SpotlessWales Posted May 5, 2015 Posted May 5, 2015 Hello,I am a new member and joined because i am hoping you can shed some light on some issues I am having with my relay. I am not sure if it is an electrical fault or a fuel fault but it is incredibly slow 90% of the time and the other 10% is like a new van, also I have to bump it most mornings because it just turns over and turns over but doesnt kick in. I had the plugs changed last time it happened and that helped for a few weeks, ive had it fully serviced to so unsure what i need to fix. Any advice would be very much appreciated Ant Quote
paul.h Posted May 5, 2015 Posted May 5, 2015 Welcome to the forum. Which engine does the van have and how many miles has it done ? A blocked fuel filter could affect the performance so if it has not been replaced recently is something to consider. Possible causes of poor starting could include:- If the fuel filter has been replaced recently and there is an air leak the fuel could be draining back and cause difficult starting.- If the engine temperature sensor is faulty it could be giving the wrong fuel/air ratio needed for starting.- If there is a fuel pump in the fuel tank and that is not working that may give difficult starting.- A worn engine could give low compression and poor starting.- Blocked air filter.- Engine not turning fast enough on the starter motor - battery voltage low/wiring fault/starter motor fault.- Incorrect engine timing (belt jumped).- EGR valve fault so not sealing - could also give smoke during running.
