Install a new EGR and EGR pipe to the newer one on my 95 C280. Once completed, I notice the idle was not as usual. During the process of removing/installing the EGR pipe, I had to pull the injector rail and loosen the Intake Mani. When reinstalling the injector rail, I noticed that the seals looked dry but just put some oil on them. Drove the car for a week without improvements.

Thinking the seals was causing my unsteady idle, I ordered a set of upper and lower injector seals. Replaced all the injector seals, let the system prime and attempted to start the car. Car would not start! Got out and looked under the hood to find gas everywhere. The upper seal on Cyl 4 was spilling gas everywhere and all over the garage floor. Cleaned up everything and changed the seal with an extra one purchased.

Now, the car starts for 2 seconds and then stops. Will not start again for 3-5 mins, but only runs for 2 secs. Pulled and tested the spark plugs; they are dry and have spark. Tested at the fuel pressure relief valve and it squirted across the room. Got spark, got fuel, got air = No Start!! What should I try next??
