Blown fuse, bad connection, or ground.
yeah your right
sounds like the power transistor i just had the same deal allso could be the ECM
Yes.
i do believe it is the ecm/computer
crankshaft sensoryes because if the ecm isn't getting a signal from the sensor it doesn't know at what orientation the crankshaft is and won't let the ignition system start the engine. that's how i understand it to work
The power should come from the ecm or ecu.
It won't flash any if there aren't any to flash. It should at least flash code 12 when you use the test terminals. If it doesn't then you probably have a bad ECM. Make sure that you have power going to the ECM first. Most of the GM cars have a power wire running from the battery directly to the ECM. Make sure this is connected and the ECM fuse is good.
ECM, or Electronic Control Module, typically derives its power from the vehicle's battery and is connected to the electrical system of the vehicle. It operates using regulated voltage supplied from the battery, often 12 volts in most automotive applications. This power enables the ECM to control various functions, such as engine management and diagnostics, by processing input from various sensors throughout the vehicle.
...could be allot of reasons why you may not be getting spark, here are some: # no power to ignition coil. faulty ignition. # faulty distributer cap, rotor. # faulty ignition module. # check for start signal from ecm. ...and there is a few more.
ECM/PCM Power Relay Sense Circuit /Open
No power to the ecm. Check the fuse marked ECM in the underhood fuse panel(located in the middle top of the firewall)
With out make model and year of the car this question can not be answered.
