I'm still driving a 99. Had to replace coil pack. Purchased an aftermarket coil and truck ran like crap. Checking the new coil pack with a multi-meter I saw it was out of Ford spec. out the box. Replaced with Motorcraft coil and it ran perfect. Just my opinion, but it appears Ford engines are finicky when it comes to coil specs.
The car has a new oem coilpack and spark plugs and cps (crank positioning sensor) car now gets very low spark not enough to start what do i do
Disconnect the electrical connection from the coil pack. With ignition on, check for battery voltage to the coil. With the clip pointed up on the plug, the positive should be the one on the left. If voltage is present, check the primary resistance of the coil. It should be between .03 and 1.0 ohms. Then check the secondary resistance. It should be 6.5 to 11.5K ohms. The resistance for the spark plug wires should be 5,000 ohms per foot. If all checks out, get a high voltage calibrated ignition tester and check each plug wire where it attaches to the plug. While someone cranks the engine notice the tester. There should be a bright and well defined and regular spark. Do the same for each plug. Videos on the net should be available to show how to.
