'85 190E 2.3 will not start
 

Need Help Please! Car will not start either cold or warm. It will start if fuel is poured at intake and continues to run fine. This indicates that all electrical components are running good. Changed all the following components: new spark plugs and wires, caps, cold start valve, OVP, Klima relay, fuel pump, fuel filter, fuel regulator, coolant sensor, cold sensor, fuel distributor, fuel injectors, and idle valve. Do you think this is a pressure or a vacuum problem? but where? I really need your help. I already spent too much money on this car. Thanks!

That car requires at least 75psi of fuel pressure. Make sure that you have that pressure first.

Thanks Doc but where do I check the pressure and how does the pressure builds up? By the way, I also changed the fuel check valve.
