You need 3 thing to get an engine to start. Fuel, air and spark. remove any one and you get a No Start.
No start even with starter fluid suggests there is no spark to ignite the fluid. Try going back to basics. Check the silly, obvious stuff first. Yes, I've been caught out by these,
Is the battery fully charged? is the air filter clean? Is there fuel in the tank? Have you checked for spark at the actual spark plugs?
When you crank the engine what exactly does it do? This will give clues as to the cause. If it just turns as it cranks suggests no spark, Trying to start but not running suggests fuel supply.
- Check you have spark all the way from the spark plug to the coil pack and power to the coil pack itself.
- Is there fuel getting to the cylinders?
- Is the air intake system clear and not blocked.
Check for spark.. pull one spark plug out set it on bare metal(away from cyl hole fuel could light from spark) turn vehicle over and look for spark should be a nice lightning bolt looking spark... blue spark is weak spark.. and see if it's getting spark...,, if not,,."try new plugs.,wires,distributor cap&rotor " also first.spray a little starting fluid down the injection system turn it over and see if it fires.if it does then it's a fuel issue prob not electrical... try that.hope it helps
You need 3 basic things to make an engine run. 1 Compression, 2 Fuel, 3 Spark. So start buy checking for spark, remove a spark plug and plug it back into the wire. Now touch the threads of the spark plug to metal ( a good ground on the engine) and then turn the engine over (try to start it) and see if you have spark? No spark find the problem. If you have spark now see if you have fuel getting to the engine. You can try pouring a little fuel into the carb or throttle body and then see if the engine will fire or try to run. If it tries to run or fires you have a fuel problem. You need to find out why it is not getting fuel. Spark or fuel, 90% of the time are the main causes when an engine will not run. I hope this gets you started. Rod
Spark or fuel. Start with spark. There are inexpensive little test lights that will let you know if you're getting spark. If you have spark, start looking for a problem in your fuel system. Do you hear the pump kick on when you turn on the key before you start cranking? Is its air choked off? In line fuel filter that could be clogged? Fuel pressure? Injectors firing? Start with the easy stuff and rule out possibilities one-by-one until you find what's keeping the engine from getting spark, air, or gas.
If no fuel is getting to the plugs the inyection system is not working. Check for spark in one spark plug. If you don't have spark that is the reason why the injection is not working. When there is no spark, the ECM or injection computer won't work because it needs a signal from the coil, as s proof of spark..
If you have spark, and the timing is good, you are either not getting enough fuel or there is not enough compression. If you checked the spark from the spark plug wires and got a spark, try changing the spark plugs. The spark from the plugs may be too weak to ignite the fuel.
Have you changed your fuel filter? This is a very common cause of a no start condition. Have your fuel pressure tested to ensure you are getting the correct amount of fuel. Also, you could try replacing your Fuel Pressure Regulator.
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.

If the engine

The engine needs adequate fuel pressure, a properly timed spark and
normal compression to start.
