Hi all,

Just wanted to give a general update
since last time when the issue fixed itself, it has not come back yet. I did not do any additional work other than what I explained a few weeks back on this forum.
Thanks again to everyone how helped and gave me suggestions. I will let you know if anything changes

Thanks
Asghar

Hi all,

The issue just came back, now it is not starting when getting a jump from another vehicle either, it kind of seems like the crank sensor. It started back on once the car cooled down

No spark as you say when cranking.
Each ign. coil needs power and ground to energized.

Igniter (coil) power check
--- Disconnect 1 ign coil connector (any accessible one)
--- Key ON posistion
--- White wire w/ a RED tracer should have POWER

Now for ground check for the igniter (coil)
Each coil shares the same ground.
--- Key OFF
--- Same connector
--- White wire w/ BLACK tracer
--- Should have continuity to ground

Let me know what your results are.

Were you able to do these checks?

Read the following article on a bad crank sensor and what causes them to go bad.

​​​​​​https://scanneranswers.com/diagnosin...sition-sensor/

This is what a working crank signal (ckp) look like

Nad1370, I am waiting on a multimeter to measure that

A new finding, I tried connecting 2 different OBDII readers and both said they can't connect to the vehicle. this was when the car wouldn't start. does this mean anything

Audiqv8, Thank you for the link, I will read it now

Check your 7.5amp OBD fuse

Was the key in the 'ON" position when you connect the OBDII? Did the OBDII work when the car started?
