my friend has a 2001 Grand Am that dies when driving over 50 mph. He has changed the fuel pump and I believe the fuel injector. His engine light is on and computer tests show problems with the #3 spark plug. He seems to think that this was also changed before. Could this be his problem? or the spark plug wires?

I'd say if the computer says that that is the problem... then First check to see if the plug is clean and making a good connection, and see what happends if you replace the plug with another and see what the computer says is wrong with it (replace #1 with #3 and see if the computer says it is still #3 or if #1 is not working.... Then you might be able to deduce what is wrong with it on the spark plug issue... As far as dying, I haven't heard of one spark plug causing a car to die, but I'm not a mechanic by trade, so I wouldn't put it past that it could need all spark plugs at optimum to work at that speed. I'd see what happends after the spark plug/ wires get replaced and see if that fixes the problem.

if the sparkers are fried, you get no ignition, so sure. often this could be a sort of revolutionary failure over the years. often you may pay attention and experience that between the cylinders replace into lacking nicely formerly entire failure (this is the tough working perchance which you communicate over with). even yet it may additionally be a timing subject or a leaky electric powered ignition (sometimes the cables short out to the motor truly than sending the heartbeat right this moment to the plugs). In my journey, an electric powered bleed like this is often extra noticible in cool humid situations (like the vehicle basically undeniable has hassle beginning while temperatures are a sprint above freezing, or on foggy days, that variety of ingredient). So, in case you will replace the plugs, replace the cables and connect the distributor. Have the timing checked. i'm no longer a mechanic yet I even have had a great sort of older vehicles in my time, and one in all those ingredient you describe interior of reason uncomplicated with older vehicles.

Has he checked to electronic ignition. I had the same problem and when I changed it and replaced the wires and plugs... it went away. If it's a 6 cinlinder... the ignition is in the front of the engine. You will see the plug wires coming from it to the plugs. You might have up to 3 sets of ignitions. They are about $150.00 each. Good luck !

ask your friend if he has set the gap on the spark plug properly and to also change out the plug wires and the distributor and cap. If there is not enough spark this Could cause the enigne to die, although a car can run with one plug failing. Has he also changed the in-line fuel filter???
Let me know...
