My cars been sitting for a couple of months. when i went to turn the key the starter engages the flywheel and turns the crank but either isnt getting any fuel or spark. the car used to start up everytime before it sat. battery is good and fully charged too.

i seriously doubt its the plugs or wires or fuel pump and think its the crank position sensor.

havent scanned it for codes yet. what do you think it could be?

also i changed the headers during this 2 month period so maybe i bumped the connecter for it? if its behind the alternator connectors then im pretty sure i bumped it with something and caused an open or something.

 

Go scan the car for codes and stop creating multiple topics about the same subject.

 

sorry, i scanned for codes and got a p0110 and p0100. i did take the MAF off when i took off the short ram. wondering if i should just replace the MAF and see if itll start.

i forgot to mention i resetted the computer by unplugging the negative terminal for a period of time and still same result. could a bad MAF keep it from starting?

 

The P0100 is your MAF, clean the crap out of it with alcohol based electronic cleaner. If that doesn't work then you need to replace it.

The P0110 code that is your IAT sensor. I believe that is linked to your MAF. In otherwords, get a new MAF and see if that fixes your problem.

 

i cleared the codes with a scanner and disconnected the battery while i went to autozone then came back and replaced the MAF. turned the key with high hopes and still nothing. i have DTC's still but only for ABS. what am i doing wrong???? i really want to get back to driving my lexus...

 

Check the wiring to the MAF....see if there wires aren't cut or stripped. Then test the fuses to the MAF. Something is wrong with the MAF or connection to the MAF to give you those codes

 

i removed the heat shrink off the wires and for the first 7-8 inches of wires starting from the sensor connector looks great. i tested for voltage and got 5 volts in the supply wire. as for the fuse idk how to even check to see if its blown. lol thanks for being patient with me.

wires to the ecu look great too.

which fuse is the MAF ? i checked all the micro fuses with a ohm meter and all were good. idk how to check the medium-high current fuses tho.

 

bump. i really want to figure this out without taking it to lexus. please help

 

After replacing the MAF, did you run the car for codes again to see what else pops up after?

 

just ABS stuff like a speed sensor and another one for ABS but i dont think that would stop the car from starting

 

what's the code?

 

They are; C1224, C1223, C0205

 

For the C1224, read this - http://my.is/forums/f115/abs-light-f...-c1281-483017/

I read fixing the C1224 code will usually fix the C1223 code (which is code that tells your ABS has a problem)

C0205: Left front wheel speed sensor signal malfunction

Did you damage your ABS when putting in the headers? Bang it some how?

 

no i had those codes before i put the new headers in lol. i wouldnt think the engine wont start cuz of ABS codes. i didnt get a code for the crank position sensor but maybe i should take it out and test it for continuity?

EDIT i did bump the ABS pump around kinda actually but nothing serious and kinked lines.

 

Well all you can do right now is try to fix one thing to eliminate that isn't the reason why your car isn't starting.
