A.
Cold engine does not start or starts poorly
|
1. Defective fuse 13, 21, 25, 27 or 28
2. Faulty fuel pump relay 3. The fuel pump does not supply fuel or does not supply enough fuel 4. Faulty fuel pressure regulator 5. Faulty idle speed stabilization valve 6. Faulty control unit 7. There is no signal from the sensor about the number of engine revolutions 8. Additional air enters the engine |
Replace
Check and replace if necessary Check for gasoline in the fuel tank Check the fuel pump, measure the amount of incoming fuel Measure the pressure in the workshop Check Check in the workshop Check the entire length of the wire Check all hoses |
B. Warm engine does not start or starts poorly | 1. Defect in the vacuum hose to the fuel pressure regulator
2. See A 1-4, 6 and 7 3. Leaky injection valves 4. Faulty coolant temperature sensor |
Check the hose

C. Engine starts, but soon stalls again | 1. See A 1 and 5
2. See in 1 3. The value of CO does not correspond to the norm 4. Defect in the air mass meter (MPI) or in the suction temperature sensor air or in the intake manifold pressure sensor (MPFI) 5. Faulty throttle potentiometer |

E. Warm engine shaking at idle | 1. See A 4 and 5
2. See C 3 |

|
G. Engine runs intermittently | 1. Clogged fuel filter
2. See A 3 and 5 3. See B 3 4. See C 3 and 4 |
Replace filter |
N. Engine runs intermittently, shuts down | Uneven fuel supply by the fuel pump | Measure the amount of fuel supplied |
I. Insufficient engine power | 1. See A 3,4 and 8
2. See C 3 and 5 3. Throttle does not move to full throttle |
Adjust throttle cable |
J. Engine backfires into intake manifold |
1. See A 4
2. See C 3 |
|
K. Fuel consumption too high | 1. See B 4
2. See C 3 |
