Question about 1991 Chevrolet Camaro
New fuel pump, fuel injectors, new alternator, new battery... Heard it could be a vacuum leak and I found four loose hoses... not sure how to connect all vacuum hoses... Was running after I got it smogged... They reset computer and it ran for a day then stalled. Runs for a little but like it misfires until it dies
CHECK SPARK PLUGS AND TIMING ~~( ALSO TUNE UP DISTRIBUTOR CAP, EGR, O2 SENSOR) , VACUUM WILL CAUSE LOOPS BUT WONT CUT CAR OFF

Check your egr vavle. i had this problem with my old cavalier and it was as easy as removing it and cleaning it. It's probably plugged up with carbon

I would check to be on the safe side the fuel filter is going in the right direction. The arrow is pointing towards the engine away from the fuel tank, Then you need to make sure the fuel pump wiring connections are good contact and did not come loose when driving.

I believe it is electrical, and someone,
1.Has tried to bypass the use of the correct ignition key,
2.Or a fusible link for the starter is blown.
Does the ignition key have a chip on the side of it? The 1990 Camaro uses an ignition key with a resistor on the side of it. (Chip)
I had a guy install a radio, cut many wires, then wired it up wrong.
I found fusible links in the engine compartment that were blown, and wires that weren't hooked up correctly.
Took a couple of days, plus the wiring schematic for the engine compartment, and interior, to figure out what he had done!
My suggestion would be to find out if the ignition key fits THAT car first. (Dealer info)
Find out if it's the correct steering column.
Then look under the engine compartment to check out the starter wiring. You'll need 1990 Camaro wiring diagrams.
The prior owner bypassed the ignition switch with that push button momentary switch, because either/or a fusible link has melted through, or it is the wrong ignition key. (And maybe a different steering column complete with key switch!)
The 'Chip' on the key is a resistor, and THE correct resistance is needed to bypass the theft deterrent system.
