ENGINE STALLS CONDITION-POSSIBLE CAUSE PATTERN CHART FROM DIAGNOSTIC
INTERVIEW
Conditions when the engine stalls
Possible causes
"Hard to start engine", "engine stall" sometimes
occurs due to a fault in the ignition system, intake
duct, intake manifold, exhaust system.
Pattern
1
Accessories/modifications
(Intermittent failure may occur due to modification)
The following intermittent failure may exist.
Intermittent failure of PGM-FI main relay 2
Faulty fuel supply (parameter ST FUEL TRIM)
Pattern Booming noise, vibration occurs when
deceleration, stopping, engine stalls

Delay of EGR function (parameter EGR) (only
vehicles with EGR)
Delay of VTEC, VTC system function
(parameter VTEC) (only vehicles with VTEC or
VTC)
Delay of lock up operation (parameter SLIP
RATIO OF TORQ OR START CLUTCH) (AT
vehicle)
The following intermittent failure may exist.
Pattern Engine stalls without vibrations as if
stopped by turning off the ignition switch
Intermittent failure of ignition coil relay
Intermittent failure of PGM-FI main relay 1
Intermittent failure of PGM-FI subrelay

(_____) times/day (_____) times/month
A. Warm (temp:______)
1. Weather when occurred
B. Sunny C: Cloudy D: Rainy
A. After an overnight parking, (_____) nights
B. Tends to occur about 3 hours after stopping engine
C. Parking hours irrelevant
2. Situation when occurred
3. Weather when occurred
A. Cold (temp:______)
: Filled (______) months before occurrence
Fuel when occurred

B. Used ethanol-mixed fuel
C. Gasoline additive
4. Use of specified fuel
5. How the starter motor turned
when the problem occurred
A. Starter motor turned weaker then usual
B. Spinning of starter motor irrelevant
A. Keep cranking until the engine starts
Cranking operation
B. Stop cranking after several seconds: (______) sec
A. Turn on starter motor immediately after turning the ignition
switch to ON(II)
Cranking
B. Turn on starter motor several seconds after turning the ignition
switch to ON (II) (after confirming that the check engine
indicator goes off)
A. Level
6. Ground where occurred
B. Downhill
C. Uphill
A. Full
B. Half full
Fuel level when occurred

HARD-TO START CONDITION-POSSIBLE CAUSE PATTERN CHART FROM DIAGNOSTIC
INTERVIEW
Conditions when hard-to-start
Possible causes
occurred
When in warm climate
Pattern
1
Check for the EVAP canister purge valve
Tends to occur approx 3
hours after stopping engine
When wind is blowing into the exhaust system, the exhaust gas
Weather when occurred: Windy can blow back into the combustion chamber and/or intake
manifold, causing long crank times.
Pattern
2
Weather when occurred:
Cold
If summer fuel is used during cold weather, long crank
times may occur.
Pattern
3
Fuel filled two months
before occurrence
When using fuel that is more than a couple months old
(stale fuel), the symptom may disappear with fresh fuel.
Use of non-specified fuel
When ethanol fuel or fuel other than specified is mixed,
engine stalling may occur.
Pattern
4
Ethanol mixed, use of
additive
Poor fuel quality may cause a hard-to-start condition.
When cranking, the battery turns starter motor, operates
fuel pump to boost fuel pressure to the prescribed level,
and gives power to the ignition system to start engine.
Immediately crank after
turning ignition switch to
ON (II)
Pattern
5
When the battery is weak, it takes a long time until the
fuel pump boosts fuel pressure to the prescribed level,
causing slow start in some cases.
Starter motor spins weaker
than usual
Vehicle parked on an
uphill or downhill slope
When the vehicle is parked on uphill or downhill slope, and the
fuel level is low, the fuel pump cannot pickup and pressurize
the fuel properly, causing the engine to start slowly.
Pattern
6
When fuel level is low
Check for modification in
ignition system, intake
duct, intake manifold,
exhaust system
Hard-to-start engine or engine stall may occur due to modified
ignition system, intake duct, intake manifold, exhaust system,
use of non-specified engine oil or ATF, or excessive amount of
engine oil or ATF (temporary failure may occur due to
modification)
Pattern
7
Inspect amount of
oil/fluid/gas (engine oil,
ATF, A/C refrigerant)
