My '89 300TE won't start. It ran great yesterday, no problems at all. The car needed a new thermostat, so I installed it this morning. So a few minutes later, after installing the thermostat, I went out to crank it up and drive it down the road....and it wouldn't start! I only let a small amount of coolant drip out while changing the thermostat.

It will crank over, it gets spark, and I can smell fuel. I checked the OVP, the fuel pump relay, and I unhooked the battery for about 10 minutes so maybe the car could reset itself. And still, the car won't start.

Could anyone help me with this? This is my main mode of transportation, so I really need to fix it asap.
Thanks in advance.
