[JOHNNYSTUNTS]

so when my bike (03-04 636) get hot it wont start.. cranks but wont fire up..it roll starts.. im thinking somthin in my harness? but i dunno.. it roll starts.. anyone have this happen, any ideas?

Do bikes have crank sensors? My sisters neon wouldn't start when hot and it turned out it was the crank sensor. But it would also just shut off randomly tho.

check oil level and pump.. is it a new battery? have you tested battery or rectifier w/ multimeter? do you have key ran to your ignition still or did you mess w/ ignition & harness? next would be fuel and fuel pump maybe?

pump kicks on.. ignition hasnt been messed with.. new battery.. it starts fine when its not hot..


shit i just washed it ..now it isnt doing shit..lol..

[SQUINTS]

i was going to mention or ask if fuel was good or if any way water could have gotten in it

Have to confirmed good spark???

If so then the only thing left is fuel....... check and see if the pump gets hot if it still getting power and ground and if it is then check to see if it actually pumping...

That's your problem shouldn't have washed it lol

I had the same problem with my 08 gsxr 600 it wasnt the pump what was happening that the engine was so starved of oil over the lot sessions it cause the crank bearings to wear out so it was pushing the crank over when it was cold and when it got hot it caused it to seize up. The starter would force it to turn over, but ended up popping about 100miles down the road. Don't jump to that just yet check the starter it could just have too much resistance and causing it to not spin fast enough.
