computer problem?

[murph22287]

ive got a 2g na, i swapped the engine to another 420a, and wouldnt start. so i started to trouble shoot and found that i dont have spark. the spark plugs are relativly new so i used my multimeter and started to measure voltage. i took the plug off the coil and found there is no power there. i went back to the relay and found there is power goin in and out of the relay. i was wondering if anybody knew if this was a problem with my computer( the one under the hood, cant remeber what that one is called at the moment) any information and tips would be helpful thx

It's called the Powertrain Control module (driver's side engine compartment) and yes it is suspect since it drives the coils (actually provides path to ground for a ms). The other suspect would be a broken/disconnected wire from the coils to the ASD relay.
