My aim is to give you the best service possible and to help you. If you have any questions or concerns, please don’t hesitate to let me know. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible.
So when you turn the key to start it, does the engine rotate? If it does, do you have spark and fuel pressure? Fill me in with as much detail as you can about the starting trouble.

spark..just no startNo son isn't home he has been the one working on itWe have new battery,new fule pump,new plugs...he looked at relays..he said they were fine...my son doing the workIf it sits for 1 hour or more it will start right up..other times..no ..but mostly yes

Thank you Roxanne. So it cranks over it doesn't start? Can you check for codes in the computer? Have you checked the fuses?

Yes thank you. If there is no spark while cranking and all of the fuses are good this could indicate either a faulty camshaft position sensor or crankshaft position sensor. In addition the timing chain could have broke or jump Time which confuses the computer which can cause no spark condition. Your best bet would be to start by checking or replacing the sensors, checking engine compression and then checking for any codes in the computer with a compatible scan tool

OK thank you. If the engine has spark check to see if it runs and starting fluid. If it does this would indicate if your delivery problem. Possibly a faulty fuel pump or an issue with the fuel pump circuit. If it has spark it doesn't run on starting fluid then again you're gonna wanna check engine compression and check the base engine timing

It won't start up again tell it sits for a bit like an hour or more

Got it. At that point you need to check for spark and fuel if it's cranking and not starting

And when it doesn't start it cranks over but doesn't start correct?

Ok got it. You are going to want to start by checking all fuses and check for codes in the computer using a compatible scan tool [like this one](https://www.amazon.com/Autel-AutoLink-AL319-Scanner-Automotive/dp/B007XE8C74/ref=sr_1_7?dchild=1&keywords=obd2+scanner&qid=1589589090&sr=8-7). If there are codes in the computer, you can reply back to me on this page with the code number or numbers and I can help you pinpoint the root cause. If all fuses are good but there are no codes in the computer, we will have to pinpoint what the engine is missing when this no start condition occurs…
Spark
Fuel
Compression
First is the fuel system. There are two way of checking the fuel system. First, there is the fuel pressure up to the fuel rail. Normally this is checked using a fuel pressure gauge. You simply hook it up to the fuel rail, turn the key on or crank it over and take a reading. Most older vehicles have a fuel pressure test port. This means you can simply screw the fuel pressure gauge onto the fuel rail with ease to check fuel pressure. If not, you can tap the fuel pressure line going to the throttle body or fuel rail (depending on your system) and take a reading that way. The newer vehicles use a fuel rail pressure sensor. It will take a pressure reading off of the fuel rail and turn it into a digital signal that the computer will see and understand. You can see this under live data in the ECM or PCM using a compatible scan tool under “live data”.
The second part of the fuel system would be the injector pulse. This is the signal from the computer to the injectors to tell them when to open up to allow fuel into the engine. Normally this is tested using a tool called a noid light. You simply plug the noid light into the injector connector after disconnecting the injector connector from the [fuel injector](/topics-fuel-injector-dodge/) and watch it while an assistant cranks it over. It should blink if it has power and a ground signal trigger from the computer. This is a good signal. Both parts of the fuel system are very important and must be present for the car to start.
Next would be the ignition system. On a standard ignition system, the secondary ignition components should be able to deliver strong bright blue spark that can jump at least a half inch of a gap while cranking the engine over. You can check this on more than one cylinder to be sure the ignition system is working normally like it should. Depending on your set up, you could have ignition wires that send the ignition to each cylinder or you could have coil over plug (which is very common). Either way, simply access the wire or coil and insert a spark tester or screw driver in place and ground the other end. Watch for night blue spark while an assistant is cranking the engine over. There is also the primary ignition system too. This is the engine speed sensor or sensors (cam or crank sensor). Some vehicles use just the crank sensor and others use both the cam and the crank sensor to produce spark. On some more complex vehicles and engines, there might be 2 or more camshaft position sensors that can affect spark. Both the primary and secondary ignition system can fail (and even intermittently) causing a no spark condition. If there is no spark while cranking, be sure to check for power to the [ignition coil](/topics-ignition-coil-dodge/) or coils with the key on and while cranking the engine over. Yes this could be a blown fuse or relay causing a no spark condition. Some vehicles or ignition systems use an ignition module as well as the coil or coils, and others are triggered directly from the engine computer but will still need a separate power source for the ignition coil(s) to work.
As far as compression goes, low or no compression could be caused by base engine mechanical issues such as a broken camshaft or timing chain (although this usually is not intermittant). You can check engine compression, remove the front timing cover and take a look at the timing marks or possibly pull the valve cover to see if there is any visual damage that you can see. Checking compression requires a compression gauge. Simply screw the tester into the spark plug hole after removing the spark plug and crank it over to take a reading. While the compression specifications vary a bit depending on the engine, basically you want to ensure compression is relatively the same in all of the cylinders.
All three of these are tested when the engine is being cranked over. A compression tester, spark tester, fuel pressure gauge and noid light are all accessible at your local auto store or online. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.
You could also see if it runs on starting fluid once you know the engine has spark. If it does, then you know you have spark and compression and you simply have a fuel delivery problem.
Here is a video explaining how to check for spark and fuel on a car that cranks but does not start.
