I have an 04 silverado single turbo that will barely start and floods out while cranking. I have had a base tune done by speed inc until I can get it to the dyno. They claim there is nothing wrong with the tune. Is there something I could have missed?

 

do you have a wideband?

 

Yes I do but I did not have it wired up for the first initial start up. The plugs are getting soaked in fuel so I know it's getting too much fuel. Truck will not start and idle for more than a few seconds.

 

did you swap injectors?

 

Sounds like an injector issue.
Didn't swap to right injectors in the tune maybe.

 

I have swapped to id1000 injectors. I have brought the computer back to the tuner and they reassured me that all the data is correct.

 

MAF or Speed density?

make sure you have the right Map sensor if its Speed density...

 

Speed density 3 bar tune using gm sensor

 

you figure it out yet, maybe bad sensor.

 

No I haven't, I messed with it for a few days before bringing the computer back to the tuner I'm waiting for them so ship it back now. I used a tech 2 on it and all sensors were reading correctly so I'm lost on what to do when I get the computer back. I might have to tow it to them and see what they find.
