P1200b code 97 malibu


I would suggest that the cam sensor doesnt do much and the crank is the predominant one here. P1200b is the injector circuit. Try checking all wires to injectors and the harness connectors. If it jumped it's timing perhaps or the crank sensor was broken or bad it will not fire or fire erronously.

Bad ground wire on injector


Hello: Depending on what year, model cadillac, the ECM (engine control module) or the PCM (powertrain control module) provides the ground to fire the injector. To check to see if it is firing you need a node light to connect to the injector and attempt to start the engine and see if the node light illuminates. Using a test light is not recommend as it may require to many amps and destroy the driver in the control module.

I have no injector pusle on a 1997 chevy blazer ,my question is does it get its injector pulse from the control module?


The ECM or electronic control module does fire the injectors, however, the injector pulse that the control module uses to fire the injectors is generated from the igniton module inside of the distributor and then the injector pulse is processed through the control module.

Most likely the ignition module that is inside of the distributor is faulty, or there is a damaged or grounded wire between the control module and the control unit. If there is no problem to be found with the ignition module inside of the distributor or with the wiring between the control module and the ignition module inside of the distributor, then the problem will be with the electronic control module itself. Also, check all of the fuses to the ECM.

Let me know if you require any further assistance.

Only one injector is firing


There is a sensor on the camshaft that send the signal to the sparks plugs and to the injectors in order to have spark and fuel in the right time. Check first this one. Is still dont have the right fuel on time, check your computer. If not the computer, not the sensor, then check your engine timing.
