Our P5 lately has been hard to start - taking longer to fire up. Battery is fine, the starter spins normally, but the motor just takes more cranks before firing. Seems to be progressively getting worse.
I checked the service manual and there is an 18 point flow chart to follow...
But before I just start down that path...
Maybe there is some collective wisdom that will help me pin this down.
Car has 110K miles.
plugs and air cleaner have 22K, so I doubt they are the culprit.
Here is the list of items:
Spark leakage from high-tension leads
• Vacuum leakage
• Poor fuel quality
• Starting system malfunction - (does not seem like it)
• Spark plug malfunction - (doubt it)
• Air leakage from intake-air system
• Erratic signal from CKP sensor
• Erratic signal from CMP sensor
• Air cleaner restriction - (doubt it)
• IAC valve malfunction
• PCV valve malfunction
• Inadequate fuel pressure
• Purge solenoid valve malfunction
• MAF sensor contamination
• Restriction in exhaust system - (doubt it)
• EGR valve malfunction
• Pressure regulator control (PRC) system malfunction
Any of those items more likely than the rest given age and miles?
Car is 5.5 years old, 110K miles.
These cars do not seem to have fuel filters - right?
Built into the tank?
that is what my parts guy told me.
