Expert:  Chad Farhat replied 11 months ago.

what are you missing fuel or spark or both , did you check ?

was there check engine light prior to this ?

is there a red led security light flashing or steady on on the dash while you trying to start it ?

how many miles on it ?

do you have one or 2 keys ?

Please let me know

Thank You

how about security light ?

Expert:  Chad Farhat replied 11 months ago.

If the security light is off

and we are getting fuel , you need to check for spark, those SUV are bad about crankshaft sensors being bad

Ok I am not getting a spark and the crank shafts sensor had been replaced and unused( meaning the trick had not been operated some it had been replaced)
Expert:  Chad Farhat replied 11 months ago.
