A likely problem is water in the carb float bowls. Water condensation in the gas tank can get to the carbs and will collect in the float bowls. Drain the bowls if a drain bolt/screw is present or remove the bowls and dump out the water. Also, is the kill switch on? Is there gas in the tank? Do you have spark? Did the battery go dead? Bad fuse?

97 geo prism. Ran fine yesterday. Today went to


wont crank or?

cranks fast, but will not start.?

did you try jump cables start? off a running donor car, AAA style>?

and had to disconn? what does that mean and what was results? if any.

ahhh, to fix the stuck on blinkers? i get it.

not to fix starting...

blinkers on , key off>?


which engine?

the engine type dictates what wiring car has. (partly)

fix the stuck blinkers first. this implies, either ignition switch failure

or gross wiring errors, hacks gone wrong.

the key swtich does turn off blinker power feed.

My 2004 Chevolet Cavalier was running and started yesterday, but the next day would not start. It would turn over, but not start or run. Just run my battery down, started over, over

Spray a bit of carb cleaner in the air boot, off air filter housing to check if fuel pump went dead. Would be a good idea to check all fuses.

What could be wrong?

I would check ALL electrical connections paying special attention to the charging system. Sounds like a loose connection somewhere if I does it when you bit bumps.

it copuld have gotten flooded and washed the cylinders out from leaking injectors or something unable to diag over internet but before you pay someone to mess with it take out the spark plugs pour a few drops of oil down the cylinders and then reassemble and see if it will start

I have a 99'yzf r1 and I'm not sure what's wrong with it, The bike was running fine yesterday. I got off work today and went for a ride with some friends, I stoped and filled up at a bp and about 15...

Hi sounds like bad fuel, if it was an ethanol blend you bought, it could have a high water content, BP has a fuel guarantee but its pretty time consuming to get them to do anything, especially if it was a distributor site, not owned by BP.
Drain the carb bowls into a clean container and see if you can see any water or contaminants.
If the bike rides reasonably, it might come good on its own, with the next tank full. Make sure no ethanol( so bypass BP)
If you got some free water in your tank most of it will be below the reserve pick up, so the bike may stop completely if it gets to reserve.
Unfortunately if there is water in the bottom of your tank this may require draining the tank. as all the fuel additives will turn this into milky looking fuel that will make the bike run worse.
