Re: car won't start...there's fuel all the way to the
You say there is fuel to the manifold but is it getting enough pressure, another thing is there injector pulse width you need a noid light, unplug the injector put on the noid light see if it blinks. not sure if that car has a immobilizer or not. The ingnition switch could be bad and not firing the injectors or there may not be enough fuel pressure.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Tip: The max point reward for answering a question is 15.
Fuel Pump - can you here the pump (usually under the right hand back seat) running with ignition on?
Fuel Delivery (injectors) - squirt some fuel (just a cap full) into the manifold.
Spark - pull a lead off a spark plug and use a spare spark plug resting on the exhaust manifold.
Crank sensor - Injectors won't inject fuel if the ECU thinks the engine isn't turning. Crank sensor is at the front right lower side and as it gets older, the wire gets brittle and breaks most of the time where it meets the hard end. The connector is under the throttle body and should read 500-600 ohms.
intake manifoold leak check all vacuum lines replace all vacuum lines if look cracked ,spark plugs could be fouled out by leaking fuel injectors, clean fuel injectors,replace fuel filter,replace air filter,replace spark plugs and wires,do tune up see if it helps if not.could have leaking intake manifold gasket or leaking egr valve,use engine vacuum gauge check engine vacuum for intake manifold gasket leaks.
Older Vehicle i am Not sure but if its carbureted then check ur floats. If its getting fuel to the Injectors/Carburetor then its electric! Check For Spark or Mani fold air Leak by spraying starting fluid on the manifold & Carb. if it kicks then u no the problem lies around there. if no luck then its either bad compression or Spark issue.. New Plugs ? Coils ? Check for spark if its getting Fuel.
If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.
Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.
The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.
GIVE IT A SHOT OF STARTING FLUID IN INTAKE IF IT RUNS FOR A MINUTE THE CONTROLER FOR INJECTIORS HAS PROBLEMS IF NOT CHECK FOR SPARK AT SPARK PLUGS THIS WILL TELL YOU REALLY WHAT SYSTEM YOUR HAVEING PROBLEMS WITH. USALLY IF THERES FUEL AT INJECTORS ITS A SPARK PROBLEM GOOD LUCK
I had a problem like this on a 1997 VW Jetta 2.0L. I suggest you obtain a multimeter, a gas pressure gauge, and a used injector from a junk yard. You need to find if the car has spark if it is getting gas and if the injector is firing. Plug a used spark plug into say # 4 spark plug wire and ground end against the manifold or other ground. Have someone crank the engine and see if there is spark. If there is spark then disconnect the electrical connector and plug in the used injector and hold in your hand. Have someone crank the engine and if it clicks as the engine revolves the injector is firing. Now if you have spark and an injector that clicks then put the pressure gauge in the upper line going to the injector manifold. Use a T so that the fuel can still flow into the manifold. If these three things check out. You need to also verify the engine is timed correctly and the timing belt did not slip a few teeth. I had a problem with my crankshaft sensor. I bought a new one and although I was getting about a .3 volt ac signal, I still had no spark at spark plugs. I wound up getting another new crankshaft sensor and read 3 volts ac from the new sensor. I then had good spark Hope this helps
If the above information is correct.
1. Good Compression
2. Good Spark & Proper timing
3. Good fuel Pressure, injector pulse , injector spray, & fuel quality( no t contiminated)
4. Proper & clear air intake into engine
Then the likely cause would be a restricted exhaust. disconnect the exhaust at the manifold, and retry starting engine. keep me posted, we will make her run!
