Clogged fuel injectors would be the most likely issue if it sat a long time, but it could be many things. Pull the plugs to make sure they're not fouled up, then crank it to verify it's getting spark. If they check ok try a squirt of starting fluid to see if it'll fire up. If it does run, hit it with a dose of Techron fuel additive to help clean up the injectors. I usually go at least double the recommended strength for dirty injectors and you can go higher without damage.

    Thanks Donzi. Will check the plugs and then the injector. With the fresh gas I will ad the fuel additive to see what happens.

    So I concluded it was the fuel injectors that were clogged and pour a 1/2 bottle of SeaFoam solution in the tank. Let it sit for a day and it started. Thanks for all your inputs! Appreciated."

Hi Chris, great answer from Donzi, definitely a first look. If that doesn't produce desired results check speedo for a blown CPS. Good luck.

Turns over wont start

You need to figure out what you do not have that an engine needs to run. What is the fuel pressure at the fuel rail? Do you have spark when cranking the engine? Are the fuel injectors operating? Do you have ample compression? When you figure out what you do not have, that will tell you what you need to fix.

87 olds cutlass ciera 2.5 4 cylinder cranks no start the fuel injector not spraying but if I put gas in carb it starts but then dies anyone know whats wrong

I'd have to use a gage and check proper fuel pressure. Also, I'd have to check fuel injector pulse. The fuel injector needs voltage and ground.
If the computer doesn't see rpm signal, it won't ground the fuel injector. Sometimes the ignition module is at fault? There could be other issues? I hate to see you replace anything w/o testing.

2000 ford 4.0 explorer cranks but fails to start. It acts like it starts after sitting all night but then only cranks, what is wrong?

Check for spark to the sparkplug. Try a shot of starting fluid as having gas pumping and having the fuel injectors opening are 2 different things. If you have spark, then the fuel injectors may not be working. Quick diagnosis is to use starting fluid and see if engine tries to run. This indicates problem is not lack of spark but lack of fuel getting into cylinders.

Car won' start, battery is ok, antifreeze is low but not out could this be the problem?

No. it wouldn't keep it from starting. If the engine cranks but won't start, probably gas or spark (ignition) related. Do you hear the fuel pump in the tank turn on for a couple of seconds, when turning key to on, not start? If you cannot hear the pump, better check if you are getting gas up to the engine. Maybe the fuel pump quit, or the pump circuit needs looked at. The pump should briefly turn on with key on to pressurize the fuel system-the fuel line and the fuel rail where the injectors are. Then the pump will turn off, and only come back on again when the engine is cranking, and stay on when running.
Correct fuel pressure is important for easy starting, and good engine performance. Have the fuel pressure checked against the specification for your vehicle. If fuel pressure is good, check the ignition system-check for spark.

2002 Ford Explorer ran out of gas put gas in and won't restart. replaced fuel pump and fuel filter still won't start. Cranks but won't start

Most Fords have a fuel reset button. When you ran out of gas you tripped the circuit. Most of the time the button will be on the passenger side by the kick panel. The exact location should be in your owners manual or your local library or auto parts store will have a copy of one for your specific vehicle.

I was driving and the car cut off. It won't start but it cranks and won't turn over.It is a 1995 Olds Cutlass Ciera SL, 6 Cylinder.

your terminology is wrong.if it cranks its turning over what you mean is it won`t start(fire up) as you said at the beginning.anyways it sounds like you could have a fuel pump problem that stop working.this happens should check for spark at the plugs to make sure its not an ignition problem.did you notice a check engine light on when it was running.if so there will be a code in the ecm and may be the cause of your problem.
