Car: Cobalst SS/SC 2007

Installed before problem: OTTP stage 2 kit/ottp heat exchanger/dual pass endplate/hpt tune.

Problem Description: We put the new tune in and tried to crank it. It sounded normal but would not turn over. After a couple tried we heard a horrid metal on metal grind. The starter was shattered. We replaced the starter and tried again. Exact same thing happened.

Question: What could be shattering the starter?

 

What exactly is breaking off the starter? Have a picture of your starter by chance? If its the housing then its not secured properly.
This happened just after your tune?

 

U have a bad ground buddd...stop crancking too much u gonna chocke the engine with gas...oh yeah ur cat will prolly be clogged pretty bad afterwards and if ur catless prepare for a big backfire when it cranks on if u keep on crancking and nothing happens happened to me haha...

 

that sounds like a flywheel issue

 

Thanks for the replies. We will check it all out

 

Flash back to stock, repeat. Starts don't magically break by themselves on a 2.0 liter engine. If you flash a new tune and suddenly it won't crank the tune is at fault, probably severe pre ignition making the starter fight the engine or backlashing the motor, which ruins gear drive starters.

 

Is there somebody I can email my tune to that could check to see if that is the problem?

 

'also the car was throwing some codes. shows the maf at max voltage withing being started. any reason why?

 

post on HPT forums...ill look at it there

 

Posted the tune under V4 engine tuning forum. It is titled "Eating Starters"

In accessories mode the following show

here is a pic of what it is doing

 

apparently starters can't turn an engine flooded with coolent...........have to buy a new engine

 

my grand am started fine flooded with coolant. Didn't like to stay cool though. But hey, I should thank that 3.4 engine otherwise I wouldn't have gotten my balt.

 

Ouch. What was leaking coolant?

 

Not positive as to what is leaking yet.
