Hi Everyone,

I'm new on here. I recently purchased a completely stock 2000 Civic Si with 150,000 miles on it and zero rust. The previous owner had fixed a burnt exhaust valve and replaced an injector. Since buying the car I've been experiencing hard starts about 75% of the time regardless of whether the engine is hot or cold. The car starts after turning over once, sometimes twice or even 5 times. It just depends on the day.

Now here's my problem. I've gone over a lot of items on the car to try and solve this issue, including taking it to a shop and speaking to a dealership mechanic and I cannot track down this problem. The following is is list of things that I've either checked or replaced.

• New Distributor (ICU included)
• New Spark Plugs
• Timing Adjusted
• (2) Seafoam Treatments
• Throttle Body Carbon Removal
• Replaced Fuel Pump with used pump
• Main Relay Checked -OK
• Fuel Filter (New from previous owner)
• New Fuel Pressure Regulator
• Engine Compression -(Good/Average)
• New Idle Air Control Valve
• Throttle Position Sensor - (Idle 0.5v-4.44v WOT)
• MAP (Visually Inspected)
• Fuel Pressure Measured -OK
• ECU Checked -OK
• PVC Valve Inspected -OK

Does anyone have any suggestions for what I should do next? I really don't want to pay a dealership to go nuts tracking it down and charging me up the you-know-what.

 

Have you had any testing done on the Crankshaft and Camshaft position sensors?

 

No I haven't. Is that something that I could figure out on my own or have a mechanic do?
