Had plenty of fuel pressure yesterday afternoon, then this morning when i went to leave for work..boom no more Holley Blue pump i guess the solenoid burned up on it over night ...which would explain my dead pedal syndrome and the sputtering white smoke recently that was intermittant ...so folks..yes a fuel pressure gauge is good..but still won't matter in certain situations...hope ya'll with the FASS systems are having better luck.I shoulda kept my 12 valve

holly pumps suck

Aeromotive or Walbro is the only pumps I ever deal with... this is for gas of course but I would think they dont care

Hmmm. First blue I've ever heard of dying. I agree though, you shoulda kept your 12 valve. You should by the new RASP system and test it out for us.

How old was the pump?

Cummnzpowr

OK update...installed new one EXACTLY like how the other one was set up ground wire, and power wire alike...and it still has no buzzing that it's running what could i have done wrong....i am in deep trouble and about to lose my job if i can't get this thing running...if anyone has any ideas or lives close to the area i'd appreciate the help

Bad relay maybe? Check the relay under the hood that is labeled "Fuel system relay". If that relay is blown, then it won't allow the lift pump (or injection pump for that matter) to run.

Try to give it some juice directly from the battery. Sometimes the ECM-Output is bad. (I'm running it through a relais to the LP)
If it works like this just out a switch in the cab to control the LP- let run for some seconds prior to startup, switch off while cranking and turn back on when engine runs.

It's a quick and very dirty fix, should only be done when you are the only person using the truck.

The relay is definately a good place to check. After the experience that gsdod1 and I had with his truck I will always check the relay before I remove the pump. Another thing to check ist to use a test light across the wiring for the pump, it will tell you if the pump is getting any power.
