The above application is prone to the timing belt teeth lifting off the belt in service due to operating the belt with insufficient tension. The following instructions have been produced to assist in the fitting of your new timing belt, giving simple hints and tips, which should help avoid problems caused by adopting an incorrect fitting / adjustment procedure. For instructions for the removal of the engine components required to gain access to the timing belt, please refer to the vehicle workshop manual. Note:- Incorrect tension of the timing belt, can lead to the teeth lifting from the belt, resulting in belt failure, and subsequent major engine damage. Special Tools Required: 1) Timing belt tension gauge, (accurately calibrated), Part No’s: either Rover KM4088 or Borroughs BT33-86F 2) Two 8mm Allen keys (for tensioner adjustment) 3) Short length of round steel bar (for flywheel timing location) Fitting Procedure: 1) Before the old timing belt is removed, the crankshaft should be rotated clockwise to align the timing mark on the crankshaft pulley with the edge of the metal bracket, which forms part of the lower timing belt cover (See I). To lock the crankshaft in this position, which is 90 degrees before top dead centre, insert a steel rod of the correct diameter into the hole on the gearbox / engine adaptor plate, positioned on the front facing lower edge of the cylinder block (See diagram B), and locate with the corresponding hole in the flywheel. The timing marks on the camshaft gears should now be aligned at the 3 o’clock position for the left hand gear, and the 9 o’clock position for the right hand gear (See II). Undo the timing belt tensioner Allen bolt and remove tensioner. The old timing belt can now be removed (See III). Check the condition of the geared teeth on the camshaft, crankshaft, and water pump drives. Check the tensioner, water pump, and idler bearings. Fit the new timing belt over the drive gears, ensuring the timing marks set at ‘I’and‘II’ have not moved. Refit the tensioner using the anti-slip washer ‘IV’ supplied with the new timing belt. The anti-slip washer should be fitted between the tensioner and the backplate, with the abrasive side facing towards the tensioner. Note: A new anti-slip washer must always be fitted. Non modified vehicles will not have the anti-slip washer fitted. Rotate the tensioner, using the Allen key drive to set the initial pre-load tension, sufficient to prevent the timing belt from slipping over the toothed drives, then tighten the Allen bolt to 45Nm.

There are many problems with the BeCM (Body Electrical Control Module) fitted to late model (from 1995) Range Rover and Discovery. Click here to see photographs of this unit. The BeCM controls virtually EVERY electrical function on the vehicle and problems within the
BeCM (or its associated fuse box) will cause mis-operation of vehicle electrical functions. When diagnosing electrical problems on vehicles fitted with BeCM, it is vital to appreciate the relationship between the BeCM and its associated electrical fuse box which is located in the engine compartment.

Technical Bulletin ROVER 1.4 K SERIES ENGINE – STARTING PROBLEM

Fault
It was reported on the helpline that a caller had fitted a second hand engine from Rover 25 1.4 MPI vehicle to a 1998 214 1.4 MPI vehicle. Upon completion of work, all wiring to the engine management system was checked and vehicle would crank over but would not start. Caller even tried fitting the original Crankshaft position sensor (CPS) from the Rover 25 vehicle but without success.
Cause
Upon inspecting the difference between the two engines, it was noted that the original Rover 214 engine was fitted with a MEMS 1.9 engine management system, and the engine from the Rover 25 was fitted with the MEMS 3 engine management system. On initial inspection the 1.4 MPI engines seemed identical, but on closer inspection the flywheels with the reluctor disk were seen to be different. It was noted that the gaps in the reference teeth were different between the two engine management systems, and this difference stopped the
engine from starting.

2006 Honda Civic Immobilizer Indicator Is Blinking Engine Won’t Start

SYMPTOM The engine does not start, and the immobilizer indicator is blinking (especially if the battery recently went dead and the engine was jump-started). PROBABLE CAUSE The immobilizer IMOES code has been erased. NOTE: This problem occurs only if all these conditions are met: • The security system is set. • The battery goes dead. • Battery power is connected to the vehicle, then disconnected in a very short period of time (milliseconds). If the vehicle meets these conditions, or if the condition is unknown, go to DIAGNOSIS. CORRECTIVE ACTION Replace the under-dash fuse/relay box (MICU). DIAGNOSIS NOTE: When the immobilizer system is not allowing the engine to start, the results vary depending on the model and how quickly the ignition key is turned. 2006 Civic 2-Door, 4-Door, Si, and GX • If you quickly turn the ignition switch from LOCK (0) to START (III), the engine starts and runs for about 1 second, then shuts off. • If you turn the ignition switch to ON (II), then pause before turning to START (III), the starter cranks, but the engine does not start. • When the ignition switch is returned to LOCK (0), the indicator blinks 10 times. 2006 Civic Hybrid • During moderate weather conditions, if you turn the ignition switch to START (III), the gauges and gauge indicators come on, but the engine does not crank. • During extremely cold conditions (about 0° F or lower) or a low IMA battery: – If you turn the ignition switch quickly from LOCK (0) to START (III), the starter motor, not the IMA motor, cranks the engine and it runs for about 1 second, then shuts off. – If you turn the ignition switch to ON (II), then pause before turning to START (III), the starter motor, not the IMA motor, cranks the engine but it does not start. • When the ignition switch is returned to LOCK (0), the indicator blinks 10 times.
