TROUBLE SHOOTING

NOTE: The following Trouble Shooting pro-
cedures are basic checks only. If these pro-
cedures fail to locate the fault, refer to the
System Diagnosis and Adjustments heading
for more thorough testing.

Prior to performing any of the following
operations, refer to the Service Precautions
and Procedures heading.

ENGINE WILL NOT START OR HARD TO
START
(1) Water in the fuel: Dr ain the fuel from the
system and renew the fuel filter.
(2) Fault in the power supply: Check the battery,
fusible links and fuses. Check for clean, secure con-
nections, particularly the earth connections. Check the
EG1 and fuel pump relays.
NOTE: If the fuel pump relay fails, power
will be supplied to the fuel pump via the oil
pressure switch. When starting the engine,


Check that the MAP sensor hose is not blocked or split
and ensure that all electrical connections are clean and
secure.
