Why is the PCM not working on the coil pack?
Why is the PCM not working on the coil pack?
PCM (Powertrain Control Module=Fuel Injection Computer) is not providing any of the Switching signals to the individual ignition coils within the coil pack because the crankshaft position sensor has failed. You’re starting point for the rest of your tests will be TEST 3.
Why is no spark coming out of coil pack?
CASE 1: If the test light lights up. This result lets you know that the coil pack is receiving power and that the power circuit requires no further testing. If you Ford (or Mercury) car or truck still has NO SPARK coming out of any of the spark plug wires, this could possibly due to three things: Bad spark plug wires. Bad coil pack.
How many inactive coils are in a compression spring?
Springs with open ends are considered to have virtually no inactive coil. Springs with open ends ground are considered to have about one-half inactive coil at each end.
How do you test the ignition coil pack?
Remove the spark plug wire that did not fire off spark from the ignition coil pack. Place the spark tester directly on the ignition coil tower, in place of the spark plug wire you just removed (see illustration above). Ground the spark tester with a battery jump start cable to a good engine Ground point or directly on the battery negative terminal.
What is the code for a failed coil?
Neither code is a slam dunk diagnosis for a failed coil. Instead of throwing a set of anything, let’s concentrate on cylinder #5. SWAP positions of 2 coils.
How many coils are in a coil on plug?
Coil on Plug: The Wired Differences 2011 ICAIA Fall Conference Ranken Technical College, St. Louis, MO Matt Dixon, Assistant Professor, SIUC Have you noticed 2 wire coils Have you noticed 3 wire coils?
When to replace spark plugs and coil packs?
This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed. The statements expressed above are only for informational purposes and should be independently verified.
