Title: 84 fiero won't start
Post by: Cdepoy84 on December 20, 2021, 10:37:14 am
My fiero won't start, I've put a new battery, positive connection cable, and new starter but it still won't crank. It will power everything else however when I go to crank it everything dies out. Does anyone have any ideas

Standard transmission or automatic? If standard, it could be the clutch safety switch.
But what do you mean by "everything dies out"? Maybe one of your battery connections is loose.

Check both connections at the battery.
Check your connection where the big red positive wire is bolted to the starter.
Check the connection where the big battery ground wire connects to the block or head. 
While you're checking the positive wire, check the fusible links. On an 84, they're connected to the big starter lug, along with the battery wire.
There also should be a small ground wire that goes from the battery, down to the frame/shock tower.
It's also possible that one or the other of your battery cables/connectors is bad. Maybe corroded where the connectors attach.
Those are all the first things to check.

If you have to get under the car, make sure it's in park or neutral and the wheels are chocked. There was a guy, up north, a few months back, who got crushed under his Fiero.

Every time I've had that problem, it's the cable at the battery.  It seems that today's battery terminals don't have threads that come all the way out to the surface where the cable contacts.  I've had to purchase the battery screw posts that are designed for multiple cable hookups.  The bolts are long enough to engage the threads deep inside the side terminals.
