So I've taken off the intake manifold... Can't seem to find any short!
Could it b a relay? It's to the point now where I start the car and the fuse
blows right off the bat. At first when I found out it was the fuel injection
fuse... It would only be until I revved it then it blow. Now it's right when I
start it.

There are no relays.

If you can turn on the key, with the flat connector unplugged and nothing happens, then the problem simply lays on the other side of the plug.

Start by pulling off all the injector wires.  Meter across each injector. IIRC you should see about 14ohms across each. You could very well have a shorted one.

Report back, then we'll proceed.

So I I tried what u told me to do. I don't know if I'm doing it properly. I live
in Vancouver. If anyone wants to help. I'd be willing to pay if they can fix
this problem!! Frustrating and it's so damn hot out. But I have a parking
garage to work on. It would b greatly appreciated. Heck I'll even throw in
my gt spoiler. And cash.

And fuse blew wen the injected we're connected. To the clip. I really.
Think it'd that. Hope it'd that but none. Of that 14 ohm. Stuff came. Up. It
starts runs. But fuse blows. If I put a 20 amp fuse in. It does not blow. But
the car still runs funky. Could be something else.? :(

you will fry wires doing that. Do not operate with bigger fuse.

You must have a bad injector. Or a damaged harness. Either way, the upper
intake manifold has to come off.

Oh god, never over-amp a circuit like that. Those 20 cent
fuses are there to be sacrificed, so that you don't lose
the hundreds of bucks worth of components behind it. Take
it in if you're having troubles.

Normally I'd head over to help you out - but I'm leaving town for 6-8 months
in a couple days and don't want to leave you 1/2 done.

Might want to go to a shop that does electrical as a specialty (vs a "brake and
muffler" shop, etc). Can't really give you any names though, sorry.


(update: I'm back, and here to stay.)

Send a PM to Fire451 he is an amazing Fiero Mechanic and I think he has time to take on an extra project right now. I don't know his rates right now, but they should be pretty fair.

Sigh... I'm going to regret this, but....

I'm back in town on the 7th (in a few days). Time is VERY tight for me while
I'm back, but if you can have everything taken apart ahead of time, and have
it in a clean, lit etc area - I'll come by for a few hours.

PM me all your contact info.

First chance I'll have to come over is probably monday afternoon'ish. That'll
be weather dependant, assuming you're not in a fully enclosed shop.

Aaaaaand for anyone following along... After a 5 minute visit in person...

Problem solved. One 3/4 shorted injector (~3 ohms vs 12-14, so it would
have been trying to pull way too much current).
