Question about 1998 Pontiac Grand Prix
I recently had my 1998 grand prix se, 3.1 v6 engine replaced with another 3.1 v6 engine. the engine runs fine, the problem is the rpm cluster will not work, it engages when I first turn on the ignition and then stays down, i was told that the repairman may have connected the spark plug wire to the ignition coil wrong? Also my traction control lite on the dash board will not go off, no matter how many times I push the bottom. before the repairman replaceed the engine all of the things i describle above were working fine. what do you think?
Probably didn't connect the tacho wire to the right side of the coil for the first problem
because the engine was replaced it is possible that a sensor wire to a wheel for the traction light was damaged /disconnected

Your problem may be a faulty (shorted) ignition coil housing assembly (the white plastic cover housing the coils its bolted to the aluminum cover) change that along with the spark plug boots ( the boots are optional but I recommend it) that should get your Grand Prix running smooth. Good luck and keep me posted, be glad to help

Call dealership and find out if it's a "PMI" system. If it has to be PMI'd at the dealership, then the old instrument cluster has all the old data in it. You have to remove all of the data from the old instrument cluster and put it in the new cluster before the car will run.

this engine is turned sideways in the engine compartment. looking at the front of the engine, where belts and pulleys are mounted, the odd number cylinders are on the left, the even to the right. starting from the front of the engine, counting towards the rear, the cylinders are numbered 1, 3, 5 on the left and 2,4,6 on the right. remove the spark plug in the number one cylinder and place a peice of tissue in the hole. now crank the engine in very short bursts. as soon as you hear the engine crank, let off the key. check for the tissue to fly out of the spark plug hole. once the tissue flies out, the number one piston is up. now you need to take the cap off the coil, and see where the rotor is pointed. hold the cap over the rotor to see which terminal lines up with the rotor contactor. connect one end of the plug wire to the corresponding terminal, and the other end to the number one cylinder spark plug after it is reinstalled. from here the coil terminals are numbered in a clockwise direction. the firing order for your engine is 1-2-3-4-5-6, so you just connect one end of a plug wire to the number two terminal, and the other end to the spark plug in the number two cylinder. repeat this procedure for the remaining wires,
