no spark

[missing link]

I have a 89' GMC K2500 5.7 tbi 'My problem is engine turns but no spark to plugs, it has power to coil when key is on also while cranking also power through coil to dist.

I have a new coil and ing. mod, batt,/ Cap&rotor are fine.

Am I missing something the truck ran fine, then next time I went to start it nothing

I can't find any other sensor like a crank sensor?

any help would be great I hope I in the right forum?

thanks ML

hmmm, you say that you know you have spark to the dist right but its not getting to the plugs? The only thing there to check would be the wires, because that is the only thing between the dist and hte plugs. A sensor would not keep spark from going from the dist to the plugs. However, a bad coolant temperature sensor would keep it from starting.
