Came home today after going to bank and after a hour of being home i tried to leave but car wouldnt start... when turning key sounds like its trying to but wont start. Scan tool gives no codes please help

 

TOny, I would connect up a fuel pressure gauge and make sure that you are getting fuel pressure (might be able to smell raw fuel coming out of the exhaust if you have cranked it a lot). After that, there is power to the ECU since the motor is cranking. I would need to look at the diagrams for the car to make sure with some of the other possibilities I have in mind.

 

I checked fuses, disconnected batt and checked codes again and got P1108

 

I think that code is related to the MAF sensor. If the car was running fine before that with no other issues it could be as simple as the battery needing to be replaced. I know when mine went there was no warning, like hard to start, etc. Maybe try getting your battery tested first. Hope it turns out to be a simple fix.

 

Car had spark plugs replaced about two months ago as well as one coil

 

Tony, even if the MAF sensor is removed from the car, the computer can still allow the car to run as it will just assume an air flow based on engine RPM. May run a little rough, but it will run.

Check fuse F92 (10 amp). This is what supplies power to the COPs. If that blows, you will get what you see. Also check fuse F36 (10 amp). This fuse supplies power to your throttlebody and all the accessory valves (IMTs, gas tank valves, etc) for the engine. Then check fuse F18 (20 amp). This supplies the main power for the throttlebody.

From there, like I mentioned, verify that you have fuel pressure. If you don't have a fuel pressure gauge, then you can try squirting a little bit of ether into the intake and seeing if the car will momentarily fire. If it does, it proves you have a fuel issue. You would not be the first to complain about a fuel pump suddenly failing. If this is the case, let me know and I can give you more information about swapping the fuel pump.

This should get you going hopefully.

 

Checked fuses also took and had battery checked all were good. tomorrow i will try to check fuel pressure. Next question will my gas hand move if fuel pump isnt working?

 

Having a similar problem, did you figure anything out tonybucks313?

 

Tony, yes, the gas level gauge will move and show a proper indication if the fuel pump is failed. They are 2 different circuits. The only commonality between the two is that they both go through the same plug. If you lost your fuel gauge indication, then we are looking at a plug that most likely came undone.

 

maybe try this. (Is a link to a .pdf file about the fuel pump cut off inertia switch)
