Default This will blow your mind

car ran, parked it for a week and now it has no spark.
new dizzy(less than 60 miles), cap, rotor, wires,(less than 700 miles) coil,(maby 20 miles) & tfi.(maby 20 miles)
w/ key on, i got power to coil, no spark coming from coil.
i put old coil on, it worked but i had spark blowout in higher rpms so i got a blaster coil, and plugged in the old coil still didnt give it any spark, plugged old tfi in, no spark still. w/ spout out it wont start. i got power to tfi on like 3 of the connectors, if i remember right, #2, #3, and #4, #4 had .88v, i think 2 and 3 had batt voltage or close to it. the + wire to coil has .6v less than batt voltage.

what do you think is going on?

i need some help with this thing, i live near Covingtion in Louisiana, let me know if you are available, thanks!

well if spark isnt coming from the coil, the dizzy turns and sends the signal to the tfi and the tfi sends it to the coil then to the cap? or something like that.

i hope its not the dizzy, well i mean i do, easy fix, but that would be the 2nd reman dizzy, the 1st one from carquest didnt fit, the second one lasted 3 min, and i went to napa and got this one...
im going to have to do the dizzy turn thing and see if i get a on/off signal to the coil.

the stator is what ID'S each cylinder and when to fire .....the reluctor wheel that spins round and round with the dizzy is the marker for the stator to id the cylinders.....after that the signal is amplified / tranfered trough the tfi where pip is sent to ecm for output of injector and coil control......so a no spark from the coil either indicates a tfi prob or stator issue.. that's to say all fuses are intact, coil is known good and all ignition powers and grounds are present
