Compression, the rings sealing properly? get a compression tester and follow the instructions.
use a compression tester.
A box compression tester is a machine that measures the size and quality of boxes. It uses a variety of techniques to test the strength, durability, and compression of boxes. The box compression tester can also be used to test the strength and compression of packaging materials. Most manufacturers use this type of machine to test the quality of the boxes they use to ship their products.
The most common use for a compression tester would be to check the compression in the cylinder of an engine. It will tell you whether there is a problem with your rings, blown head gasket, or perhaps a cracked cylinder head. Older compression testers use a diaphragm or spring for resistance to measure the pressure, but there may be newer ones that are constructed differently.
You need to start with the three basics fuel spark compression if you have all three it will run in the case of spark it could show spark when ur testing it but under cylinder compression it could be weak fuel is easy take carbs off spray fuel in intakes and crank if carb or fuel is an issue then it will start compression is easily checked take plugs out and crank with hand close to plug hole if air pushes past u have some sort of compression the best way is to use a compression tester or cylinder leak down Gage to pinpoint the loss of comression
plugs, wires, cap, rotor botton, air filter, PVC vavle, fuel filter, now tools you may need. rachett, plug socket, screwdriver, timing light, fuel line tool, and if you do it the way i do you will also need a compression tester, fuel pressure tester, and code scanner
verify that you have spark and fuel connect a spark tester to the spark plug boot on the bad cylinder crank the car and see if there is a spark connect a fuel pressure gauge at the fuel filter service port the top bolt on the banjo bolt connecting to the fuel rail and injector pulse tester to the injector on the bad cylinder MAKE SURE YOU RELIEVE FUEL PRESSURE FIRST BY REMOVING THE FUEL CAP next after everything is connected put the cap back on crank the engine for a few seconds to build pressure activate the injector pulse tester and watch your fuel pressure if it drops you have fuel before you disconnect everything once again relieve the fuel pressure if all that is ok do a compression check disable the fuel pump by disconnecting the electrical connection @ the fuel pump under the rear seat remove the spark plug and connect a compression gauge crank the engine for about 7 seconds and see what your compression is put a little bit of atf into the cylinder and reconnect the compression gauge and crank again for about 7 seconds if your compression went up quiet a bit your piston rings are bad if your compression did'nt really change then it's your valve's try doing a valve adjustment
It could be a number of things. The first things you ask yourself with a poorly running engine are, is it getting air, is it getting fuel and is it getting spark? From there(if it has all of those things) is to check for compression and check for vacuum leaks. This can be done with a compression tester and a smoke tester. From there, if it is still running poorly and has good compression, no leaks, its getting air/fuel/spark you should look into whether or not the ECU is still good. Hope this helps, good luck.Chris Young--Americanmuscle.com Customer Service Representative.
thats a little on the worn engine side of compression,but that in itself would not keep it from starting....most likely a fuel or spark problem. you can check fuel pressure with a screw in guage from autozone,and check spark with an inline spark tester from autozone.
Box compression tester in Gujarat uses as a tool to check an engine's compression. It enables the user to gauge the engine's pressure output to make sure it is operating effectively. Compression testers are necessary for both detecting engine issues and optimizing engine configuration.
The compression tester has a plug that goes in the spark plug hole and reads the compression within the cylinder. Remove the sparkplugs. (Mark the plug wires with masking tape so you can put them back where they belong) Insert the compression tester and have someone activate the starter and roll the engine over a few times.
