All other plug wires have spark just number 5 picks up and drops off as it pleases!! i have replace dist. cap, wires and plugs.... but none of that fixed it!! it starts sometimes and runs fine but if u shut it off and try to start it again it drops no.5... and sometimes it runs fine till you come to a stop and it does it??? i dont know what the problem is i have quite a bit of expierence as a mechanic but never incountered a problem of this nature.... i know its just the number 5 plug wire cause i when its doin it i can take it off and hold it in my hand or next to valve cover and no electric arc? but the rest will shock you try to pull them off... so its just that one.. also i took off and cleaned the rotor button with sand paper to get the corrosion off when i replaced all that and still no luck... any ideas????????

Inspect and test the crank/TDC

SOHC: its inside the distributor

DOHC on right rear of engine at camshaft end
