Removing a couple of screws from the cover and pulling the cover back should allow you to see the belt. The belt is usually enclosed inside a plastic cover on the end of the engine. Next, check the timing belt if the engine has an overhead camshaft and rubber timing belt. No spark would indicate an ignition problem such as a bad crankshaft position sensor, ignition module or ignition coil. If the ignition system is working properly, you should see a series of sparks while cranking the engine. Then place the coil and plug so the plug is touching metal on the engine. If an engine has a coil-on-plug ignition system, and it is possible to remove one of the coils, do so and place a spark plug in the end of the coil. The tester must be grounded to the engine block for a good electrical connection.ĬAUTION: Do not touch any of the spark plug wires while the engine is being cranked or you may get a bad shock! This can be done by connecting a spark plug tester to a plug wire while the engine is cranking. Engine Cranks But Will Not StartĪ dead fuel pump can prevent an engine from starting, but so can a problem with the ignition system or the engine itself (such as a broken timing belt). A pump that can deliver adequate pressure but not enough volume may allow the engine to start and idle normally, but it will starve the engine for fuel and cause a loss of power when the engine is under load, accelerating hard or cruising at highway speeds. Low pressure will cause starting and driveability problems.
No fuel pressure will prevent the engine from starting, or will cause the engine to quit running if the fuel pump fails while driving.įuel injected engines are very sensitive to fuel pressure as well as fuel volume. Low fuel pressure can cause hard starting, a rough idle, misfiring, hesitation and stalling. If the fuel pump is not delivering adequate fuel pressure and volume to the engine, the engine may not start or run properly.
