Question about 2003 GMC Yukon XL
Fuel pump fine. bran new battery. just added 5 gallons of gas to tank. was having the problem and yesterday it started fine plugged up to see if any codes and none. today went ot drive it for first time since thinking that problem was solved and it wont start again..
Someone will need to figure out if you are lacking fuel to the injectors or spark to the plugs to proceed.
You say the pump is fine, have you checked the fuel pressure, and do you know if the injectors are getting voltage and ground pulse from the computer ?
