Bike has been running fine. Changed the coolant and now wont crank. Spins and spins but wont start. No previous problem. Do I have something unplugged or something. Cant figure it out

posted 3 times ,why?
I'm sure coolant was not fully burped out as all noobs do wrong.
and is not good for any engine with upper jackets day ever.

again the word cranks not stated, turns over means zero
the starter must crank and the engine spins crank shaft and engine starts and runs not stall.
Is the IMMO lamp glowing wrong??????? dash lamp theft, IMMO
is the lightning bolt LAMP glowing,.oops,if yes. TBW hard failure
no idea mean what connectors pulled for a water pump.

why not just have 1 post for one car one job W_pump.
P2173
P2173-HIGH AIRFLOW/VACUUM LEAK DETECTED (SLOW ACCUMULATION) means (most times) vacuum hoses not put back or done wrong.
it is vacuum leak it means the MAP sensor reads wrong
and it did not before the job so is now. hoses wrongv.

nobody here can guess what you touched to do this job.
it be like ESP to the MAX


stop using the word turns over,
use crank, starts,and runs or stalls.
all parts there turn, so turns means nothing lacking the 2nd noun
starter motor spins (turns)
the engine crank shaft seen to spin and turns
some say (omg wild) turns over mean firing and running, no that is RUNNING. and sustained.
is the key start position causes the starter motor so make loud GRRRRRGRRRR sound , then good, or not bad.
if the starter does work then then cranks and runs.

i answered 2 posts on topic,
all I have are questions. blind and deaf.

Is the security light flashing on the dash?

Is the battery flat, any noises, clicks? Headlights work and bright?

Has anyone checked for Diagnostic Trouble codes?

The low oil pressure light will come till the vehicle starts an runs ! Explain wants to turn over but won't ? The engine spins over when you turn the key to the start position but won't start an run ? Or when you turn the key to the start position an nothing happens ? If the first one engine spins over but won't start an run , What's missing ? Spark , Fuel pressure , Compression ? Videos on youtube for cranks no start , how to trouble shoot !

That year has about the last ignition module it will run fine until it gets about warm them it dies once it cools it will crank and run fine again for a little bit then out again if this is what its doing change the ignition module it is a big square box under the hood made out aluminum. If you need further help let me know thanks.This was a common problem of sudden stalling of the engine.

When you turn the key to the start position does the starter spin the engine ? The engine cranks no start ! Or nothing happens when you the key to start position ? no crank no start ? Is the anti-theft light lit on the instrument cluster (SECURITY) ? If the starter spins the engine does spin slow or normally ? Is there spark , fuel pressure ? Testing these thing's would be the place to start if the engine spins ! Videos on youtube showing how !

Try puting injector cleaner in ur tank.

Sounds like a faulty crank sensor. Can also be caused by a faulty cam sensor.

when you replace crank sensor the crank sensor is going have to be reprogram or relearn before car will crank.

I had the same problem with a GMC s-15 Jimmy changed the distributor and it has not done it since

Most Likely The Starter I Know We Changed It Is What your Thinking.
I Done 3 In A Row And The Fourth One Was Finally Good.
