So, I know there are a few "hard start" threads on here, i just figured I would go ahead and add mine in hopes of finding some answers.
2001 F450 Dump; 158,000 miles; approx 7mpg at first
Background: just bought the truck about a month ago and have already done the following...
-New HPOP lines and fittings from ford
-New International Bellowed Up Pipes
-Turbo Pedestal O-Rings
-EZ Oil Additive +Cetane booster
After all this she seemed to run great (much better than before and definitely increased efficiency maybe 12mpg at best) and the start up was significantly better and seemed to have more power.
But, just the other day a bunch of things happened all at once.
-Passenger Rear Inside Tire Blew
-Power Steering sprung a huge leak
-Blew the CAC pipe off (greasy boot from CCV)
-After truck was turned off it would crank but not start.
So I replaced the CPS and it took a while to turn over but finally it would start...now it seems to run decent but its realllly hard to start, even after its been running and is warmed up...
Hard Start Symptoms:
-takes a while for the oil pressure to build (see first and third video)..shouldnt the oil pressure shoot right up when you start cranking? Thats what's making me think HPOP?
7 minute drive Towards the end, around 6:00 there is a small uphill climb
Engine off and Restart, Still Hard Start
