1989 cavalier z24 no spark to one plug, changed plugs, wires, and one coil pack still no fire.
i changed my crank shaft sencor and my car now runs like new it is a fairly cheep part and is located on the back of the block frome the underside if that doesent solve your problem it may be your coilpack modual whitch can get quite expencive (around the $150 mark ) so i would try the crank shaft sencor first to find it clime under your car so you can see the back of the block there will be a wire coming from the pasenger side of the engine that plugs into what lookes almost like a temp sencor. thats it . one little nut holds it in change it out and give it a try and have fun
1989 cavalier had no spark to one plug now won't start at all no spark at all ignition module?
My 1989 Z24 2.8 has number 3 cylinder at the back not firing all the time and I pulled the plug and it's wet with gas. Weak spark and under load it cuts in and out as I let off the gas. Changed the coil pack platinum plugs and the wires! Still a problem.
