There are number of reasons which can lead to no start of the car but if the starter is spinning and the sparks are flying, this can be caused by some problem of your fuel system. If you have a fuel injected vehicle, it has number of subsystems and any one of them could be the culprit. Here are few diagnostic tips from fuel filter manufacturer experts of Paracha Auto Parts Co. to narrow down the main sub system behind this problem.

Electrical Connections

Fuel injection system has plenty of electrical connections. On top of every fuel injector there is an electrical connector. There are also number of connections on the air side of the intake and on the cylinder heads. You need to check every electrical connection you can find in the fuel injection system to make sure it’s tight.

Fuel Pump and Relay

You have to do a fuel system pressure test for checking your fuel system. But as most of the drivers don’t have the required equipment for performing this test, first you have to check the electrical connections. Use a circuit tester for testing the positive side of the fuel pump. If there is current, move to the next step. If not, check the fuse but if it’s fine then the main problem is your pump relay.

Fuel Filter

If your fuel pump and relay is working fine but fuel is still not reaching the engine, your fuel filter could be clogged. As a thumb rule you should change your fuel filter every 12,000 miles or as suggested by most of the fuel filter manufacturers.

These car parts can be checked by yourself at your own garage and with easily available automotive tools. But some parts of your fuel injection system need electronic diagnosis. For this you need to take your car to a professional mechanic.
