For context this is a yard truck that I use for plowing and moving wood. It'll never be on the road again. I just need it to move snow. I have spark and the injectors are working. When I dump fuel into the throttle body, the truck runs and idles but wont start unless I fill the bowls manually and it only runs until the fuel i've bottle fed it is gone. I'll post a link to a video of the injectors working. It looks like there should be enough fuel coming from the injectors to get it to at least try to start on it's own but I get nothing. The gas in the tank is only a couple months old and is Ethanol free so it should be fine. My oil pressure gauge has been pegged since I got the truck. Some folks are saying that sensor being bad would keep it from starting because it helps control the power to the fuel pump but it was pegged all last year while I was plowing and never kept the truck from starting. The truck has always started hard unless it's warm when it starts quickly. It'll crank for probably 5 seconds and it sputters a couple times before it finally fires up if you're starting it cold. I verfied spark with a cheap Harbor Freight inline spark tester but I do have spark on the two cylinders that I checked which were 3 and 4. Maybe a weak coil or a bad cap and Rotor?
The sputter you hear when I start cranking is the residual fuel left over from when I filled the bowls manually. Without bottle feeding the fuel directly into the bowl I get nothing. No attempt to fire on fuel coming from the injectors. To me that says that either the injectors aren't delivering enough fuel, the fuel somehow isn't making it's way through the throttle body to the cylinders, or I'm not getting enough spark.
Things I've already changed:
8 Brand New Spark Plugs
ICM
Fuel Pump Relay
Fuel Filter (I didn't change it but it looks like it's only a few years old, definitely not original)
Where should I go from here?
