need some help with a truck not starting
Ok today is the first day I've driven my truck in awhile but several times its done this today. Ok here's the symptoms my edge monitor will ready 20+ psi and it won't start but earlier when it would read around 4psi it would start now my odds are better playin the lottery than this truck startin when I need it.
What is wrong I'm thinking lift pump but when its runnin I'm seeing 20 psi at idle and around 14-15 wot. Would yall still say lift pump?

I'm not thinking the LP at this time, not yet at least. The VP44 engines will have hard starting with too much fuel pressure. It is possible that the overflow valve in the VP44 itself isn't allowing fuel to bleed off.
You could try just going straight from off, to start. Don't wait for the wait to start light or anything. Don't allow the LP to build pressure.

The lilt pump only runs for a second or two, which may be long enough to pressurize the system. After sitting for a minute the pressure can blead off. Could be the pressure blead off valve located in the fuel return banjo bolt on the VP44. Not an expensive fix, and in my opinion should be part of a scheduled maintanace.
