    '97 Chevy S 10 Ignition.
    Checking out a Friends Truck, it has 60 PSI on the Rail, No Error Codes, All Fuses and relays good, Ground at Back of engine that has been known to cause problems is good. Going down to pick up Service Manual, any know issues, or some quick ignition tests?

    Does the truck start? If not, replace the Ignition Control Module.

    Doesn't start.
    Hey Thanks, Just got back from the Auto Store and picked up the Service Manual and Module as they don't have a Tester for that Module, They say if it doesn't work, bring it back, it was a No Brainer.
    I feel better you confirming my thought.
    Thanks Again. I don't have access to the Vehicle until tomorrow. Will let you know how it turns out, Thanks again.
    Have an Excellent New Year.

    I Installed and still no start. Manual was useless regarding this Ignition system and Coil, Secondary resistance was 7K, different pins on this coil, Did Have Power to coil with ignition on.
    Who make the most accurate Manuals? Chiltons?
    Thanks again.

    Would either of you suspect Crankshaft sensor over Camshaft sensor?
    Seems a little odd the Crankshaft sensor receives a ground after switched on?
    What is a good test for the hall sensors? Thanks again.

    Crankshaft.

    Crankshaft Position Sensor Test: Disconnect the Crankshaft Position (CKP) Sensor connector and turn the ignition ON; however, do not start the engine. Use a multimeter to check DC voltage between the sensor connector and ground. Approximately 1.5 volts should be measured. Disable the fuel system--this will enable the engine to be cranked without starting. Connect a multimeter to the CKP Sensor, with the meter set to the ACV scale. Check for voltage pulses, as you crank the engine. If there's no pulsing voltage, replace the Crankshaft Position Sensor.
