New to Fiero ownership and this one is...interesting (Page 1/2)

Hello! I am new here and to owning Fieros. I picked this one up around a month ago. Right now it is a 2.8 auto but am planning on doing a Getrag 282 and 3800 swap. I was told a crate motor was put in (newish block and heads but 40+ year old everything else) For now I just want to get it running decent enough. I must press the gas to start and it idle hunts quite a bit. Wiring wise she's a mess

It also appears someone installed a remote start box and a kill switch. (neither of which work) It somehow runs without an IGN fuse. Otherwise its really fun to drive. Yall got any suggestions on the issues listed or just another excuse to 3800 swap it?

(more photos because I am excited about the car lol)

Thanks!

Look closer... you have no missing fuses.

See This thread.




Nathan, just so you know (for future reference)... technical questions belong in This sub-section.

Not a problem. Welcome to the forum!

That switch might go to an alarm system. I would follow the wire to see where it goes.

If the wiring is that borked, you may want to try to buy - or download - a service manual. They can save you tons of headaches.
The requirement for the "foot on the gas when starting" may be due to a non-functional cold-start injector. Does it do it all the time? Or just when the engine is cold?

Its most of the time hard to start cold, starts easier hot, still have to press the gas sometimes hot but have to always press gas and crank for a few seconds cold. Even while hot when putting into gear the engine will often (not always) die. Exhaust smells like gas (however has no cats) and sometimes has unburned fuel smoke (white smoke but smells like gas). Honestly didn’t know there was a cold start injector till now. Used to working on 3800s.

To ME, the Pontiac Fiero Service Manual of your year is 'required' if you're serious, and I prefer the printed version...
https://fieroinfo.com/manuals/

On PFF, the best tool is the "Search" button; it unlocks a huge of information and member experiences to learn on your Fiero.

The yellow paint is OEM?

Based on the wheels and exhaust, it doesn't appear to be a 88. But who knows what some PO did.
