Pontiac firebird ssa: Just bought a 1989 firebird with a 2.8

This answer was rated:

Just bought a 1989 firebird with a 2.8 ltr and.was getting no spark so I replace the coil and I still have no spark .is there a main fuse possibly ?
The diagram shows that the ignition coil receives power from the ignition switch. The ignition switch receives its power from a fusible link. This same fusible link powers the blower motor on HI. So, if the blower works on high then the fusible link that powers the ignition coil is good.

I suggest we work a little on diagnosing the no spark beginning at the coil and working our way backwards from there.

Do you have a voltage meter or test light?

Do you have 12V to the pink wire going to the coil with the key on?

I am just buying tI just checked that blower motor and it works on high. I tapped into the pink coil wire and held the other and with my hand and turn it over and didn't feel anything
What did you use to test the pink wire?

It should have 11-15V to it.

I don't have a tester with me , I just held that wire that I tapped into the coil wire with my bare hand and did not feel anything .I would think I would have felt voltage right ?
You wont feel 12V it is too low of a voltage to feel. Unlike a spark plug wire which is a minimum of 30,000 Volts.

You will need a test light or voltage meter to measure it.
