2000 Toyota Tundra 4.7 Fuel Pressure Test

Read the number on the gauge.

2000 toyota tundra 4.7 fuel pressure test. When it dries out the fuel tank cant hold pressure anymore. 2000 Toyota tundra 47 engine loss of power pops through 2000 Toyota tundra 47 engine loss of power pops through the throttle body random cyl miss fire installed fuel pressure tester at fuel rail running fuel pressure starts out at approx 35 PSI then drops. With the ignition switch ON and the fuel pump running the fuel pressure indicated by the fuel pressure gage should be 333-376 kPa 48-55 psi.

A mechanic has a wide range of instruments at his disposal to diagnose what would be causing the P0446 in your Toyota Tundra. I do not see a port on the fuel rail or anywhere near by.

If you missed. Risk exists of blowing coupler hose off of pump. Misfire When the fuel pressure regulator fails it can allow too much or too little fuel into the engine.

I would recheck all your vacuum lines that you may have removed you replaced the plugs. Unplugging or adding vacuum mightyvac to the pressure regulator makes no difference. Since you have the fuel tester do a fuel test and is low readings replace filter and do the test again Fuel pressure regulator Fuel pressure at no vacuum 265 - 304 kPa 27 - 31 kgfcm2 38 - 44 psi no vacuum 226 - 265 kPa 23 - 27 kgfcm2 33 - 38 psi Fuel pump Resistance at 20 C 68 F 02 - 30 Г.

It is a constant 22 psi. Its on the left side of the cylinder head right below where the PCV valve is if I remember right. Its not really a quick connect since it requires a special tool or at least a couple picks or small flathead screwdrivers to get it to release its actually kind of a pain in the ass to.
