    Also the plastic wiring harness connector falls apart -

    The 99+ cam position sensors are a different design, and I have never seen a bad one.
    Ok, thanks for the information.

    First off, I was mixing Camshaft Position Sensor with the Crankshaft Position Sensor.
    Both sound and look almost the same. My bad!

    I am still trying to find out why the car still won't start after previous startings.
    The car worked well after replacing the Throttle unit. I must admit it runs smoother and is very responsive with the new Throttle; the cost is worth it. The car started responding with both the key and remote starter. Then it died.

    I replaced both outside temperature sensors. The dash temperature gauge started reading and the car started responding with both the key and remote starter. Then, it dies again.

    Now, trying to see if it's the Camshaft Position Sensor.

    But one of them is too expensive to purchase for a test run since am not really sure it's the culprit. $430 is too much for a test.

    Trying too get it running before winter sets in and put on my studded rims/tires.

    Thanks

    Oka, can you be more specific when you say "Then it died." and "Then, it dies again."?
    Will the car turnover and start after it dies?
    Are you using VIDA to troubleshoot your issues? If often will give you steps to follow to determine if a certain part, like the Camshaft Position Sensor, is faulty or if something else is the possible culprit. Even if you don't get a code, you can research in VIDA on Camshaft Position Sensor to get a list of symptoms for when its not operating corrrectly.

    I just saw this link. 1 through 6 of these symptoms, I have had (or noticed).

    Through all this - chasing fuel pressure and sensors, did you ever replace the MAF?

    Your symptoms sound more like MAF than anything else. "not enough fuel" was how this thread started...well, yeah...

    The ECU measures air going in by the MAF signal. It adds the amount of fuel proportional to the amount of air.

    So, low air flow reading from a bad MAF = not enough fuel going in. Erratic idle. Poor start when hot. Poor throttle response. All symptoms of a bad MAF.

    FCP Euro, IPD sell the MAF. I've even bought one on Amazon. You don't really need a genuine Volvo part, but you MUST get a genuine Bosch part. No off-shore junk.

    I just very curious. What if, the new ETM from XeMODeX is faulty; it's not impossible.
    They are not opened on the weekend to call them. Am sure VIDA would have a way to test it.

    Stop guessing about what it "might" be.

    Go back and read all the responses to your musings and questions. Hoonk (and me) have given you some simple, real, things to check in this, and other, threads.

    Until you've done that (and my money is still on cracked or improperly installed intake pipe), all the musing, wondering, and posting, won't get you any closer to a running car.

    Get a mirror, get a flashlight, and check.

    That or lack of fuel due to being out of gas or a fuel pump that's not working properly!

    (you start with the basics, and places someone has touched previously)

    In my defense about being "curious", since I don't know as much as you all so, my curiosity gets the best of me.
    In other many situations, it has resulted in solutions, from the car, computers to other areas I have sort help from forum members.

    On November 23, Sunday morning, I starter going through the posts. It's been time consuming to re-read all posts, make notes and gather information. Got them done though. Being busy with that and family dynamics does not help. Yep, so, am already on going through the posts. I have already the trouble shooting with all the information I have gotten.

    With more than a quarter tank of gas, low gas issues would be ruled out. Fuel pump, that's on my list of things to troubleshoot.
