ask title stated what line to i pull out to check if its wokring my car crank but dont turn over

 

Crack that 17mm loose, but watch your eyes just in case you are getting proper fuel pressure.

If no fuel when 17mm is relieved, try to cycle the ingition to the "on" position with the 17mm loose. If you get out and see fuel your pump is working, from there you need a Fuel Pressure gauge to check if you are getting the proper amount of fuel.

 

check for spark first .... more than likely distributor ..... its not a gm ....lol

 

Turn the key to II and have someone listen to the pump to see if it primes. If not dont bother with the fuel filter.
