Description

According to system inspection poor power/acceleration is caused by fuel system. The purpose of the inspection is to check fuel system.

Diagnostic Procedure
Fuel pressure Inspection
1.

IG "OFF"

2.

Install a fuel pressure gauge.

3.

Engine "ON"

4.

Check fuel pressure of the fuel pressure gauge. (Check fuel pressure at idle, accelerating and stall test)

A.

Specification : Approx. 350 kpa (3.5㎏/㎠, 49.8psi) at idle

(Fuel pressure is kept Approx. 360 kpa (3.6kg/㎠, 51.2psi) after it dropped to Approx. 300kpa(3.0kg/㎠, 42.7psi) at rapid accelerating and stall test.)

5.

Is fuel pressure normal?

YES

Fuel pressure is OK.
