Just had used motor put in car. Motor sounds great and plenty of power.But in the morning car turns over slow. New battery recently installed in car.Have to pump throttle to get car started. After first start, car starts with no problems rest of the day. Had new sparkplugs installed and coils check.

Sounds like an injector may be leaking overnight. Does it start faster if you hold the gas pedal down?

Fuel pump is located in fuel tank... lots of information on how to do a replacement at http://www.q45.org. If you can smell gas, you might have a bad o-ring on the fuel pump. I don't know a ton about this, but I know this is a common problem.

Do it soon... before it melts your FPCU.
