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)
