Question about Cars & Trucks
Turns over and over but no start
Sudden no starts are usually gas or ignition spark related. You could check for spark on a spark plug wire OR you could spray a shot of starting fluid into the air intake, and then try starting-if the engine fires up briefly, then you know it is a fuel problem-maybe the pump or the filter or an injector circuit problem. The fuel pump should turn on for a couple of seconds when turning the key to on, not start. This puts fuel pressure in the line and at the injectors. If you have gas up to the engine under pressure, the pump is working. You should still have the fuel pressure checked to make sure it is at the correct pressure for your vehicle-a worn tired pump may not be doing good enough.
If the starting fluid causes not a peep from the engine, check for spark. If no spark, the ignition system will need diagnosing. It could be a fuse or an ignition part failed-the coils, the ignition control module, the crank position sensor (for timing of the spark), the ecu, etc.
