I have a 2006 Etec 150 and it has developed the problem of taking several cranks on a cold start. Sometimes is takes 15 cranks to get started. I have changed the battery to 1000 MCA, completed a compression test and all cylinders are good at roughly 115 psi, changed plugs and properly indexed. Also have taken to the dealer twice and have not received any codes on the computer. I have use 89 gas and have treated with seafoam as recommended by the dealer because he said that he thinks it's a fuel problem. Once the engine start it runs great all day long. I can shut on and off with one crank after the engine warms up. Any suggestions?
Most of the time we find that some maintenance steps have been missed or overlooked when an E-TEC is hard to start. Your motor is 9 years old and should have had at least 3 complete dealer servicings since new as they are required every 3 years or 300 hours - whichever comes first. The engine computer and the diagnostic software are not the final word on finding something wrong. They only are one of many tools a technician needs to troubleshoot a motor. The computer diagnostics only test certain electrical items and keeps an engine history. It does not check much more than that.
Some things for the technician to inspect :
Correct and indexed spark plugs - gapped .028" and in good shape
Compression or better yet a leak-down test
Remove and clean or replace the exhaust pressure sensor tube and restrictor orifice
A fuel pressure test and replacement of the Vapor Separator Filter screen
Check cranking rpm and starter voltage while cranking
Check cylinder head idle temperatures - if not warming up enough, carbon will form in the motor.
Test temperature sensors, air and engine, for proper reading before engine startup
Make sure the latest software is programmed into the EMM
Comply with all service bulletins that may apply to the engine
Your motor is likely a 2007 model as that was the first year for the 150 HP E-TEC even though production started in 2006 - just like today, you can already buy a 2017 car and it is still 2016. What is your engine model number?

Just an update to my cold starting issue. I did the following things listed below:
Thanks for the advise Bill. It took me while but I am glad the issue is resolved.
Glad to hear that you got it fixed. I feel bad for you as it should have had 3 complete dealer services already as it is over 9 years old and each service is supposed to include any software updates that may apply at that time.
