Injection Pressure
- Perform this test if hesitation or poor acceleration exists. Operate vehicle with multipressure tester installed. The fuel injection pressure should be approximately 34.1-39.8 (2.4-2.8 kg/cm2 ).
- If low injection pressure exists, check fuel pump pressure or for clogged fuel filter. If high injection pressure exists, check fuel pressure regulator pressure or for restricted fuel return line.
