SOURCE: Car getting too much fuel at spark plugs

Hello Velma!

It sounds like ther might be an intermittent ignition (spark) problem... when the plugs don't fire, they will get wet with fuel...
So check all of the ignition components, make sure there are no loose connections to the coils are plug wires.

It is also possible that there might be a problem in the fuel injection, such as an injector stuck open and continuously feeding fuel to its cylinder (which would show as only ONE plug being wet), or possibly a bad fuel pressure regulator, letting fuel pressure in the injector rail go too high and causing an over-rich mixture and engine flooding (symptomatic of ALL plugs being wet).

Once the engine is "flooded" it is sometimes hard to "clear" the engine with modern injection systems, but try this: Hold the accelerator to steadily to the floor while cranking --- DO NOT PUMP THE PEDAL! --- This will allow the maximum amount of air to mix with the overage of fuel in the cylinders and help the engine to eliminate the excess without also adding too much back in...

If you still can't get it to fire off doing the above, then remove the fuel pump relay or fuse and repeat the above until the engine tries to run.... It will run briefly until it fuel starves and dies. Then replace whichever you removed and try starting again with fuel delivery back in service.

Velma, I would have answered this sooner, but I've been on a "road trip" and only recently got back home. If you still have problems, please post a comment describing as best you can the situation --- you have to be my eye, ears, nose, and hands in this long distance effort! Also let me know why the head gasket blew, if known... Racing or overheating? If this does help, please remember to rate my assistance --- your approval is my ONLY compensation for providing this help!

Did he physically check the timing? IE pulled the timing cover off? You need a good scan tool. See if it shows cam and crank sensors, and if they are in sync. If you are infact getting fuel and spark, it should run, but you are not getting one or the other.

SOURCE: 1991 Firebird 305 V8 TBI won't start

ok, here goes, i also have a 305 tbi.. i know it sucks to reach things on them, but you have to know how... i have headers on my bird and that gives them about 2 mm of clearance for the bolts, and i recently replaced the heads and alot of gaskets and such..
The front spark plugs you should be able to reach from the top, but for the back plugs and wires you may have to jack the car up and come from the bottom.. (the only way) .. now on to the timing.. remove the distributor cap and you will notice the rotor bug.. next you will need to remove the number one spark plug..(closest to front driver side of car) now put your finger over the spark plug hole while you have someone crank the engine.. you will be able to feel compression.. when the hole pushes your finger back with air, notice which direction your rotor bug is facing and make a mark.... this approximation will be where to connect the number one plug wire on the distributor.. put the distributor cap back on hook up the number 1 plug wire to the plug and continue clockwise with the firing order... firing order is written on intake just below front of air filter it shoul be like 18436572 or somethin like that.. after you check, your plugs and wires and ensure good connection. you can take a 7/16 end wrench and loosen your distributor.. have someon cranking and holding gas while you slightly turn the distributor back and forth until it sounds good.. be careful don't turn very far it can cause the engine to back fire and without the air filter on the gas will ignite and cause a small fire... (This could be your only problem because if the distributor is moved at all the firing process will become all screwed up)

SOURCE: Car will not start.Engine turns over but spark plugs willnot fire

I would say replace ignition coil, that might me the problem, otherwise it can be the ecu, which might have some electrical problems not allowing the car to stay running. Good luck.

Getting fuel and spark but will not start

Any codes? how is battery crank power?

Have fuel and spark does nat fire. tried starting fluid still no fire. have spark to the plugs.

It's highly unlikely that your timing chain has jumped .. unless you have been doing work and fitted it incorrectly..?

The chances are that it's a sensor at fault. You can save yourself a lot of time and bother by getting somebody to read any error codes that may be present. Identify the fault first and then fix it.

95 buick wont start

Got fuel? Sounds crazy but you'd be surprised how many times I have poured a gallon of gasoline into someones car to get it to start.

No start condition is the most frustrating problem. More information on what happens when you turn the key would help......but basicaly you need 4 things to make a car start. Fuel. Air. Spark. Timing. Fuel, Air, Spark and Timing are needed to start/run. Asked about fuel, but is the fuel getting to the cylinder? Do you have fuel pressure at the fuel rail(s)? When you turn the key to the "On" or "Run" position, do you hear a whining sound coming from the rear (fuel tank area)? That is your fuel pump priming the system. No sound? Check fuses and relays associated with the fuel system. Air. You need air to the cylinder to make it start and run. Check your air intake and filter. Really clogged and dirty filter? Pull it out and try to start. No go? Put it back (change ASAP) and look for Spark. Spark includes battery. Are there any loose connections to/from your battery? Really corroded terminals? Clean and tighten the connections. Try to start. No go? Pull the spark plug wire off an easily accessible spark plug (grasp the "boot" as close to the plug as possible and wiggle back and forth easily while pulling - these boots and wire connectors are fairly delicate). Remove the spark plug (be careful and dont break it or cross thread it when putting back in) and pop the wire back on it and set the plug on top of your engine (away from the spark plug hole). Have someone try to start the engine. You should see the spark plug fire its tiny bright blue spark. If not, you have found your problem. The problem is likely a bad coil, bad coil wire, distributor cap, rotor or a combination of these. If you have spark, then it has come down to timing. There are lots of things that affect timing in modern cars. There are a couple of sensors that jump out - Crankshaft and Camshaft position sensors. These will generally quit working while driving and you will likely notice the problem beforehand with it running really rough and getting crappy mileage, and the check engine light will come on and give you all kinds of hints. IF you turn the key and nothing happens, it might be a broken timing belt, but again, those usually fail under working conditions. It is possible (rare) the timing belt slipped/broke when you last shut off the engine, but I would point at the other 3 things first (Fuel, Air & Spark). Hope this helps. Good luck.

Wont start. it trys to just wont fire over. has spark and fuel.

Without knowing what kind of car you have...It may have jumped time? Timing belt or gear?
You have spark and fuel, Just might be at the wrong time? See if #1 piston is at top when #1 plug fires.

Caprice 5.0 won't start but turns almost over

you need three things, fuel, air, and spark. the fuel and air should be ok. Let's check the timing. Oh. are you sutre the firing order is right with the wires? Ok, they are,right? Now set the timing marks on front of engine to match up at 4 degrees after you bring #1 piston to top dead center.on compression can tell when its on compression stroke by removing spark plug and bumping the starter untill the piece of tissue you put in the plug hole blows out.then once the timing marks are lined up,check what wire the rotor is pointing at. If its close to #1, turn distributor slowly either way untill you hear a spark jump or pop. Lay #1 plug wireon the engine with the spark plug stuck in it. When the spark pops, the plug will fire at the timing mark setting. put plug back in, minus the tissue, put the wire back on and sng doe your distributor. the firing order is casted on the intakke manifold. Like 18436572. Going around top of dis cap start at the wire you know is #1.and in the direction the distributor turns make sure wires are in that order on your manifold.don't forget to secure the distributor cap..I this distributor has points the dwell/gap will have to be set while running with an allen wrench and dwell meter.at32 degrees. No points,no ptoblem. no setting. button it all up and look around for loose anythings, especially tools on top of radiator and light it it up. Final timing should be set with a timimg light. Any problems , I'll be on the puter bot noon o clock my time. Good Luck.
