SUV sat for a weekend, come early morning Monday to go to work. Started up just fine came to temp, windows defrosted. I am about 1/2 mile from home and it goes almost dead, barely running and then dies. Try to restart and it dies almost immediately. Finally after about 10 tries it runs rough enough for me to make it home (full throttle never gets above 1200 rpms). And it hasnt started back since. I troubleshot (is that a word?)to the best of my ability. Fuel pump is working, can consistently produce 62psi on the fuel rail after pressure release. No obstructions in air delivery. Get to spark and there is none both banks. Coils are all getting power with switch on and cranking. I surely thought the Crank PS went sour and fought that for about 2 hours with my gorilla hands in that tight area. Still no spark. Not sure where to go from this point. Any advice would be much appreciated. Thanks!
