My car started fine mostly, but recently it got really cold. Like 12 degrees, and now it won't start. I checked the plugs for spark and it had plenty of spark. Fuel seems to be getting to the plugs as i've taken them out numberous times to clean them and put them back in and each time they had fuel on them. The timing belt seems to be in good shape. Now before the car would start and it would sometimes have a roughness to it for a split second then straighten up. Im beginning to lean towards the fuel filter? Also before when I would coast the car would jerk until it coasted down to about 40 mph, now im not sure if that goes hand in hand with my problem or not. When the car starts it runs fine except for the coasting, but now im just trying to get it to start. Perhaps fuel pressure regulator? Any help would be appreciated

Okay do below and get back with me asap with some testing results

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor camshaft and crankshaft sensors- Note: If it doesn't apply disregard it

It definitely has spark, that was definitely one of the first things I checked! I actually got the car to finally start, and it runs fine and starts good now, but everytime it's really cold weather like below freezing my car has this problem when trying to start, when it's warm out or even 30+ degrees it starts. It took me forever to start it this time, but it finalyl started. Perhaps my Engine Coolant Temp sensor is faulty?

Is there any certain way you would recommend checking them? I would need a volt meter to check the coolant temp. Sensor wouldn't I? The car will not start this morning. It just cranks and cranks. I got it started yesterday and it started everytime pretty easily until it cooled down.

Get a helper to crank the engine over and listen to the injectors if they clicking indicating its opening and closing.

Okay do you hear the fuel pump come on when you turn key On?

I got it started again! It seems to be an on going problem in cold weather though. The Injectors are clcikign. I even went as far as disconnecting the fuel filter and having my sister crank it and fuel came flying out, so I guess the fuel pump is working. I reassembled the fuel filter and the car fired up. The fuel filter didn't look clogged. So Im guessing the temp sensor is the problem?

The CTS is like the Carb choke it enriches the fuel for initial cold starts, also check the cold injector-Put some Heet on it
