i bought a pontiac fiero 1984 2.5l v4 4 speed manual.The car has been running great for the past 4 months, but then yesterday i go to heat up the car and it turn on. But when i turned on the ac for a bit the car stalled and doesnt want to turn on. I turn the key and nothing happens like if it where dead the dash lights doesnt work neither the tack. I cant even roll up my window. All the accesories that work when you turn the key dont work. My headlights do work so there is electricity.Ive tryed putting a diffrent battery, jumpstarting, ans have checked fuses, but other than that i dont know what to do...PLEASE HELP ITS MY DAILY DRIVER!!!!

Check your fusible links, only thing I can think of, but I don't have any experience with '84.

Yeah ive tried that..car just acts dead its weird it was working fine earlier...and thanks for the reply im new to the forum and i dont have much experience with fieros...

Check the fusable links that come off of the battery post on the starter. One supplies power to the lights, the other to the fuse box.....

Just finished changing the ignition switch and nothing car still the same i will be checking my grounds tomorrow maybe just maybe..

you cant always tell the links are bad by looking at them. Test the line and make sure you are getting 12v

So i was checking the lines and it seems like the links have been burned before so the previous owner took tge links off and just soldered the wires together but now the wires seem tk have acid on them will that be my problem? And where could i buy the links?

You might just have a bad battery connection, bad battery, or bad battery cables.

Fusible links will be available at any auto parts store - just tell them the car details.

If the links were removed, the wires might have burned up internally with this problem. You will have to trace the wires with the removed links back to where they go and test them for an open or high resistance or just replace the wires, add links later after you find the problem.

do not add links until you fix this problem first!

Electrical Connections have to be free from all rust & corrosion.

And......Do not drive the car without fusable links! They were put there to protect the wiring and components.

So I changed out the wires and added links and still nothing. Do yall think the ignition module would cause this problem?

At this point it sounds like a simple bad connection. Maybe unplug, wiggle, & plug back in the connectors going to the steering column...

It okay ill look into that. What i did notice was that the connection on the wire harness thats located on the firewall has dirt and stuff on it. Im going to clean it hopefuly thats it its getting really annoying. Should have bought the 88.

Same thing could happen to an 88. Someone else on the forum recently had a loose connection at the ignition switch that caused similar problems

Okay my mechanic made the car turn on by hotwiring it to make sure it worked. But we are still in search of the wire we have found out that the ignition switch is not recieving any power. And also is there any hidden relays or fuses? Or common places that the power wires might come in lose contact?

The wire to the ignition switch may need to me replaced it may have fried.
