Table 4 lists the checks required when the TECH 1
receives data from the control unit, no trouble codes are stored but the
engine does not start.
Check the following items:
· Does the
starter turn (TECH 1 Data List no. 01 BATTERY
VOLTAGE), is there fuel in the tank?
· Engage fourth
gear, push vehicle and determined whether engine is mechanically blocked (see
Service Instructions).
· Is the anti-
theft warning system / immobiliser disarmed?
· Check primary
voltage of ignition system. Ignition ON, TECH 1 Data List no. 14 SPARK ADVANCE PART 1
· Inspect spark
plugs, ignition cables, spark plug connectors and plug connections
· Fuel pump relay
does not engage. Proceed with Data List "F0" test step 12, or
TECH 1 MODE "F5" Actuator Test FUEL
PUMP REL.
· Check fuel
pressure in feed and return lines. Feed pressure: approx. 3.0 bar;
return pressure: approx. 0.3 to 1.5 bar. If these values are not
attained, the feed/return line is blocked or kinked, or the fuel pressure
regulator is defective.
· Leaky intake
manifold of throttle valve injection housing
· Catalytic
converter damaged or exhaust system blocked
· Check compression. Note: Disconnect
wiring harness plug from direct ignition system to avoid voltage peaks
thatcould destroy the control unit.
