I finally decided to resume work on the Volvo. Having tried all of the recommendations given in the past, I have a single question at this point in time. There are two ambient sensors on the car. One is installed at the front lower grill on the driver's side, and the other installed on the plastic c...

Hello all, Got back to Florida yesterday. After a pleasurable trip, I will now continue to deal with my cold start issue some time next week. Right now I am taking a vacation from my vacation. THINGS TO DO: some yard maintenance work on my Jaguar restoration service my other vehicles pay my bills th...

@ Abscate: I am taking a break from the Volvo for a couple of weeks. Heading down to the homeland next Tuesday. I will resume troubleshooting when I return.

@ abscate: Yes, after replacing the CVVT solenoid, I cleared the code and have put a couple hundred miles on the car with no returning CEL. As a matter of fact I have put about 700 miles on the car since I did the head. Car works great except for the issue we are discussing. Your suggestion is somet...

Update: Test performed: Temp 58 degrees, Key 'ON' fuel pressure immediately at 55 psi. Pump good Crank engine, No start. Introduced starter fluid, car started immediately. My reasoning > No cold start enrichment. Went to Volvo and purchased an OEM CTS. My reasoning > ECM needs correct input from CTS...

Since I did the cylinder head about a month ago, I have changed the oil twice. first time to get rid of any residual coolant in the block,and then a second time about three weeks ago. I used 10W30 and a cartridge from the dealer.

I understand what you are saying. Assuming that I use starter fluid, the vehicle will start, so that rules out the ignition system. What's the difference between using starter fluid and using gasoline if the car will start using either of the two. How will the starter fluid help me to isolate the pr...

I introduced some fuel into the intake and cranked the engine and it did the same thing. Thinking that I had too much fuel, I disconnected all 5 of the fuel injectors and the car started right away. After the introduced fuel was consumed, I reconnected the injectors and the car started up right away...

Update: Engine is taking about 1 -2 minutes of cranking to start. At the rate I am going I will have to replace my starter soon. Once the car starts, it will start normally for the rest of the day. It is the first start of the day that is killing me. Here is what I have done so far to try and narrow...

@Ozark lee.... I did perform the fuel pump leak down test. Left it pressurized at for over an hour and lost just a couple psi So I think its good Mid 40s.
