My 96 is real slow starting. It cranks and will start after a few seconds. I've replaced the fuel filter, had the ignition module checked, and checked the fuel pressure in the last few days (about 52 psi when idling). I replaced the plugs and wires about 6000 miles ago. Fuel pump clicks on and it's not starving for fuel once running. Runs just fine once it's going. Anyone have any thoughts on this?

I have noticed that it is taking longer to start in the mornings when it's been cooler, and the last time i drove it it never got up to normal operating temperature after about thirty minutes of driving. It stayed about 150 degrees on the gauge. I think this may have something to do with it. I also keep getting check engine lights occasionally that say that the system is running rich.
