yes is gave me a pretty good shock...but from the coil to the plugs there is nuthin

cap. rotor. wires. none of the plugs get fire? probably not wires. cap, rotor.

LowboyTrucks · **Posted:** Thu Sep 20, 2007 7:02 pm

wires, cap , rotor are good...i hate to say it that ECM b/c its a 300.00 part

if you have spark going into the cap, then the distributer must distribute it somewhere right? where's it going?

well thw coil has power and its not getting to the plugs....and what sends the power fromthe coil to the plugs is the ECM RIght??

kdcgrohl · **Posted:** Thu Sep 20, 2007 7:16 pm

ecm controls the ignitor controls the coil to the distributor distributes to the plug wires.

[quote="LowboyTrucks"]i am not getting any spark to the plugs...

If the coil, cap, rotor, and wires all check OK, my guess would be either the igniter that piggybacks the coil or the signal generator inside the distributor.

im a dumbass i ment to the ignition controll module

Had any rain or high humidity or possibly washed the engine ??? could be moisture under the cap. My toyota was notorious for not having fire when it rained, small shot of wd 40 or some ether to dry it out.

that was the first thing i checked and its all clear..its some from the coil to the plugs
