Ive owned 2 ca18de pulsars and ive got about 10 coil packs sitting in a pail in the garage, and about another 4 sitting in a car in someone's yard, not to mention the 4 that are in my engine at the moment. They go real bad. The reason why they die is because of the heat and also the ignitor. The Ignition Module is mounted on the side of the engine which is the STUPIDEST place to put it. The reason why it dies and cuts out is because of it's location. It hates heat and vibration, so where does Nissan mount it? ......see where im coming from? A dying module is hell for the coil packs too. Im working on a relocation kit for the module at the moment.slownslurious wrote:nevermind, I found that one of my spare ones is working after all... you said "I've ran through a lot of those" do you mean you have needed to replace them? Because ****... 3 of mine are stock, 1 is an aftermarket replacement, my clip only had 90,000 km on it (though it was from a '90), and since I've had it (around 6000 miles) I've had to change out the #3 and #2 coilpacks. Is this normal?
