Hi... Dave would I still get power at coil if the fuse was out ?
Expert:  david craig replied 12 months ago.

also when trying to start the car is it cranking but not turning over? if yes then watch your rpms while cranking. they should move up a little. this is to comfirm the crank sensor and wiring to it being good

How about ground.... k will get back to you

When cranking engine... the rpm does not move.
Expert:  david craig replied 12 months ago.

if the rpms do not move at all. you have to suspect the crank sensor. make sure the crank sensor has a good ground, also make sure the main battery ground is clean and tight on both the battery and engine block
