Question about 1996 GMC Suburban
This is a K2500 with 7.4L engine. Wife was driving & engine died. Would crank but wouldn't start. Checked for secondary spark, there is none. Battery is good, cranks over well and can hear the fuel pump running. Checked coil, tested good. Changed crankshaft position sensor on hunch that it might be bad. Didn't work, still no spark at spark plugs. Plugged in scanner and turned ignition on, but scanner won't recognize that it is plugged in. Checked fuses, all good.
Not all scanners a created equal. You need to check for trouble codes...............but it must be fixec by now.
