Suspect "jumped" timing belt,if the belt were broken you would have no spark as the distributor is driven by the camshaft, valve to piston collision is unlikely on the era of Camry, but always a possibility, remove upper timing belt cover, rotate crankshaft pulley till timing mark show "0" for top dead center, there is a hole in cam sprocket that will align with a groove in the cylinder head (difficult to see due to the alignment of the strut tower and the tilt of the engine) I use a small drill bit through the cam sprocket to see if it lines up with the notch. If your marks are nowhere near, turn the crank 1 complete revolution as the crank to cam ratio is two to one. You will likely see the belt is very loose, and you may have mechanical failure such as a tensioner or water pump causing belt to slacken and jump...
hope this helps...

Have a compression test done for damaged valves. check that the cam shaft is turning (broken timing belt/chain)

Keep getting P0308 code misfire


A misfire code is set because one of three things is missing or not right: spark, gas, or compression. You checked compression and it's good, equal to the other cylinders? And there is spark on #8? That leaves a fuel problem, then. How does the spark plug look on #8- if the appearance is white, almost a blistered look to the bottom of the plug, that is an indication of lean running- not enough gas in the mixture at that cylinder. You may have an injector problem on #8.

you should conduct spark test in spark plug on high tension wire and compression test in the that plug 6&3 strong gas smell is the result of unburn fuel!!!!but the best solution to bring the car to the expert!!!!!!

I own a 1993 Chrysler Lebaron 3.0L V6 that has been a pain in my backside for 2 months now. It starts when it has more than half a tank of gas but with less it will act like its going to start but not...


Try checking your fuel filter/ or your fuel pump. The lack of weight in the gas tank pushing down the gas to feed the pump because its faulty or clogged could be a reason. It doesnt sound like an electrical issue, but it could possibly be your distrubution system isnt arcing sparks correctly but thats highly unlikely. Since your smelling fuel your more than likely getting gas but somethings up with your Air-to-Fuel Ratio mix. Best thing to do is check steady flow of gas sparks from each sparkplug and a correct compression, who knows your cylinders may have faulty rings and you have no compression to run. :D Hope this helps good luck.

Car seems to be flooded, smell gas and ignition just whirs when trying to start, how long do I need to wait before trying to start again?


I wouldnt start it again till you check the fuel lines for leaks(dont want to burn it up) I then suggest you look for vacuum leaks & do a compression test.pull spark plugs & look for oil fouled spark plugs &smell & observe for signs of raw gas.keep posted

My 1991 honda civic wont start. when i turn the key the engine turns over but it never actually starts to run. it smells like gas. we tried the main rely, but that didnt work either?


The cylinders are probably washed down with fuel and it doesn't have enough compression to start. You need to also check to see if it is getting ignition spark. There are several thing it may be. The quickest thing you can try is let it sit overnight and then in the morning push the gas pedal to the floor and try starting it to clear flood it if it is not starting due to being flooded and cylinders being washed down with fuel.You should pull out a spark plug and see if its wet with fuel. If it is remove all the plugs and dry them out and maybe squirt a very small amount of oil down each cylinder to help seal the rings to bring up the compression. Do not get carried away with putting oil in the cylinders so you dont hydro lock the engine.

2003 Hyundai Sonata with 4 cyl. PO301 error code. Have replaced spark plugs, wires, coil packs, and mass air flow sensor. Replaced air filter due to heavy gas smell. Car was starting after tapping gas 3...


P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.

My car is over heating and there is water or gas on one of the spark plugs


DO COMPRESSION TEST SOUND LIKE BLOWN HEAD GASKET OVER THAT CYLINDER WITH WET PLUG.IF THE PLUG HAS GAS ON IT.SMELL IT IF IT IS GASOLINE ON SPARK PLUG YOU COULD HAVE BAD SPARK PLUG, YOU COULD HAVE BAD DISTRIBUTOR CAP AND ROTOR AND SPARK PLUG WIRE COULD BE BAD.

Car wont start starter turns fast but dont start as if out of gas.i have gas.


If the starter is turning fast you either have no fuel getting to the injectors or no spark to ignite the fuel. If you smell gas coming out of the tailpipe it's probably spark related. If you smell no gas coming out of the tailpipe it may be your fuel pump or a clogged fuel filter. Check the fuel pressure.

Engine turns during starting but will not fire, very strong raw gas smell when trying to turn over


Ok..it sounds like you are getting good gas...but you have to check and see if you are getting spark...and compression...But check all your fuses first...and have someone crank it over with the Dist. Cap off, and make sure it's turning..dont stand to close while doing this..and if it is not turning...you probaly popped the timing belt....

Everything turns on and the car will turn over, and over...but does not start. I can smell gas, so I don't think that it is the fuel pump as i had it replaced. Its getting spark.


ir its getting spark and you think its getting fuel the only other things to look for is for fuel injector pulse, that is that the fuel injectors are actually pulsing the fuel into the cylinders. and compression, a compression check will verify the mechanics of the engine are running properly look for a reeding of about 125-150 with the first hit on the gage being over 50psi.
