Did you check for vacuum leaks at the intake? It might be choking on too much air. The intake manifold gasket could possibly have a large leak too. Good luck.

Why won't 96 grand am start ate being wrecked?


You will have to determine if the vehicle has spark as well as fuel pressure. Pull a plug wire off and ground it over the engine. Crank the engine and it should spark. If spark is ok, you will most likely have a fuel supply issue. You will need to hook a fuel pressure gauge to the fuel rail test port to determine if pressure is available. If no pressure suspect a fuel pump or power/ground supply issue to it

What's your question? Replaced timing belt on 2001 dodge stratus 2.4 liter and still wont start


Have you checked for spark on a plug wire with the engine cranking? If no spark, the problem is in the ignition system- the ignition coils, the ignition control module, the plug wires and plugs, the crankshaft position sensor, and the PCM-all are parts of the ignition system. Don't replace without testing- it will save you money.

Also check the fuel pressure at the engine, or at least verify the fuel pump is getting gas up to the engine. If you turn the key to on, not start, the fuel pump should turn on for 2 seconds to put pressure in the line and in the fuel rail where the fuel injectors are. Do you see a valve on the fuel rail, it may have a cap screwed on it. This is the test port to hook up a fuel pressure gauge and check fuel pressure. Autozone and others loan or rent fuel pressure gauges.

I've got a 2005 chrysler 300 and it won't start I have changed fuel pump, camshaft and the crankshaft sensor coils and spark plugs and i still wont start what could be causing it not to start?


Try to determine if it is fuel or ignition related.
Turn key to on, do you hear the fuel pump turn on for a couple of seconds? It should come on briefly to pressurize the lines and fuel rail on the engine. Do you have fuel at the engine under pressure? Easiest and preferred way is to check fuel pressure with a pressure gauge at the test port on the fuel rail. With key on, pressure on mpfi systems should be 40-50 psi.
If there is gas in the fuel rail, test ignition by checking for spark on the end of a plug wire, with the engine cranking over. If you have a blue snapping spark, then ignition is probably good-may want to check more than one plug wire. Hold the metal terminal end of plug wire 1/4 inch from a ground on the engine, the engine block or a bolt or metal bracket. Verify a blue snapping spark, repeatedly, as the engine cranks. An orange spark, intermittent spark, or no spark points to an ignition problem. One thing you haven't changed is the ignition control module. This module, when signaled by the pcm, is what cuts the primary current to the coils for spark to be generated.

If you have both gas and spark, check the fuel injector circuit. Post back if you need help with that. There should be an injector fuse that needs checked. Also a fuse for the fuel pump, if no pump action, besides the fuel pump relay.

Turns over but won't start. No symptoms leading up to break down.


I would start by checking for spark. Disconnect a spark plug wire from the spark plug. Put a screwdriver into the boot. and hold the shank of the screwdriver about 1/4" from a metal part of the engine. Have someone crank the engine and check for spark jumping from the screwdriver to the engine. Make sure you're holding onto the screwdiver handle. If there is spark I would next check for fuel. The best way is to put a fuel pressure gauge on the schrader valve on the fuel rail. In an emergemcy you can press the center of the schrader valve to see if there is fuel under pressure in the rail. Be extremely careful with this because you could end up with highly volitile fuel all over the top of the engine and possibly on you. The pressure gauge will also tell you if there is enough pressure to start the engine. The next step will depend on what you find with spark and fuel. It is possible to have both and still have a no start. A blocked exhaust system is one example.

Van cranks but will not start


Hi, if the engine cranks over normally when you attempt to start you car, but the engine does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION. The engine needs adequate fuel pressure, a properly timed spark and normal compression to start.

To find why the engine won't start, remove the air inlet tube from the throttle body, push the throttle open and spray a small amount of aerosol starting fluid into the engine. Crank the engine. IF it has spark and compression but NO FUEL, it will start and run a few seconds before dying. If it does NOT start, it probably has NO SPARK.

Another method to check for spark is to pull a spark plug wire off of a spark plug (if it has plug wires, coil-on-plug ignitions do not) and place the open end of the plug wire near a metal surface on the engine. Have a helper crank the engine while you watch for a spark. DO NOT hold the wire while doing this as it can shock you. If you see a spark, the problem is not spark, but most likely NO FUEL or NO COMPRESSION. If you do not see a spark, the problem is in the IGNITION CIRCUIT.

Proper fuel pressure is critical for fuel injected engines to start and run. You should hear the fuel pump inside the fuel tank buzz for a couple of seconds when the ignition is turned on (no buzz means the pump is not running and the engine is not getting fuel). You can smell the tailpipe for gasoline vapors after cranking the engine. If you smell gas, the problem is likely not fuel but NO SPARK. You can also remove the plastic cap and press the schraeder valve test fitting on the fuel rail to see if there is any fuel pressure to the engine (not a very accurate test because fuel pressure must be at a certain level for the engine to start, for that you need a gauge). Even so, no fuel at the fuel rail would tell you fuel is not getting to the engine.

My ram 1500 will turn over but not run


you need to determine if you have good spark at plugs while turning the engine over,if you do then you need to find out how much fuel pressure your pump is putting out,you can check this with a fuel pressure gauge and check it at the reed valve on the fuel rail,turn the key on and the pump will operate for five seconds look at your gauge you will need at least 55psi to fire the engine,if you don't you can try the fuel filter first.
