sounds like an auto shop job. Are we convinced this is the issue? Not the starter? Fuel pump/filter?
Expert:  Chad Farhat replied 2 months ago.

absolutely not .

1- this car comes to my shop

i would check for fuel & spark and see what i m missing & based & what i find i will check

check all fuses , check fuel pressuer, fuel pump relay , check ckp sensors, etc...

so yes i think it is a better for a shop to run the diagnostic and see what is missing and why it want start .

its better than throwing parts at it and we will be guessing at this time

ckp is common issue but that dont apply on ever situation .

Let me know if you need anything else on it , just reply back here & we can continue.

if you are good , Please Kindly rate me.
