Computer problem
1993 Plymouth Acclaim 4 cyl Front Wheel Drive Automatic 100k miles

no spark feul pump doesn't run changed hall effect sensor and PCM book says I should get 9 volts to hall effect sensor but I only get 2.8 volts if you don't get a signal from the hall effect sensor theres a relay called the automatic shut down relay shuts off fuel pump and 12 volt going to the coil It seem like the PCM is bad or something is draging down the voltage to the hall effect sensor the books I have don't have enough info I checked for shorts and the wiring from the sensor to the Pcm is good

Test the ASD relay and fuse no.11 10amp. If okay have the computer tested. The ASD relay powers the coil/injector/fuel pump
