If the power from the main juice wire comes and goes.it is a bad connection.often on old cars the wires do not fit tight ,the female often must be tighten down to fit the male connection better .. the electrical system in your fiero is similar to what you like in a woman a tight fit..sometimes the wire is corroded in the wire sheath and you get sometime on,, some time off ,,you can stretch the wire to check for this,you pull to see if you get the chinese finger stretch puzzle effect,check the ground wire,, the small one that comes from the battery to the frame and of course the main ground..check the connection wires to the module & pick up look inside the female connector for anything that indicates arcing or bad connection on female and male.. a bad connection leads to a faulty part .often a part is replaced and the reetablishment of a good connection is the actuall cure,then the part fails early leading to blame placed on a particular part,,When following test procedures in manuals make sure a good connection is established at all connections..The ECM is often blamed they are a reliable unit unless a "shock " has been sent thru them,battery arcing ect.. of course a bad connection can cause arcing Have you connected one spark plug to a plug wire, grounded the plug.. crank engine to determine if thier is spark?? Never arc a spark plug wire to the block on any car with electronic ignition,the newer the car the more this rule applys.. Fiero,s need GOOD ground connection
