What to do if your ignition system has no spark?
• When troubleshooting any electronic ignition system for no spark, follow these steps to help pinpoint the exact cause of the problem: • Step 1 • Turn the ignition on (engine off) and, using either a voltmeter or a test light, test for battery voltage available at the positive terminal of the ignition coil.
How to test no spark no start test?
No spark from all of the Coil-On-Plug Ignition Coils. No fuel injector pulses from the fuel injector connectors as tested using a Noid Light. P0335: No Crank Sensor Signal Detected. P0336: Inconsistent Crank Sensor Signal Detected.
Is there a spark from the fuel injector?
No spark from all of the Coil-On-Plug Ignition Coils. No fuel injector pulses from the fuel injector connectors as tested using a Noid Light.
What causes no injector pulse when engine is craking?
When these fuses blow, the system they support stops working, and the engine stops running. As a result, there is no injector pulse while craking.
What to do when your engine has no spark?
Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.

Why is there no spark in my ignition?
An ignition module requires some type of external input in order to activate. If your vehicle stalls unexpectedly during operation and will not start again, it is likely because of loose or corroded electrical connections in the ignition module. In this case, check the switch, clean oxidized terminals, and replace broken wires if necessary.
What causes no power to fuel injectors?
The most important signals that determine the accuracy of a signal coming out of ECU to injectors are crankshaft position sensor and camshaft position sensor, so to test a bad injector, you have to check the voltage on the injector when the ignition key is turned on: NO VOLTAGE? , so what causes no power to fuel injectors?
