Hello,

Thanks for using FixYa.

Sounds like you have a crank positioning sensor issue... Have it checked, I bet that's the rat.

My car cranks but will not start RVR GDI mitsubishi


Check all fuses first, then with an assistant, check for spark with a spark tester. if there is spark at 2 plugs, check for fuel pressure at the fuel rail with a gauge. Engines need three things to run, fuel, spark, and compression. If there is spark and fuel, do a compression test, if the timing belt jumped/broke, you won't have any

2006 monte carlo engine cranks but will not start


If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check fuel proper fuel pressure. Check fuel injector pulse.

Check your security system.

Van cranks but will not start


Hi, if the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.

To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. IF it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine.

You can also remove the plastic cap and press the Schroeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine.
