I have 1993 Chevy K2500 SUB with a 454 throttle body w/4L80E, 4x4. It won't run. It cranks over great. For some reason the timing chain broke and had a shop replace it, they replaced the computer as well. It ran about 80% of max before the timing chain broke. I drove it about 20 miles at about 30% and it went downhill from there. Now it won't even fire. After sitting for a day it will try to start and quickly floods. It supposedly has the correct timing. Maybe the wrong computer was installed, I don't know. It cranks great but won't fire. Any help will be greatly appreciated. Thank you in advance. A couple of mechanics looked at it and nobody can figure it out.
