Car Will Not Start Anymore

Post by Oka » Wed Sep 25, 2019 8:34 am

Few months back, when I step harder on the gas to overtake a car, I tend to, sometimes, have a small hesitation.
The issue started getting more noticeable. Few weeks ago, it just stalled. With the ignition, the engine will turn but
won't start. Battery is ruled out.

FUEL PRESSURE READING
I connected a gauge to the rail at the valve and turned the engine (since the car would not start).
Here's my reading. What would that mean, though it's above the 40psi requirement.
I am trying to troubleshoot the car not starting anymore.
Months back, it hesitates when applying more acceleration, then, it starts stalling, then it gave up.

ECM TESTING
Plugged in the VIDA and got this (Video).
I had to edit the video to increase the audio volume level.
By the way, the Turbo Valve has a thumping sound but not loud enough to hear.
Hope I did good enough here.
Thanks again everyone for helping me here.

Check/replace the crankshaft sensor. If this gives a faulty reading, the ECU will halt the car as a safety measure (prevent fire)

Interesting. Would a bad crankshaft sensor prevent the car from starting?
Thanks.

Yes it will, I believe the fuel pump is shut down (as that safety measure)

Mmmm, very logical point. That never crossed my mind. Googled and found a sensor can be tested with a multimeter, would the testing also apply for the 2001 X/C?
Thank you.

I have no idea to be honest (I'm more of a mechanical guy as opposed to electrical). I wouldn't even bother and replace it straightaway, but that's me personally :D

If you don’t want to replace Lots of expensive parts, find the no-start thread and start 😁 there withdiagnosing the fault.
