Well guys after having my TVS 1900 installed on my 08 Sierra (about 3-4 months now) I was told I would not need a fuel pump, but today I started the truck up and it died off on me after starting it up again the rpms went up a little and the truck started idling a little so I accelerated a bit and it seemed to work just fine, it's only done it about 2 times and seems to be working fine after that, the fuel pressure gauge is reading 45-50 psi and it seems low to me for a reason? Could it possibly be a fuel pump issue? Or maybe some type of wiring?

 

If it died you had an issue with Fuel, Air or Spark. I know, Duh.
Does your fuel pressure fluctuate? Can your pump keep up.
Has it happened again?

 

Well it's happended about 3 times, whe the truck is started the Fuel Gauge read 60-63 psi, but after being on for a bit it goes down to 45-50 and just plays around in that area, i doub it's the gauge messing up.

 

I'm having the same issue with mine...fuel pump is only showing 6.3v at 60psi and 5.1v at 44psi which seems way 2 low! Really hope someone can come up with a solution!

 

Yea I'm sure that's the problem, bought my 255...It should be going on this week and hopefully tha'll solve the problem.
