go above 45 miles per hour. Replaced the ICP and the IPR with no difference. It's pulling p1670, p0603, p1316 codes also pulled a P0 264 and p1298. When it first started acting up last week we did an oil and oil filter change and fuel filter change. Fuel filter had quite a bit of oil on it. Just need help pinpointing a cause, can't keep replacing all these expensive Parts. Tested IDM wiring harness with multimeter, driver side all read around 4.0-4.4. Passenger side all read 6.8-7.1. Any idea why so high and different?
