I have a 1988 GMC crewcab with a 454 tbi.
It run fine until one day it was idleing and run out of gas, I just shut the key off and decide I would put gas in later. A month later I decided to start it up, so I put gas in the tanks and tried to start it, but now all it will do is turn over. No fuel (TBI) or spark.
I'm not familiar with this computer stuff. I did check for codes but came up with nothing.
HELP

. Ensure you added plenty of fuel; otherwise, it will have a hard time picking it up.

. Turn the ignition switch to ON. Wait until the fuel pump turns off. Repeat this 6 times, to ensure the fuel rail is fully pressurized with fuel. Injectors won't work otherwise.

. Check all underhood and underdash fuses with a test light or multimeter:

. Replace Ignition Control Module:

. Replace coil.
