So not even a kick over for a sec. Even with a shot of start fluid. Or giving it some gas.

You can buy a curtis sparks tps bypass or make one your self. By taking the wires going from the harness to the throttle and cutting it on the throttle side with room to splice them together.

      So this '02 Taurus with only 87k miles on her starts right up every time multiple times a day except for twice in the last 3 weeks. The first time was 3 weeks ago and the second was today. It happened the same both times. Turn the key and stop to let the pump prime, then when I turn to the start position the engine turns real slow and sort of in fits. Usually when a battery is low the engine turns slow but in rhythm. During my 2 starts the engine barely seemed to turn and the crankshaft rpm seemed to vary. On both starting events I let off the key and tried to start 2-3 times with rests in between. But then eventually on the 4th try it starts right up just as quickly as a normal start.

      I have No clue as to what might be causing this. Only thing I know to do is, next time it does this to put a voltage meter on the battery to see if it's weak. Actually though, because both events the engine ended up starting up like normal that would indicate something other than the batt. Electrically this car is a little odd though. The interior light never comes on when the doors are opened, for years, and then last week it comes on twice when one of the rear doors is opened.

      Pushing the start button the engine turns and will forever without starting. But if I use the kick start it will start with one or two kicks everytime, any idea as to what is going on. New good battery and coil, I'm ready to try anything. It's a great bike, but this is getting anoying. Thank you.

      Exploiting a loop hole in the law, turn 4 wheeler into rev trike
      for a long while I have been trying to get a real 4 wheeler street legal.
      the problem is with the state laws, if it has 4 wheels, its a car and has mega more rules.
      If it only has 3 wheels, its a trike and can be made from cobbled junk parts held together with duct tape and they will plate it
      I wonder if anyone would have insight on changing a 4 wheeler over to a single rear wheel?
      [ I can't afford some $40-60,000 canam or super bike modded into a car, rev trike kit ]
      I want something I can truly ride year round on and off road. Ive rode enough old Honda 3 wheelers that I know I do not want a traditional motorcycle trike. So the single wheel has to go out back.

      Last time I installed a remote start system it was on an old Dynasty whose wiring was too delicate to work on really. A couple weeks after installation it started ok but a ton of white smoke came from under the dash. I uninstalled the entire system and everything was fine after that.

      So in picking out a starter for this '02 Taurus I want something simple that will work with this car well. The start systems I'm seeing are generally designed to do door locking and unlocking, trunk release, etc. As this car already has those functions on a fob I won't be using any function on any future remote start system other than the remote start.

      Can anyone with knowledge of my car recommend a decent but low cost / low extra functions start system that would work well with my Taurus?

      Thanks

      Hi all new to the forum I have a Yamaha Moto 4 champ (100cc?) (YFM100) so I've been trying to get this thing to start for awhile honestly I'm running out of ideas so I'll start with the things Ive replaced and done first it was not trying at all and then I put a brand new battery then the terminals broke so I bought some nice copper ones fixed that up so now battery is got good voltage and all that I have checked all the plugs cleaned everything off so anyway it still wasn't trying but I couldn't get the crank case off and I didn't think using fire was a good idea lol so I busted the crank case off on the left side(if you are sitting on it) wierdly enough the flywheel started spinning I thought it was odd but went with it then I replaced the spark plug still wasn't getting spark so I replaced the ignition coil then it was getting spark next the carburetor was really gross I cleaned it out still wasn't working so I in turn decided just to replace it with a new one so I did (PS I never figured out how the fuel lines hook up if someone wants to help with that to lol) also for good measure put a new air filter so then I pressing the button Everytime I replace something and nothing so then I think what if it's the stator so I have no idea what a good or bad stator looks like but me being to rough I broke the wires on the thing but still no changes the fly wheel spins gets compression (I think) getting spark from spark plug idk other tidbits that might be useful I don't have a clutch line so idk if that has something to do with it I do have the break zip tied in to bypass the safety feature also the throttle cable is in fact broken and I'm working on buying a new petcock for my gas tank because my current one is broke I have very limited money this is supposed to be a project before I go to school for welding and automotive tech so I don't have any money to get a mechanic lol but I'm pretty confident in my ability to do anything u suggest any suggestions are welcome I'll edit and submit pics

      I know this tooic has been addressed by many, I’ve looked through many forums and pages. I did not find anything like the problem i have.
      I have a 2007 Kingquad 450. I have a new fully charged battery. When i turn the key, the dash flashes and seems to struggle before getting fully lite. We can hear a small relay near the computer clicking, i think it is the fuel pump relay. When i turn off the engine kill switch and press the starting button relays click and all the power shuts off, i turn the key off, engine kill switch then start over, power is there. Atv will start with pull start, but not elextricly. if i try to use my winch, all power cuts and engine dies. 
       
      Can anyone tell me what it may be? or has anyone fsced an issue like this before?

      I have a 1999 Sportsman  500, it was running fine, than started to lose power in the winter, I adjusted the idle screw and away I went, than a few weeks ago it died, I have found that i am flooding the engine, compression was at 70PSI and due to the compression release mech. i assume i am good as it compared to the same PSI on a 2000 sportsman 500 i have. i cannot start the atv unless i go full throttle and it starts an runs for about 30 sec than dies, again it is flooded. i ordered a new carb off ebay as i could get one for around $40. put that in same issue, i have checked the timing, (good), valves out of adjustment i adjusted to .006 still same issue, i have found the exhaust lobe and rocker arm to have some wear, i have ordered new ones, but am looking for any other input in this area as well. would the exhaust cam and rocker arm cause the engine to flood? i have used a bore scope and the piston liner has good cross hatching still? any input would be great.
