I recently had the P0335 code woes, purchased a new Crank Position Sensor and belts to kill 2 birds with 1 stone. Mechanic did everything...car drove fine for a day or two. I then notice the warm/cold start ups are kinda weak and have to hit the gas on occasion to get it maintain.

2 nights ago,in 4th cruising, step on it...feels a little sluggish, so i back off and step on it again, pulls hard like usual within about 2 secs,the rpms drop to 0 and the srs light pops on. I pull over, and pull codes "P0107+P113" which both relate to the maf. I then try and crank it ...car cranks, but doesn't turn over. Last time i had the P0335 code which popped on in unison w/ the other 2 codes after a few unsuccessful cranks, before I coudln't even get it to crank, car would just click relays.

Below is a quick list of trouble shooting

* Cleaned maf w/ CRC maf cleaner...eliminated the P0107+P113 codes; still no start
*Changed 100mile old spark plugs; no start
*Rotated the motor to make sure the cam gears were lined up and that the belt didn't skip a tooth. Line up perfectly(plate to hand rotate motor was not tight all the way? strange) still no start
*kicked the starter motor...j/k...i hit it a few times...still nothing
* Charged the battery overnight...even when cranking w/ a fully charged battery it still turns slowly, and weak. I might invest in a new starter.
*checked the drivers side harnesses(behind kick panel) no corrosion or anything.

Thanks for any input.

My car is doing the same thing...but no codes have popped. It ran fine last sat. I washed it mid week where I parked it last..Went to start it yest..NOTHING. It just cranks and cranks. Wont turn over and Idk wtf is up. Car has the HKS Vpro. Alot of cars been doing this lately...

 

Yours might be just a fuse, or fuel issue.

 

I should go check them, I'm pretty sure mine is getting fuel, when it cranked alittle the first time I gave it throttle..The next time I cranked it shot out a huge gunshot so I think its getting fuel/spark, just wont turn over. I got it to slightly turn over a split sec. a few times but none actually had the car running... =(

 

i got nothing...i think, which probably wont do much is buy another starter.

 

do you have spark?
do you have fuel?

check both of those first.

if you put a fresh battery on the car does it still crank slowly?

there could be issues with your charging system... alternator or battery can you see what voltage you have when you are cranking it? to low a voltage and the car wont be able to start.

 

with a freshly charged battery, voltage drops well below 12...last time i took notice it was about 6-7volts during cranking,9thats after a good few attempts) battery sits at 12.3-.7 volts.
Car is at the mechanic for now.

 

Mechanic says it's the same sensor thats bad again...Any ideas how a 3 day old sensor goes bad?

 

something in your electrical system is probably frying the sensor, short circuit somewhere?

 

you ould have brought a bad sensor i a store mngr at a parts store and we do have off the shelf part especially when it come to electrical and sensors instead of spending dough on a new starter pull it out and test it

 

Maybe, before the original sensor went, after hard driving i could smell like burn't/melting plastic(i'm **** about the car) ...on the way home of the original occurance...same smell. The thing is, if the sensor is bad the car would not even and it does a little. That would probably explain the car just losing rpms.

maybe...sensor is getting replaced, again(under warranty) They got the car to start w/ new sensor...the starter is bad. Will be buying a new 1 tomorrow. This Kia rental car is killing me. lol

 

update:
Car is back again, brand new Crank Angle sensor and brand new starter! Car starts real nice...mechanic also checked crank clearance to make sure that it's not walking and hitting the sensor. Gonna have to chalk it up as a bad 2nd sensor. We'll see.
