Hi... Dave would I still get power at coil if the fuse was out ?
Expert:  david craig replied 5 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

When cranking engine... the rpm does not move.
Expert:  david craig replied 5 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
