I had a similar problem with my 87 and 88 GT's. I replaced the ENTIRE ignition system from the distributor out to the spark plugs. It turned out that the problem was the cold start injector sensor was bad AND the plastic connector was brittle and falling apart. I would suggest checking your cold start injector sensor as well as your temp fan switch. Both of these sensors are located on the top right hand side of the engine right behind the thermostat housing and under all of those plastic vacum hoses...if you have the V6 engine. You could even start by pressing the connector down on the sensor just to make sure that it didn't come lose. That actually worked for me but after the car started I decied to replace them anyway.
I would also check the ignition module. These commonly fail in V6 Fiero's. They are bolted to the top of the distributor right under the cap.
Hope this helps to solver your problem. Fiero's Rock! I've got 5 of them.

Hi, My 86 Fiero GT started and ran for a few blocks and then stalled. It turns over, but then it just shuts down. My battery is new, and I checked the cables. It may also have rod knock or spark knock. ...


possibly a bad fuel pump, check there first. Have someone spray an ether based aerosol cleaner into air intake while starting, if car runs while spraying then your fuel pump is bad and needs to be replaced.

My 86 fiero wont start ? i check the coil no sprak ,, went and got another one replace it the car start onecs then wont start again it cranks but no spark at all ... can some one help me plz


Could be a number of things. Check the distributor cap and rotor, check spark plug wires, check the actual spark plugs for worn or missing electrodes.

It also could be your distributor, but that needs to be checked out in a shop.

Have you checked the fuel? To start a car, it needs fuel + spark. Fuel pump working? Squirt starting fluid in the intake while trying to start it. If it starts for a second and dies, your problem is fuel delivery. If it doesnt, it's probably electrical.

Too much fuel pumped into the carb. What to do?...adjust?...set?


The idle air control valve may be at fault, also the throttle position sensor may be telling the engine th wrong information and sending too much fuel, a couple other ideas come to mind but I not an expert. A faulty injector is one of them.....I another idea that may help as well: Vacuum Leak: The ECM will try to compensate for leaks up to a certain size. This will cause the ECM to compensate and possible send too much fuel to the engine...???? Good Luck
