I think its ignition but it ran GREAT all day and then I went to the saturn dealer to test a new Sky and then I drove home and it just won't fire. I turned the key and it just turns and no fire, sprayed starter fluid into the intake and still no fire, pulled a plug and turned the key and NO spark. So I am just going to replace the ignition system top to botom but I would like to know what module is the best in durability and what coil is better and what plugs run good in the cars with a little performance ignition. I was thinking of ordering through the fiero store and getting one of the high temp/high durability with a better coil with new plugs and wires. But coming august I will be putting a sbc in my vega and a big block in my 3g camaro and probly selling the fiero to buy the Sky redline because of medical reasons (my shoulder joints can't take the steering in a parking lot)so I will post on here with a price somewhere in the 1500 area with brand new brakes, top end, ignition, and working r134 ac , and bbs rims might push the price to 2000.

Put AC Delco plugs in it. R43TS I think, put a AC Delco Module in it.If you are going this far I would also change the Pick up coil in the distributor. If you want to change the coil, then I recommend the MDS Blaster coil. These have proved out very nice. Auto Zone sells the MSD coil and I am sure the Fiero store sells it also. Hope this helps

Hi, R42TS...lol. don`t ask I know--the service manual has something like R43 or R46 in it ? In either case Don has you covered ..Good Luck ..
