This is a car my son normally drives, he related that he has gotten the "urgent service" message a few times related to full throttle and accompanied by no brake boost (a secondary issue I think.)

He dropped the car off to me for evaluation. I was able to recreate the issue very easily. I ...

Just a brief update to say thanks for the guidance on this problem. Ordered the starter noted in the thread, it arrived very quickly. We got it installed yesterday with only the typical issue with contorting one self to blindly attach and clamp the intake hose to the throttle body and the car fired ...

My car is a 2001 S60 T5, so probably less complicated by some factor. I am currently working through a starting issue as well, not likely related to what your are dealing with, but understand the frustration. My experience has been that most of the error messages are likely to lead to chasing your ...

Do we know if no input from the crank shaft sensor kills spark and fuel?

Yes. An old starter creates a lot of interference in CPS wires that are routed nearby. Either replace the starter, or reroute the wires (put a new ones, as old ones are hidden in the loom).


Ah, now I get it, never ...

Run your own crankshaft sensor's wires to ECM as far away from the starter as possible. Or replace the starter, they are cheap. I have this one: https://www.amazon.com/gp/product/B007Y85MFE


Thanks, started is good, turns the motor over well at all times. Sounds like tracing those wires is a ...

are the plugs sparking during no start cranking?
do the injectors click when it won't start?
That would coincide with your suspicion of the crank sensor circuitry.
VIDA would really help.


Thanks, that is good basic trouble shooting, something I have overlooked. Do we know if no input from the ...

To date I have combed back through all the “difficult starting” threads and have done all the checks and parts replacements that I can think of to no avail, so looking for any new thoughts and bright ideas.

Car History: 2001 S60 T5, 5 Speed manual transmission, 175,000 miles. I bought it with ...

I have attached a few more photos.

Engine does turn over easily by hand, spark plugs look good and are Volvo branded.

Let me know if there is other information you need.

Well, a disappointing outcome to the test. I set up a leak down test. I am no expert on running this test. Even when I think I am at top dead center right on, when I apply the air pressure it always makes the engine turn. While holding the crank in place while applying the air I could develop ...

I can only make a guess at the mileage. The motor came with a car that I purchased. That car was taken off the road in 2013. The owner bought the motor intending to replace the motor in that car. He said the motor was in a 2006 that was rear ended and totaled. That car would have been on the road ...
