Firing Orders & Cylinder layouts are the same. The difference is in the Ignition Coil Connections. I have included all three (3) types of Coil Systems for the Park Ave, Park Ave Ultra, and Park Ave with a Supercharger.

Need a picture of firing order on a 1991 Buick Park Avenue


Check this site I believe the black images is the coil pack firing order. I used a coil pack from a different model but had to open it up and change the firing order since the spark wires wouldn't reach for my 91 buick. You should have some knowledge about wiring before attempting that. Basically I just switched the wiring on each side inside the coil pack.https://www.google.com/search?q=buick+1991+park+avenue+firing+order&tbm=isch&tbo=u&source=univ&sa=X&ei=reisU9eSH9HioAThh4D4BQ&ved=0CC8QsAQ&biw=1440&bih=748

I think my moms 91 buick park avenue firing order is out of whack.i found the order # they go in 165432 but where is the #1 plug and the #1 position on the distibutor itself located?? thanks


The #1 plug is the first plug on the drivers side of the motor - all odd on driver and even on passenger side - the #1 position for the rotor in the distributor( if at topdead center) is around 4-5 o'clock if the distributor was a clock

I have a 1991 Park Avenue. Only four cylinders fire.


Test the compression on the two cylinders that won't fire. Make sure their plug wiring is not crossed. Check those two spark plugs after running a short time--they should be wet with fuel if not firing. Any injector that won't stop leaking should be replaced. Fuses and relays should not be responsible for just two cylinders not running. The check engine light should be on--read the computer with a scanner. An engine with two cylinders inoperative SHOULD vibrate heavily. Good luck!

1991 Buick Park Avenue Ultra dies while driving. replaced crank sensor, coil pack wiring harness. oil pressure guage flies back & forth


It is most likely a sensor. It is common in these. You may check them with an ohmmeter.
You may also test relays the same way.

A vehicle needs gas and spark to run. One of them is not getting to motor. You can check fuel pressure on test port on fuel rail for fuel.
You can pull off a spark plug, plug it back into wire, lay it on top of motor, have someone else crank, while you watch for spark, Put back in, move to next plug wire.
