SOURCE: 2001 expedition cranks but wont start

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.

1) 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.

2)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.

3)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..

SOURCE: no power to fuel pump car was running fine just

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

Car won't start 2003 Dodge Stratus sxt coupe cranks but won't start what could b the problem? I tried spraying starting fluid in the air system but it still won't start!

i would check and see if spark pluges are firing. you can take one out and plug into spark plug wire then let the bottom of the plug sit on engine and get someone to try to start while you look at the plug to see if there is any fire. if you have no fire or fuel it would be the crankshaft sencer. it could be the timing belt but the motor would sound different turning over then it used to.

If you spray starting fluid into the engine air intake does it fire up andie out? If so you have a fuel delivery problem, if no then you have engine mechanical issues or spark issues.

2000 Dodge neon starts and runs fine. But sometimes does want to start Engine cranks, but won't start

How many miles on the car? Have you checked the fuel pressure when it doesn't want to start? Do that first and then move on from there. To quickly test fuel pressure with no special equip get a can of starting fluid from the auto parts store, when it fails to start spray the fluid into the air intake of the engine well it is cranking, if it fires up then the fuel pump is likely not running on for some reason. This can be electrical in nature or just a failed electric fuel pump

if no crank sensor by timing cover, some vehicles are controlled at the distributor. the 95-96 have sensor by cover . before 1995 this its controlled by distributor. there is no "crank sensor" on that engine the pick-up coil inside the distributor acts as the crank reference for that engine. have a good day !! 4.3 vortex engine.

1997 ford expedition will not start turns over

Try spraying starting fluid into the intake of the air cleaner while someone else starts the car. Keep a continual spray going while the car is cranked. If the car starts more than likely the fuel pump went out.

Expedition won't start or even act like it wants to. Just cranks and cranks. I feel it might be fuel pump.

easy way to test for it being fuel.open air filter box spray alittle starter fluid.then try starting if it runs or fires over its fuel related.if not then its sensor or fuse related.hope that helps.make sure the fluid is ma safe.meaning mass airflow sensor safe.as some starter fluids will mess them up.

1998 expedition wont start

first of all its not good to spray starting fluid into the intake,its got a plastic "LOWER"intake and it can blow apart and **** too much air through it.Next reset the computer and it can be done by un-hooking the battery cable for a few minutes and if this works and runs for a while and does this again,then reset the computer again.If it does it again then maybe replace the computer..Then also check the fuel pump,it may sound like its working but it could have gotten hot and the plastic gear on the end may not be pushing fuel through when it runs for a while.
