will a bad ignition switch still allow the car to turn and just not start?
Expert:  Dan replied 6 months ago.

Sorry I missed that you sprayed starting fluid, yes that means its getting fuel.

How sure are you on the spark test?

Customer: replied 6 months ago.
using a noid plug tester it lit up but seemed a little weak on all 4. i didnt have the right one so i couldnt get a great test on all 4 of them. the donkey kick jolt i got when i grounded myself out by accident confirmed great power though lol

remove a coil, leave in connected, put a spark plug in it and ground the plug on the head. This is a way to test spark on the actual plug and see.

Then have someone crank the engine over.

its a single coil used to spread the 4 out

Do you not have a diagram pulled up of this year make and model as well as the engine? i was pretty sure i gave that information at the beginning

The tester i use does all that good stuff for me. i had someone turn it over while i grounde them using the light tester. same thing as a fuel injector noid light
