The fuel pressure at idle will vary slightly during barometric pressure changes, but the fuel pressure at idle should always be less than the fuel pressure noted in Step 2, with the Engine OFF. 12. A rich condition may result from the fuel pressure being above 376 kPa (55 psi).

What kind of fuel injection does a Toyota 22R-E have?
The Toyota 22R-E engine has an electronic fuel injection (EFI) system and ignition system with a mechanical distributor. In 1985, the 22R engine was redesigned, many parts from the newer 22R-E (such as cylinder head, block, pistons, the timing chain, and cover, water and oil pumps) are not compatible with those from the older pre-1985 engine.
What’s the idle speed on a Toyota 22R?
The choke opens normally and the engine will fast idle at 1500 rpm after about a minute. About 5 minutes after startup it suddenly drops off and dies. It will restart immediately but the throttle has to be blipped to maintain. It will not idle on its own. Prior to the rebuild it was dirty and lacked power but it would startup and idle at 900rpm.
Why does my 22R gas engine not idle?
22R will not idle, fuel cut solenoid? Hope someone in this forum has some expertise on this one. I have an 81 pickup 22R gas engine with the Aisin carb. Carb was just rebuilt using the NAPA rebuild kit. Carb was soaked in carb cleaner and all passages were blown out with the air compressor.
