Re: car will not start but will run on ether?
Does it have spark now sense you chg. that? if you do, it could be fuel problem. was there any other codes other than that one? maybe crank sensor, cam sensor. if you got spark at plugs, its got to be fuel problem.

You should take it to a ASE certified repair shop that has the diagnostic equipment to check it out , an I don't mean a code reader . I mean a factory scan tool that can look at engine sensor data PID'S ! It Just stopped running ? Will it start right up again or is it dead . Check for spark , that means pulling the Ignition Coil Housing an using special tool
J 36012-A , there just plug wires . Install a J 26792 Spark Tester on #1 spark plug jumper wire. Connect the #4 jumper wire to a good ground. Connect the other jumper wires from the 2-3 ignition coil to the respective cylinders,Connect the J 43298 Igniton Module Tester to the ICM.
Do a fuel pressure test ! With the Factory scan tool check the idle air control valve counts , an see if it can be controlled . 220 K miles , ever have timing chain replaced ?
It would be normal for the check engine light as well as the other warning lights to come on if the engine stopped running. You could scan the computer for trouble codes if you have access to a scanner or code reader. You would need to find out if you have spark to the plugs and fuel pressure to start the testing procedures.
You'll have to figure out if it is a fuel or ignition problem. When it quits running, quickly check for spark at the plugs and fuel pressure. Is the check engine light on ? Have you checked for trouble codes ? It could be a relay, the ignition module, coil, fuel pump, or a list of other things. Generally, a problem that occurs hot then goes away cool is an electrical part that is failing.
A lot of solutions for this. It could be fuel pump, timing, crankshaft sensor,. Question? Was the check engine light on before it quit on you? Hmmmm. If so we need to scan the codes to find out whats wrong. If not we need to find out if the problem is fuel related or electrical. How many miles on the vehicle? Good luck!!!!
For an engine to run, you need three things to happen inside the
engine, compression, fuel and ignition, without any one of these
components the engine will not run.
Compression - Engine
compression caused by crankshaft rotation and pistons moving up and
down inside the engine block. If the timing belt or timing chain fails
it will cause the camshaft to become out of correlation with the
crankshaft or allow the camshaft to stop rotating. Either of these
conditions will cause the engine to lose compression and sometimes
cause internal engine damage.
Fuel Delivery System
- The fuel system includes: fuel pump, fuel injectors, pressure
regulator, fuel filter and pressure lines. This system is used to
supply fuel under pressure to the fuel injection system, the lack of
fuel pressure or volume will cause the fuel delivery system to fail and
the engine to stall or not start.
Ignition Spark Delivery System -
The ignition system components include: spark plugs, spark plug wires,
distributor (if applicable), crankshaft angle sensor, camshaft angle
sensor, ignition coil, ignition module, knock sensor and ECM (engine
control module). The engine relies on the ignition spark to be
delivered to the combustion camber at the correct time. If the ignition
spark stops or is delivered at the wrong time the engine will not run
or run poorly.
If Your Engine Cranks but Does Not Start Follow this Troubleshooting Guide Most vehicles operate by the same principle; basic troubleshooting procedures apply to most cars.
Anytime you have a problem with electronically controlled components
such as an engine, transmission, ABS brake, or SRS (supplemental
restraint system, Air Bag)
inspect all fuses using a test light and check the under hood power
distribution center and under dash fuse panels. If all fuses test ok
continue to the next step.
Step 2: To
check for problems with electronically controlled components such as
an engine, transmission, ABS brake, or SRS (supplemental restraint
system, Air Bag)
and the fuses test ok a trouble code scan is needed to identify any
system trouble. Use a simple scanner tool to retrieve trouble codes and
see if they relate to the specific problem, like a crank angle sensor
failure code. If the trouble code present does not pertain to the
immediate problem like an EVAP code ignore it until a later time, after
the car is running. The reason we repair non-related codes after the
engine is running is because sometime false codes can be triggered by
the engine not running. Once the engine is running again the code
present might cycle and turn itself off. You might say "if the engine
doesn't run shouldn't it have a trouble code?" Sometimes conditions
occur that will not be detected by the computer, example: if the fuel
pump fails the computer cannot detect the failure, so the engine doesn't
start and the computer thinks everything is ok with no codes. If no
trouble codes are present proceed to the next step.
Step 3: The
spark plugs in your engine are used to ignite the compressed fuel air
mixture. If the condition of the spark plugs are fouled by excessive
fuel or carbon the engine will not start, backfire or run rough. Remove
all spark plugs to inspect their condition. Please use this spark plug
condition reference guide to see how the spark plugs are operating.
There are two areas to check for this problem. The fuel and the spark. There is a Timer for your Glowplugs and you should hear clicking and notice the lights dimming in Synch with the clicking. This should work with your "Start" lamp in the dash.
Test one or two Glowplug wires with a Testlight and see what kind of Spark you have. If the spark is present you need to pull about half of your Glowplugs, if not all, and Test them with Battery voltage. They should be uniform in glowing and be careful not to melt them. Any Glowplug that remains cold or sluggish should be replaced. If no Spark, then check the Timer or replace it. Some models may have a Relay, check with Autozone or Oreillys or similar for parts listing.
The Glowplugs start a cold engine. In a warm engine, the Timer will not engage at a certain temperature. Engine compression will ignite the Ether if the Glowplugs do not work, but compression will not ignite a cold diesel engine.
Fuel, if you have a bleeddown in the fuel system the pump may be weak or there is a hole in the line or bad "O" rings. The Ether simply gets the engine turning fast enough to siphon the fuel and draw it back to the pump. A shop can pressure check the fuel system for leaks or use a "smoker machine" for difficult to find leaks.
I hope this helps and you are happy with the info I provided.
Check the spark, remove the fuse to the fuel pump and remove one of the spark plugs. Connect the plug to its lead and position it well away from the engine against the truck frame (do not hold it) and turn the engine over, check the spark. If no spark it most probably a faulty coil. Check the impedance of the spark plug leads and replace any that are much higher than the rest.
My guess is that you have spark but no fuel, What?... OK this is what I think is wrong. Your pump is fine when at position 2 on the ignition switch however when you switch to position three to fire the engine the power to the fuel pump is momentarily disconnected. A leaking fuel pressure regulator or injector would drop the pressure in the fuel line and at the same time flood the engine making it impossible to start. Once you start the engine with ether the ignition is back to position 2 and the pump can make good any loss in pressure but because the intake mix is rich this will cause the engine to run rich too.
A good fuel system is capable of delivering 40 - 50PSI of fuel pressure and when switched off up to 90% of this pressure should be maintained for about 5 minutes, if it cannot check out the fuel pressure regulator and injectors. The fuel pipe should be capable of filling a pint pot in about 15 seconds, if it cannot check out the fuel filter is clogged.
Hope the above gives you some pointers
Make sure that all the wiring disturbed by the battery change was restored. Do you have the check engine light on? If so, rent a scanner and read out any code(s). Pursue the codes to repair(s). You can check the ignition by removing one spark plug wire, connect it to a spare plug and set the plug base on the engine. Have someone try the starter while you watch the plug--it should flash at regular intervals while the starter turns. If ok, let the car rest for a while, then have someone turn-on the key (don't try to start) while you listen at the fuel tank. You should hear the fuel pump run for a short time, then quit. That means the pump has built pressure and is awaiting start. If it continues to run, the pump may be toast and should be replaced. Change the fuel filter.
