car: 91 camaro z-28 5.7 350 TPI

engine is only firing on the left bank of the engine, so only 4 cylinders, and I have absolutly no idea why. help would be apreciated, ask questions, cause I really didnt know what info to put down, the car is getting spark all the way around, and 40 psi of fuel pressure to the fuel rail, and all of the cylinders have been compression checked.

thanks

 

By firing do you mean running on 4 cylinders? If it is sounds like your fuel injectors on the r/s are not getting signal...Not sure if there is a seperate fuse for each bank or not..Hopefully someone with a little more knowledge will jump in here..
Good luck

 

thanks for the help, I was thinking that maybe the intake ports could be block on the left side, anyone else?

 

there are two fuses for the injectors under the dash, inj1, inj2. one of them is probably blown

 

thanks good idea^^^ ill tyry that
