For some reason I can't seem to paste a picture but maybe this will help you. Your firing order is 1 6 5 4 3 2 going in a clockwise rotation. Your number 1 3 & 5 cylinders are the front was closest to the front of the car and the rear cylinders are number 2 4 & 6. Numbers 1 & 2 will be closest to the passenger side of the vehicle (the front of the engine). The number 1 spot on your distributer cap if you are looking at it from the front of the vehicle is at about the 1 o clock position. I can send you a diagram picture of it is need be. Just email me at [email protected] with your make model and year and I will be happy to send it to you. I hope this helped and good luck.

you can have the module off its bracket and take it to auto zone and have it tested. If they are bad than I would find a way to retrieve the codes from the computer. You can get a manual from auto zone or orielly that shows you how to retrieve the codes since it is not obd 2. Your problem could be crank sensor, but you need to get the codes. Hope this helps.

What you can do is go to a salvage yard and pull one off a used vehicle.Sometimes it`s hard to find old parts but if you can find a good salvage yard that still has older vehicles it can be very rewarding.I do this a lot when I work on older vehicles and can`t get parts for them.You can try calling a few parts stores just in case they might have one before you go out to the salvage yard.Hope this helps.Good luck.

i have one with the exact same problem with it. i put a new steering colum and fuel pump in it and it is still doing it. and not it wont even start. but it will craink, but nothing will light up. if you find out what is wrong with it let me know at [email protected] thanks sam

No, you do not need to remove the torque axle bolt to replace the serpentine belt on your 1995 Buick Riviera Supercharged Series 1. However, you may need to use a serpentine belt tool to relieve tension on the belt before you can remove it.

Have you tried looking at EBay? I did a quick search and found this. Not sure if this is what you are looking at but certainly there would be a matching pigtail. Otherwise a junkyard (call before you go) and you can probably get one from another GM car. Full size gm chassis with the same engine
