Sounds like the fuel pump, clogged fuel filter, or a stuck needle and seat in the carburator.

ISO definitive eng compartment pic/diag/schematic of fuel line & line-pressure valve/access, bleed disconnects + alt intake spots 4 starting fluid, beyond air filter intake.

to remove contaminated fuel , pull a fuel line of the fuel manifold and run the pump for a few seconds
not firing is sensor , immobilizer , ignition module problem but you stat that it fires on starter fluid so that cannot be right
starter fluid is a d good way of damaging the engine
a better way is to find and fix the fault
now to try and sort out what you are saying
it is cranking so the starter is good
it tries to run on starter fluid so there is spark to the plugs
it will not run and that indicates a lack of fuel to the injectors
a lack of fuel indicates
1--- a bad fuel pump
2--a vacuum in ht e fuel system from the tank not venting properly(EVAP system)
3--- fuel pressure regulator not working and providing pressure to the injectors
4--- bad injectors --- need cleaning
dump the starter fluid , buy a workshop manual and fix the problem properly

My '96 Chevy Lumina starts runs fine but when I shut it off and try to re-start it won't start. I wait for a couple of hours and then it will start. I've replaced the cam and crank shaft position sensors....

Ignition control modish. Or. Fuel pump. Get s fan of starter fluid. When it won't start first no more than one single second of starter fluid in the air intake. Do not press tbe accelerator as you crank it.
If it fires up. It's your fuel pump.
If it doesn't it will probably be your ignition control module.
I'd put my money on the fuel pump. Do the starting fluid test to know for sure.
GM fuel pumps of that era lasted about 140,000 miles. Most others last about 200,000.
It's going up be your girl pump. But do the test. First. .

Were to start troubleshooting on a 2001 Mercedes Benz ML 430 cranks but will not start

First try to squirt some starter fluid in air intake, then try and start , if fires and runs for a split second then dies, most likely possible fuel pump bad. Thanks mike. Please let me know on results of starter fluid, then we go from there.

Firing order for 1966 ford mustang 200 cubic inch

The engine is a 200 CID straight six, the firing order is 153624...


Just pop the distributor cap and have someone crank the engine while you watch the rotor.

How I can determine which hole in the distributor is assigned to the #1 plug wire.
Pull the number one plug. Turn the engine over slowly (with a wrench) while holding your finger over the plug hole. When the air builds (a lot of) pressure you are coming up to the number one spot on the distributor. (the rotor will point to the location of the #1 hole in the distributor.)

Quick methods to disable the engine I have seen people do on the classics:
Close the points by loosening the set screw
Pull the rotor cap
Connect a wire from the coil to ground. (effectively closes the points. Can damage the coil if key is left on.)
Pull the main ignition wire
And there are some tricks at the starter solonoid involving the ballast resistor bypass that is used to provide a hotter spark while cranking. (Two little wires at the starter solonoid - one is crank the other is the ballast bypass.)

Might give those a look-see. Best of luck (rememeber rated this help).

Won't start after storage

How long did you store it? Gas goes bad in as little as 5-6 months, if it fires with starting fluid then you need to drain the tank and fill with fresh fuel.

Car was running, now quit and won't fire up now?

Take a spark tester and plug it into the wire and plug and see if you have spark. Now take a can of starter fluid and spray it into the air intake to see if it will start. If no spark, it is electical. If it starts with starter fluid, no fuel, If it has spark, but won't start with the starter fluid, good chance timing chain, or sensor is bad. That old if the timing chain has never been changed...good place to look after the other tests pass.

Truck wont start. battery test good.truck cranks over,but drags down after a couple of tries,has new starter and spark plugs, truck has good fire from coil but weak fire to the plugs could it be a moduale...

drags down and then clicks? then is a dirty batterie post if that is not it, then there is a fuel problem to check, starting fluid spray through the intake air, make sure not to spray directly onto the map sensor.

1966 ford f100 will not start repalced points plugs wires coil voltage regulatornot getting any fire

Have you checked the starter solenoid? Replace this and see if you're getting fire then. They are usually suspect and the first link in the chain between your battery and the distributor.
