Re: Will not start turns over thinking spark problem...
Turn key to on position do not crank you should hear a grrr grunt sound that is your fuel pump but i think you will not hear the grunt because your fuel pump is most likely not functioning.

EVAP system may be stuck in purge mode flooding engine with gas vapor from charcoal canister . Have you tried the clear flood throttle to floorboard as you crank it over ?
Yes, check your plugs and wires... the throttle body and also check all of your vacuum hoses as well.
Pull one or more of your spark plugs and check to see if they are dry or damp with oil. This could be the result of bad rocker cover seal and or the seals around your spark plug chambers.
When attempting to start the car, if it turns over but no spark, then check plugs and wires, if you hear a clicking noise, then it could be a blown starter motor.
There are a lot of thing's someone could do to make it not start , but they would need access to under hood or inside your vehicle ! don't you lock your Jimmy ?
Does the engine turn over , I mean when you turn the key to the start position does anything happen ? Some people just don't know what I mean when I say this ! Engine cranks no start or no crank -no start ! Are there any lights lit on the instrument cluster , SECURITY ? this will keep it from starting ! Does it have spark at the spark plugs ? Spray some carburetor cleaner into the engine to see if it tries to start !
May be you vehicle won't start because of lack of maintenance ! How many miles does it have on it ? Do you change oil regularly ,spark plugs etc...
It sounds like 1 of 2 problems or both first the temperature control sensor witch tells the computer the ambient temperature outside and as it gets colder out tells the computer to give more fuel the other thing to check is the throttle position sensor that tells the computer what position the throttle is in those 2 things together are like a choke on a carburetor seeing it fuel injected you can't pump the throttle you will flood it so the computer has to do it hope this works
The only matter there should be in the throttle body is air. The throttle body in no way has anything other than "nothing" in it. The liquid you see could be the gasoline you threw into the throttle body.
Getting back to your problem. Do NOT have someone looking down the throttle body while you are trying to start the engine. That person may receive a haircut he will never forget! Get the battery charged. Try to start the engine because even though you think you put too much gas in the throttle body, it may start.
The tricky part. If the engine starts and runs for a few seconds, then you are having a problem with fuel delivery and that is the fuel pump most of the time but not always.. If it does not start at all, try one more time to pour gasoline into the throttle body, hold your foot about 1/2 way down on the pedal and then try again to start it. If it still doesn't start, it's time to check for spark.
Should have it scanned for blink codes (DTC) before you start speculating on parts you think are malfunctioning, replacing them even if they were just fine.
Even if you don't have it scanned, at least have proper knowledge diagnosing systems using Benrley's Factory repair manual.
Nine out of ten times I still have to glance my manual's pages just to feel satisfied that I did it the right way besides the torque spesifications.
Just my opinion, geustimating is long gone and replaced with a system that tells you it's about to break or it's gone, regardless if it's an electronic or mechanical part.
if u start an rx8 without letting the engine heat up fully before switching it off then it floods the engine with fuel, a rotary engine problem, ring the dealer and they will be able to sort you out, is costly though... ALWAYS LET THE ENGINE FULLY WARM UP! before switching off!!
also rev the engine to 4000rpm and turn the key with foot still on the throttle when turning the engine off, to prevent flooding
The throttle position sensor is most likely bad or it just may be the throttle cable but I think it is the Throttle position sensor it is located near the throttle valve follow the throttle cable to the end this is where the throttle valve is and the Throttle position sensor is located near the throttle valve on the opposite side it will have a plug going to it and it is held on with two torx head screws purchase the tools and replace.
Ok...you mentioned that there is no spark coming from the coil when it's in no start...Is there power from the alternator going to the coil? One other item...If the timing chain is worn and stretched, it is possible that the cam sensor and crank sensor are out of phase with each other, just enough where a temperature difference will change starting ability. One question...while in no start, have you tried changing the throttle position while cranking to see if it lights at part or 3/4 throttle?
