Pontiac Fiero - Recent Questions, Troubleshooting & Support

If you open the hood, behind the headlight assembly you will see the motor that lifts the headlight, there is a knob that you can rotate to manually to crank up the headlight until you repair it.

Before you put it up manually, turn on the headlights with the hood open and listen to see of the motor is making noise, if it is you can try a repair kit, otherwise get a replacement from the auto part store or junk yard.

Here is a handy place for Fiero parts including the headlight repair kit I mentioned:

Assuming that it's an automatic. the neutral safety switch is mounted to the top of the transmission. on a stock Fiero, if you look down into the engine bay, on the driver's side, it's right on top. You can identify it by the row of wires coming out of it.

Does the car have a distributor ? or you say DIS distributor less ignition ? If no distributor you can't adjust timing ,computer does it .

Unplug the EST wire which is brown with black tracer. Set the timing to 6 degrees advance and the re-plug the EST wire.

This could be a bad tachometer signal filter. Here is an inexpensive replacement. https://www.wc-autoparts.com/tachometer-signal-filter-camaro-firebird-fiero-corvette-gm-gmc-truck-monte-carlo/ Pretty easy to install. The OEM signal filter have resistors and capacitors that dry out and go bad after 20 years. GM placed signal filter on most of there vehicles between the mid 1970's and the early 1990's. The other item to check is the tachometer circuit board. They go bad as well. Here is an inexpensive replacement. https://www.wc-autoparts.com/1985-88-fiero-tachometer-circuit-board-ready-to-install-pre-calibrated/

The place to start is the thermastat. Sounds like it is probably stuck closed.

It probably got stuck from lack of use/lubrication. But if your lever is also stuck up it could be a function of the actual lever action. I'm assuming you tried pushing the button in to release the lever?

Step 1) Get a haynes manual if you own a fiero, VERY valuable tool

Step 2) Check the physical action of the lever, is the lever not releasing down because of the lever itself? --> frozen/rusted? something physically blocking it on the floor of the car? Or is it not releasing due to the cable tension?

It's been awhile since I looked at it, but there should be a way to take the cover off of the lever to see the cable come into the shaft from underneath the car. Follow this cable to the rear of the car where it goes to the driver side rear brake caliper, then across the car to the passenger side caliper. You can adjust the tension for the cable using the nuts on the cable.


Also, there is a spring on each caliper that is supposed to put tension on the cable when pulled, so when released the cable returns to driving position and thus releases the brakes. Are these springs missing?

Are the brakes engaged because of the e-brake being stuck?

If you are in a pinch and need to use your car and can't because the brakes are on due to a stuck e-brake, it's not smart and can be illegal in your state, but you could just cut the e-brake cable. Should be pretty easy to do where it meets the lever on the inside of the car.


Let me know if you need more help

You have to remove the speedometer drive.It has markings on it for full and add.

There's a good chance that the tachometer switch setting on the tachometer is broken. They use the same tach for different engine sizes and change the amount of cylinders with the switch. You might have to replace the tach

to make the replacement easily you can get help from service and repair manual from the given link this manual comes along with diagram and picture to help you easily and you can fix it own http://toolsnyou.com/

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus I know a website that has very good manuals online, without expiry i.e. for lifetime. www.reliable-store.com

check vacuum hoses for leaks.

For what I can see you need a tune-up - spray fuel cleaner into the throttle body directly don't let the rpm drop too much but very close to stall. The engine must be normal temp around thermostat opening. This part of the job needs to be done with the old spark plugs. - spark plugs + adjusting gap of the new ones - compression test.(no more differences between each cylinder +- 25 psi) - clean throttle body and IAC valve. Don't forget to change the fuel filter. That should solve your problems. hope it helps

did you check the ground on the body also

How much fuel pressure?

This engine is not fuel injected it is carburated.
