Increased fuel psi?

[jamerman09]

My fuel psi usually sits around 62 psi. I noticed this evening it was around 70-72 psi. On acceleration it got up to 80psi. It also started idling rough as well. Any thoughts as to whats going on?

Never seen fuel pressure go up when accelerating, usually goes down.

injector stuck closed?

[jamerman09]

Not sure how could I tell? I'm running a Cts monitor. My injectors had been fully reworked less then two months ago.

Fuel pressure sensor could be going bad too. That's what happened with my edge fuel sensor. Look at what the pressure reads with truck off, key on. Should be zero, if it's reading anything higher, sensor is bad. Mine was reading 40 with truck off, key on and at 100 when driving.
I had same symptoms as you. Pressure on day just started rising higher and higher till it maxed out at 100. Haven't had a chance to replace it yet though

I thought with the key on engine off the fuel psi should pressure up to 60psi or whatever..? I dont know but how would the trk start with no fuel psi?

The pump will turn off after 20-30 seconds of KOEOff. The pressure will bleed off fairly quick.
