Car Forum / Mercedes-Benz Cars / November 2007190e 2.3 not getting fuel
Hello. Can someone please help? I parked the car 2 months ago after putting a lower control arm on it and was saving for tires, brakes and a front end alignment. I made an appointment at the tire and alignment shop to have the work done and the car would not start. It ran fine when I parked it. I can pour fuel in the carb and start it and it will run until it burns the fuel up. I am not getting power to the fuel pumps (there are 2 of them) i checked with a test light. If I need to check anything, please be sure to tell me where the gadgets are located. I am having a hard time finding the gadgets on this car. 1993 190e automatic trans. 114000K . Please help if you can. There's a fuel pump relay that powers the fuel pumps. That relay is probably the cause of the problem. You should know that these relays get tired and need to be replaced as they become intermittent after about 15 years use. As to where the relay is located, others here will have to tell you. You may be able to trick it into action by charging the battery to full charge and switching the ignition ON and OFF until you hear the fuel pumps run THEN crank the motor.

The 190 relais set is mounted in the fuse box on the left side of the motor compartment. The fule pump relais is the second largest nr 155 in http://www.detali.ru/cat/oem_mb2.asp?TP=1&F=201034&M=102%2E983&GA=722%2E410&GM=7 17%2E404&L=765%2E902&CT=F&cat=500&SID=54&SGR=045&SGN=03 SignatureRoland Franzius Attention!! The Fuel Pump Relay 8the one numbered 155 in the figure) in not in the fuse box, but in the opposite side of the motor compartment, behind the battery. There, you will find a plastic panel that separates the battery from the relay zone. Relays that lies here are the ASD Relay, the Fuel Pump and the Klima relay. All they receive some signal from some sensors from many parts of motor. You can verify if the problem is the fuel pump relay, attaching a led diode between the Pin 87 of the relay and the ground. You need to put a 820 ohm resistence among the catode and the ground. If the led turns off while the motor stops, 95% the problem depends from the relay. Think that the relay receive also a RPM signal that is divided between fuel pump Relay (TD pin), the ASD relay and the tachimeter. If this signal is abnormal the relay enter in 'protection mode' and the engine stops. Hope this can help Alessandro > -->> T.G.
