You could also buy a new strainer at most auto part stores and replace it if your budget is tight. This problem is present mainly with fuel pumps that are combined with the fuel gauge sender. Bad sensors can often lead to misdiagnosis of faulty GDI pump when it’s really a faulty sensor problem. The spray tip (where the fuel leaves the injector and enters the combustion chamber) is particularly prone to “backing up,” so to speak.If your engine has ever sputtered or hesitated during acceleration, a clogged fuel spray tip might be the glitch. A faulty fuel pump can cause a variety of different fault symptoms and can sometimes be a little tricky to inspect and diagnose correctly.eval(ez_write_tag([[580,400],'themechanicdoctor_com-medrectangle-3','ezslot_2',122,'0','0'])); To help you with that, this article will explain how most common automotive fuel pumps work, highlight some of the different pump types, as well as to pinpoint some of the most common problems and how to fix them. The car only been driven has 85,000 miles and in my opinion a fuel pump problem is premature and unsafe. A valve within the fuel pump may not be opening, causing more fuel than necessary to pour into the engine system. Once it’s started, I wouldn’t stop the engine until the car is parked somewhere you can work and fix that out though! If the engine is not receiving enough fuel, it will try to work harder. V23084-c2001-a303, -403 , the coil of the fuel pump relay not activate, so the pump not receive the 12 V, this coil must have a resistance of 260 Ohms and I have a measure above 1900 Ohms. Overheating will reduce the lubricant property of engine oil and will cause a metal to metal contact. As opposed to an electric fuel pump, which is running inside a fuel tank with almost no lubricant at all, the GDI pump is lubricated by the engine oil. If a car is moving at an accelerated speed, perhaps above 50 miles an hour, and the vehicle starts jerking and then resumes regular performance, it might not be a bad spark plug. Sputtering Under Acceleration But, especially for a fuel pump, I suggest you switch step 2 and 3. If not, the fuel pump may well be seized. The fuel pump is typically located right below the rear seat. When the fuel pump is heated frequently within a few moments of turning the vehicle on, such as is common in stop-and-go driving patterns, the fuel pump may overheat and cause the engine to overhead too.

Check your ECM fuse. A rising temperature paired with stalling often indicates a problem with the fuel pump motor. When the fuel pump relay fails and your car still starts (it may not), you will probably have issues with poor acceleration, stalling, or stuttering. Bare wires could spark and ignite fuel vapors. Anyway, you won’t see those pretty often unless you work on old muscle cars or marine engines. Tryed spraying fuel into the intake and the car will run for a … Testing your Corsa’s fuel pressure on each side of the pump would be the best way to diagnose this problem. This and other issues can cause the owner a great deal of stress and expense. There no easy way to really identify a mechanical problem, other than checking the fuel pressure with a fuel pressure gauge. Over time, residue can build up in the fuel system, and enough gunk, grime and grease can clog up the entire fuel injector pump. It’s not a common problem but, sometimes, the fuel pump could start to make a loud whining noise.
