Does it have good spark? The crankshaft position sensors are really common to go out on these, causing no spark.

Have someone check for spark at the sparkplug wire. Then if you have spark, get a can of starting fluid and spray a small amount into the air intake. If it tries to start, then the injectors are not being told to open.

You see pressure in the fuel rail does not mean the injectors are working. It just means the fuel is available for the injectors. And having fuel pressure means the fuel pump is working.

You should get a Code for a throttle position sensor as one thing that can keep the engine from starting. The firing commands and fuel injection commands get info from the magnetic pickups on the crankshaft sensor and on some models camshaft pickups. These report to the PCM or powertrain control module.

The self-diagnostic feature should generate a problem Code for anything missing in action. You may want to check the PCM or ECM relays in the powerbox. Autozone will provide wiring diagrams free when you register your car and scroll down to the pages' Help section.

Please rate my info.Try the starting fluid.

My 01 jeep 4.7 wont start died at stop ligh,t fuel pump starts when i turn key i smell fuel turns over fast but start, wont even try

If you are smelling fuel, there may be a good posiblility of a fuel leak. This must be checked first for safety of you and your car. The fuel system runs by a high pressure fuel pump. If there is a fuel leak and the pressure is not building in the system, the engine will not start.

Car just turns over wont start

When you turn on the key, the fuel pump runs for one second to bring the pressure in the fuel rail up to spec. If it does not do this, the car won't start. Have the fuel rail pressure tested. It should be between 35 and 40 PSI. Suspect the fuel pump relay. There could also be ignition problems, but make sure this pressure is ok first.

Wont start

I'm assuming the engine is cranking over while turning the key and wont start. from this assumsion it possible the cam sensor on the timing chain is broken. or no fuel pressure. to test for fuel pressure, turn the igntion key on, locate the fuel line & port on the fuel line, remove the cap & depress the small screader valve by using a small pocket screwdriver, fuel should shoot out with a lot of pressure. no fuel shooting out most likey the fuel pump is bad. if this has good pressure the cam sensor is most likey the cause. to replace the sensor, you need to replace the timing chain.

CAR WONT START

If the car fired after pouring gas into the engine, then you should check your fuel pump, listen when you turn on the key, if you hear the fuel pump start and stop, then check your fuel pressure, all fuel injected vehicles have fuel pressure regulators, if your fuel pump isnt pushing enough pressure to the regulator the car will not start, and if it does start it wont operate properly, and may even leave you stranded.. If your fuel pressure is low, check the fuel filter, dirty filters restrict pressure, and are ALOT cheeper to replace than a fuel pump!

what is the fuel pressure reading, bet it's zero. replace the fuel pump and the fuel filter. when fuel gets old it gums up the pump and it won't spin and produce pressure, very common complaint on stored cars, i.e. no fuel pressure.

When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.
