i have a 90 talon tsi awd. i just replaced. the engine and got everything back together. went to start it and it cranks over, but has no spark. i tried changing the coil pack and that doesnt seem to help.

also when i crank it. it keeps cranking. when i pull the key out it keeps cranking on its own for about ten seconds and then quits. i cannot figure out what is the f*ing deal.

anything helps.
