Check fuel system of vehicle

Image
  How to check 100% functioning of fuel system in Vehicle ( Vehicle not starting ) 1. First We have turn car key into before starting position (till lighting dashboard indication) and check that priming sound of fuel priming pump in or near to fuel tank. If fuel pump sound not coming check the fuel pump fuse and check voltage in fuel pump connect socket. 2. If sound ok further check fuel pressure (35-45 psi) by connection pressure gauge into fuel in line of main engine. If fuel pressure dropping it can be problem of fuel regulator, fuel injectors or fuel pump itself. If fuel pressure not there it can be problem of fuel pump, fuel filter or leakage of fuel in system. 3. If it's ok. Then you have to check fuel injectors for good injection to engine. You can check fuel injectors by using injectors test kit or simply you can change it by new one check the status. 4.

Vehicle cranking but slowly

Image
Car crank slowly. Here is the solution 1. First check batter indication in dashboard. Further check clock time and it isn't correct definitely your vehicle battery power disconnect or battery dead. 2. Check battery connection luges and terminals for any corrosion or tightness. If any corrosion there using baking soda and hot water can remove corrosion particles easily. If battery terminals damage or loss We have to change terminals. Further if you can by a multimeter can check voltage of battery (12.4 to 12.6 V is good) 3. Alternator not working or alternator belt damage can be cause to battery dead. By using jump start you can start engine and take vehicle to nearest battery charging station and check the battery. 4. Finally check starter for voltage drop. If it is change the starter. I think this will help you to figuring out problem to slow cranking of engine. If you have any suggestions or questions I'm very happy to take it and give you better solution.
