2.2l CRDi diesel 2012. It won't start. Sometimes it starts for about 4 or 5 seconds and dies. Low pressure fuel pump
is fine, no ECU codes
JA: Have you ever replaced the fuel pump, or is this the original?
Customer: Original. I tested by cranking and checking fuel flow. Also I bridged the fuel pump relay and the diesel is coming steady and strong
JA: What is the model of your '12 Hyundai?
Customer: 2012, 2.2l CRDi diesel. D4HB engine. I am in South africa
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Look, I maintained my BMW and Alfas for 42 years. Ner sent to garage but this car we bought for my daughter. Run for 15,000km without problems. I put an ELM327 in OBD2 connector and says no ECU codes. When I took off the fuel pump relay then it gave a primary circuit of fuel pump fault that was correct.
JA: Anything else you want the mechanic to know before I connect you?
Customer: also checked all the fuses.
