JUST HAPPEND 10 min ago
GMC SUBURBAN K-2500, 1996 - 5.7 Vortec.
Here we go...........sitting on a parkinglot waiting for my lovley wife......engine idling nice........
all of the sudden , motor just stops running...........?! @##$%^@ i think and go check everything.
OK,,i thought its the fuelpump relay.....NO,,,,,,,pump works.......now i go and check the coil, pulled the coil wire off and cranked the engine .........NO spark !!!!!!!!
So, here is my question !!!!
If i replace the coil in the morning, will i be able to drive the truck back home ???????
Or could it be something else ??? Maybe a power source feeding the coil or so ???
I did check all the fuses aswell and they are ok .

The coil is triggered by the control module. Check for loose wires between the coil and distributor. Pull the distributor cap and look for red dust. The red dust causes arcing inside the distributor and can cause premature failure of the control module. Some parts stores can test the coil and module.

Could also be the coil wire itself, speaking from experience. 1997 Suburban 350, just driving along and motor quit, turned out to be coil wire.Adam

Just for **** s and gillggles disconnect the tach connector from the cap it might be grounding out somewhere. Also check if your getting 12 volts at the coil.
