Did you check for spark at the plugs or just the coil? These rigs are known to burn up the distributor rotor, you have spark but it is not going where it is suppose too.


First of all don't pour any more gas into the throttle body it's not a carburetor that engine is fuel injected you'll burn up the intake if it ignites! Check the spark like and check the pressure in the fuel rail also open the gas door and listen for the fuel pump it'll make a zooming noise if its working keeping in mind the control module could be bad my truck did the same thing


could be a clogged air ( air fuel spark if all three arnt right she wont fire )
