Up until yesterday, when I would start the car it would crank twice and start. Now ...cranks 3-4 and will only start if I step on the gas. I can hear the pump prime just like always...and once it starts it runs perfectly. Any ideas?
Does it happen right after its been running or does it have to sit for awhile first?
It happens at cold start. Once it starts it runs normally. Yesterday I tested a few things. The fuel pump primes when I turn the key into the "on" position. If I bump the starter, it primes again as it should. Once I started it, ran an errand that allowed it to get up to temp, and restarted it ...it stated normally.
I have no idea. I have had the car for about 8 weeks. It's been running nicely (still does once it starts) so the plugs, wires, and ignition have been lower on my list
That would be high on my list. It doesn't fit the sudden onset of the trouble however. Many times the front three plugs are still original. Pull the four 13 mm head bolts that hold the deck lid to the deck lid hinges and you gain enough room to get in there with a socket wrench.
Don't mess with the security torx screws on the hinges or think about unbolting the hinges from the body.

After the plugs I would check the fuel pressure.
I decided to half ass it a little. I went out and first looked at the wires..... they looked new. Then I looked at the one of the front plugs and it looked new. I then (using a hand mirror) I pulled one of the plug wires on one of the front plugs and visually inspected the visible part of the plug and it looked like the front ones (new looking). I think one of the previous owners changed them all out not too long ago....at least they don't look 30 years old anyway
If the fuel pressure checks out the next thing I would look at is scanning the ECM before and during starting to see if any of the sensors are wacked out. Perhaps your coolant temp sensor or intake air temp sensor are giving you troubles.

Ok ...some new data. I drove the car a couple of afternoons ago.....again it started hard. This morning when I started it up to come to work (about 6am) it started easily. Sooo.....seems to be starting easily when they ambient air temp is cooler outside (It was probably in the mid 50s this morning, based on condensation on the car)....and it started hard when it was warmer out (like around 75-80 degrees). I am not sure what that actually tells me. I do have a new IAC sensor and CTS that I installed a few weeks back because of poor running conditions when cold (started ok but ran poorly until up to temp).
