First... get that 30 amp fuse out of there... the reason it has a 15 amp fuse is that something on that circuit can't handle any more than 15 amps and you are going to blow it.. if it isn't already and causing the fault to begin with..
Second, most likely, something is grounding out or pullin too much current through that circuit. if its an 86-88, you can get the electrical wiring diagrams off the tech manual pdf's on teamfc3s.com. find that fuse, and what is hooked up to it, and look for bare wires, crossed wires, burnt wires or smoked parts...
Did you hook anything up recently before the problem started..... new amps, stereo, foglights??????
Third.. YEP, gotta take the uim off to get the pulsation damper off.. its on the primary rail down on top of the engine block.
while you have that off, you might want to replace all the vaccume lines that are down there.. like the oil injector vaccume spider lines and all that junk... they probably are hard as plastic by now.

I'll second that. I wish I had more help to offer, but YoD hit it right on the head. -John

OK...... then YOUR BUDDY was monkey'n around and got something crossed or grounded wrong.
Finding an electrical problem on a unfamiliar car. especially when YOU didn't cause it, can be a real pain in the ****, bud.
I know there are some other dudes in here from Washington, hopefully one of them will come and eyeball it for ya.
Is that fuse in the box under the dash, or out by the strut tower??

LOL...... i take it this is your first 7????? ooooohhhh boy!!!
I'm really not trying to be rude here... but you had better get reeeeeaaallly used to figuring out one little problem after another!!!
Your 67 camaro's electrical system is 100 times simpler that the one on that 7!! and the vaccume system, lets not even go there... yet!!!
I'll break out the diagram tonight and see if i can tell ya what's on that fuse to look for...

All right, this is on a 86-88 anyway:
1) disconnect the small 2-pin plug at the back of the alternator
2) disconnect the circuit opening relay plug, located below the steering column, can't miss it, it's the only relay in that immediate area
3) put a 15 Amp fuse back in, see if it blows...if it does, your main relay is bad, it's the big one just forward of the clutch master cylinder, driver's side on the firewall
4) if it doesn't blow, reconnect the alt back plug...if it blows now, your voltage regulator inside the alt is bad
5) if it still doesn't blow, you've got it narrowed down to the Air flow meter and the fuel pump (disconnect either for further troubleshooting...good luck

you know what, if the car has been sitting start with the fuel pump first- diconnect the plug behind the carpet at the rear left side strut tower, 9" below the speaker position...pull the plug apart, insert a new 15A fuse, and go for it...Key must be on to power the circuit....if it blows with no key, you really got problems...

and would that also cause my instruments to only work when the car is moving or in 5 and reverse? and i am going to test all this in about 30 min after i get some 15 amp fuses caue i'm out of those but after testing it i put a 20 in there min ago and that didn't pop this time and thats only 5 amps higher so i don't know and i tested the fuelpump thing with that and it didn't pop

look under your dash, follow the steering column down, on the right side of the column will be a "box", with maybe 6 wires connecting from the bottom. the middle wire will be black/ with white stripe, couple of blue ones too, if I remember correctly. think it's also got some yellow plastic on it somewhere...

that fuse shouldn't have anything to do with your instruments...sounds like you got some some wires crossed somewhere...at least you know the 5th gear switch is working in the tranny!

EVERY gauge on the cluster, huh? might be something easy like a loose connection (black/yellow wire at the back of the cluster), or it might be some weird intermittent short somewhere...make sure the 7.5A "meter" fuse is in the fuse box nice & tight...
