Mike,
Some troubleshooting on your part is necessary. Unplug the coil lead to the cap and stick a piece of wire up into the boot of the plug. Have someone turn the car over. You should see a bright blueish white spark coming out. If your do, the cap or rotor must be bad. (resistance check both) If not resistance check the lead, and move the wire to the output of the coil and turn the car over again. If still nothing, then you have alot that could be worng. The first place I'd check if there is juice going to the coil are the sensors that are on your transmission bell housing. These check both timing and send a signal to the coil to generate the spark pulse. There are two, and the one furthest back on the bell housing is the one that generates the pulse. If you do resistance checks and it good. then I'd say its either a bad coil or the little metal tab that is on the flywheel has come off. This is fairly common, and is a REAL pain to fix.

: : I shut car off and it won't restart. First of all is the coil suppose to have power on the pos. and negative terminals when the ignition is on? There is power comming out of the coil's end when ignition is on. I checked cap and rotor, they seem to be fine but no spark out of the wires.

: : Need help on what to look for,also fuel pump is pumping just no spark.

: : Thanks in advance!!!!!!!!
