5.3 into Jeepster Commando will not stay running
First off, let me appolizge as I know there are many similar treads out there.
I am at wits end, installed a 2003 DBW 5.3 into my Jeep and had the computer flashed and the wiring harness done by a company out of AZ. Here is what is going on. I try starting the vehicle and it imeadiatly fires, runs for maybe a second or two and dies. Sent the ECM back to tuner to make sure VATS was disabled which he says it is.
Fuel is at 55psi, Noid light pulse two strong flash`s then dies to a very dim to almost out while holding the key and continous cranking. Trottle works, tried unplugging MAF, Checked grounds, replaced injectors with brand new ones (Tuner stated he thought that was the issue) Nothing has helped.
I am disabled, so I hired two different certified mechanics to see if they could figure it out, No change, They both believe VATS is still active.
This is getting very expensive. I am reaching out for help here as my last resort... if i cannot get it to stay running i am just going to part it out..I am out of ideas. Any help would be apprecated. Sorry for the novel...
