hey all i am working on a 99 express 4.3l i have no spark at all. the coil, ign module, crank sensor, plugs, wires, cap, rotor, module in the distributor, and the pcm have all been replaced. any help would be great thanks. oh i also can't get my test light to light up on the pink wire with black stripe to the distributor. i have tried with power on and while cranking. someone PLEASE help fast.

 

Check your fuses. You need to find out why your distributor isn't getting power.

 

all fuses already checked, relays checked. i'm at a loss here i have checked everything i can think of.

 

well ur pink wire to ur ign. module should have 5volts. it gets it's voltage from ecm 1 fuse in the underhood fuse block. check splice pack 132 to see if u have a broken wire there. cuz that's what splices into the pink wire that goes to ur ign. module
