Here are the few things alldata has on the fuel system. If these don't work, shoot me a message and I will send you the PDF.The fuel supply system is a returnless design. Most of the fuel system components are located inside the fuel tank. When the ignition switch is turned to the START position and the engine is cranking, the circuit opening relay energizes the fuel pump. The fuel pump will continue to operate if the powertrain control module (PCM) receives a reference signal when the engine is started. The fuel pump operates as long as the circuit opening relay is energized by the PCM. When the circuit opening relay is de-energized, the fuel pump will stop operating. The fuel pump delivers fuel to the fuel rail at high pressure. The fuel pressure regulator, located in the fuel tank, is responsible for keeping the fuel pressure at 301-347 kPa (44-50 psi).
Yes They are...when I was replacing my engine/tranny mounts a member mentioned them. I saved a good amount of money using them over olathetoyota. I will be using them for all my OEM parts now, and I wish I would have known about them sooner. Yeah....its 100 bux i didnt want to spend, but a NEWER car will cost me $400 - $500 a month....that includes car payment, ins and gas. No way Im going to ever spend 4 -5K on repairs a year on the Vibe. so ill keep her till she blows blue smoke out the tailpipe
Jolt, is this where you describe hooking up the gauge?: viewtopic.php?t=45481#p514969jolt wrote: ↑Wed Dec 04, 2019 12:27 am
You can hook up a fuel pressure gauge to the fuel line to watch the pressure over time once the car is turned off. The problem with the Vibe is that Toyota never put a schrader valve in the fuel line so there is no place to hook up a test gauge. I have posted on here before about the setup that is needed to test the fuel pressure. If you search, you should find it. The adapter required for this is no longer made but you may find one on ebay.
