my car keeps dumping fuel into the injectors and causing it to blow out the exhaust with loud shots... all the sensors are fine but engine light is on still and noticed a pool of fuel in the air cleaner box... i was thinking will the computer keep the injector ports open all the time to cause this?? was thinking the computer is bad most likely?

 

sounds to me like 1 or more of the injecotrs are stuck open

 

could be but doesnt the computer usually tell the injectors to open and close
possible that computer not seeing this??

 

whats the code homes that KEY to fixing your issues

 

well i put it on a snap on scanner and says exhaust is running lean which it isnt... theres a brand new tps sensor and o2 on it...the maf sensor running normal... only thing i can think of thats keeping the injectors open is the computer

 

lol

Computers wont fail and keep the injectors open, the injector driver(in the computer) fails and the injectors close.

Ohm the injectors first. If factory they should be 16-17 ohms, any less than 12 are unserviceable according to GM.

If u find any drastic differences like less than 12 ohm you are looking at replacement.

What you are describing sounds like a cold start injector or injector failure from a leaking injector.

Also check the switch for the cold start injector to see iof it staying on the entire time or comes on and shuts off.

Finally, prime the pump and IMMEDIATELY after doing so block the return and feed lines. U should have no bleed down or very very slow bleed down. If u find any, pull the entire fuel rail and repeat the test with some paper towel under the injectors to help spot leaks.

later
