I am having trouble trying to get my 86' Mercedes 190e to run. I have just replaced the cylinderhead myself. Everything went smoothly, I replaced the headgasket and numerous other gaskets that leaked on the whole engine. The car started right up when I timed it. We adjusted the fuel mixture to the right mixture, but then I pulled off a stupid mistake. I had a brain fat , and wanted to see if the spark plug distributor was tightened down, and by twisting it, I threw off the timing . For some reason, I could not get the proper timing right. I have adjusted the mixture as best I could, but finally could only get the car to run for 5+ seconds and then shut off. It's at a mechanic right now, and he hotwired the fuel pump relay somehow and the car was able to run again. I replaced the fuel pump relay, but for some reason, I'm back to square one again. The car only runs for 5+ seconds when started.

What could be the problem? I have made sure there was no leaks in the intake manifold, r&red everything on the top end as supposed to, and have a new fuel pump relay. The car runs when 2 pins where the fuel pump relay goes(runs rich though, do to my desperate attempts adjusting the fuel mixture, and timing to get it to run again), and currently has a spanking new fuel pump relay. Someone please help me !
