Question about Pontiac Firebird
#1` can be anywhere. But usually the front of the cap. I ASSUME you mean Chevrolet 5.7 since you dont say what year Pontiac. firing order is 1 8 4 3 6 5 7 2. You may just need to line up the harmonic balcncer to TDC and then take the cap off and see where the rotor is pointing, is should be pointing forward, if not turn the engine another revolutoin intil its pointing near straight ahead. the terminal that its pointing near is #1. the order goes clockwise. #1 is drivers front. driver side is 1 3 5 7

Number one is always the front most piston on any engine. Your firing order is, 1-3-7-2-6-5-4-8 ...older engine, 1991,
The cylinder firing order was changed to 1-8-7-2-6-5-4-3, 2008., you didn't say what year your car is. Hope this helps.

Its 1342 or 1432 To guarantee correct firing order take plugs out and place your finger/thumb over the plug hole so you can feel the compression cycle.Have some one flick the key on and off slowly .As soon as No 1 has done its compression cycle the next cylinder to compress will be in the firing order.You only need to test 2 clinders to tell you which one of the two firing orders ive given you.good luck and let me know how it goes

I don't know your engine size, but the link below is a picture of the GM small block firing order with distributor.
The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
Hope this helps...
