Problems

Vehicle breaks down at any time without warning

Vehicle breaks down at any time without warning. Breakdown services diagnose loss of ignition spark
DIAGNOSTIC CHECKLIST
Vehicle history of intermittent breakdown when warm is the most reliable indicator of distributor failure.

For distributor repair quotation please use form below. The entire distributor assembly (remove cap and rotor) should be dispatched to us. This should be packed in a strong cardboard box with adequate packaging. If the rotor is seized in place do not try to force off – please leave it us to remove as we have the right tools. ALSO mark position of distributor body with scratch mark before removal. This allows precise ignition timing when refitting distributor and avoids future visit to garage to have timing fine tuned.

Car starts and runs OK but cuts out when hot

There can be a history of intermittent breakdown – car starts and runs OK but cuts out when hot. Restarts OK when engine begins to cool down.

Vehicle suffers breakdown when engine warms up

All Mazda cars fitted with Mitsubishi Electric electronic distributors are prone to breakdown caused by electronic failure of distributor. We can rebuild some types but in most cases we will need to see the distributor before quoting for a rebuild. Please can you complete the quotation request form found below.

SYMPTOMS

 

Vehicle suffers breakdown when engine warms up. Usually this starts as a rare occurence but gets worse with time. Breakdown services diagnose breakdown caused by loss of spark. Vehicle usually restarts when allowed to cool down.

DIAGNOSTIC CHECKLIST

 

1) If possible, try to confirm that vehicle breakdown is due to loss of spark by connecting test spark plug as soon as possible after breakdown.
DO NOT TRY THIS IF YOU ARE NOT QUALIFIED TO CARRY OUT SUCH TESTS – MODERN IGNITION SYSTEMS HAVE SPARK VOLTAGES IN EXCESS OF 50,000 VOLTS AND CAN CAUSE FATAL ELECTRIC SHOCK – CALL IN SPECIALIST
2) If no spark, check security of all wiring associated with distributor and ignition system. Look for cracked or damaged wiring.

3) Note that SOME immobiliser systems operate by inhibiting igntion system. Immobiliser system may be suspect if there is a history of intermittent non-start rather than break down when vehicle is actually being driven.
