Usually, sudden no starts are because either spark or gas has been lost. Spray some starting fluid into the throttle body intake, then try to start it. If it coughs and sputters and tries to run, then you know it was not getting gas. Check for fuel pressure, or check if the fuel pump is working.
If the starting fluid has no effect, the ignition system may be the problem. So check for spark. Buy a cheap spark tester and try it on a couple of spark plug wires. No spark when the engine is cranking over is definitely an ignition problem, possibly a bad ignition coil or bad ignition control module..
Start by checking all the fuses for fuel pumps, ignition, etc... CHECK ALL FUSES. Next you can check the spark by removing one spark plug and looking to see if there is any sign of gas/ wetness on it... Meaning if you're getting fuel or not to fire the engine. Reconnect the spark plug wire and set it on a metal surface, preferably the motor block or exhaust manifold. Have one person crank the motor over and the other person check to see if the spark plug is firing (sparking). Or to make QUICK diagnosis grab some "starting fluid" and spray into the intake for a second or two, then crank it over, if it sputters or starts then it's a fuel problem, if it does absolutely nothing then It's an ignition problem.
well first off you want to make sure your getting fuel and if you are getting fuel then check the pressure to make sure it is were it should be you can rent them from autozone for free it got a deposit but you get it back when you return it . if fuel is good check your spark pull out spark plug have someone try to start car look at the plug if you have bright blue spark in all your plugs spark is fine if orangeish color spark change ignition rotor and distibutor cap and wires you might as well do it all if spark and gas are both good
check crankshaft postion sensor as hard starts and on most cars if there bad they wont start also check camshaft position sensor they both tell your cars pc when to fire spark and to what cylinder to fire it to
You will not have a hot wire on the fuel injectors. The go for the injectors is a monentary high which means even when cranking over you will not see it with a multimeter. When cranking over after a bit you should smell gas if not you are probably not getting fuel. If you smell gas the you are probably not getting spark. This is most likely the senerio since you couldn't start it with starting fluid. By the way don't do that very often because it can damage your engine. There are several areas to look if you have no spark. The first is the distributor, the second is your coil and the last is your computer. Good luck. Please rate the helpfulness of my answer.
Yes...check the pump, filter and output. Also check the ballast resistor for the pump. Stop pouring fuel into the cylinder...instead, use carb cleaner and spray into throttle body (excess fuel in one cyl will contaminate your engine oil). If it runs normally after you get it started likely the pump is good (unless you have problems at high rpm's under power) Regulator is likely good as well...default is to more fuel not less.
To check fuel supply, spray carb cleaner into air inlet while cranking. If there is no fuel, engine will start for a second on what you sprayed. if nothing, likely either there is enough fuel and plugs are already wet, or there is another problem. (perhaps contaminated fuel?)
It cranks really good sputters a little and makes some loud pops but it will not turn over? FYI:Cranking and turning over are the same thing. When was the last time it ran. The gas could be bad. Did you get new plug wires as well. Try testing the distributor, remove a spark plug, plug it back into the wire, and touch the threads to ground and crank the engine. It should spark. Keep your fingers away, that's high voltage. Remove all spark plugs, spray some starting fluid in each cylinder, then crank the engine with the plugs out. This will clean any debris from the cylinders. Engines need backpressure to run properly, a major exhaust leak hence the popping, could cause it to not run. If you can get it started try to keep it going, full throttle, keep in the starting fluid, it could just need to get warm. I used to have one of them and they don't like it when they're cold.
