Well i'm back again with same issue. 1st specs: 1999 Tahoe Z71 5.7 4 wheel drive. About 4 months ago had same problem . Truck died all of a sudden while going to get pizza. Towed home and found i had ignition problem. So i went thought the gambit. New wires, plugs, Coil, ignition module, Cap, Rotor. The distributor itself was only 1 year old so it was left alone. Put it all back together and fired right up. Drove great, no codes, no missing, great. This truck sits 80% of the time unless i need it to go to home depot or tow something, deer camp, etc. Went out to take it to home depot to get some trim pieces and its doing the same thing. Turns over no start. Did just some basic diagnostic and its not fuel. fuel pressure good and even tried starting fluid. No go. The only thing i can think of is the distributor gear has worn down, everything else is new. I checked the cap rotor look brand new like i put them on yesterday. No arching anywhere i can see. I am a little concerned to pull the distributor cause i messed it up last time and couldn't get it timed right after marking everything and shop even had a heck of time. Any suggestions on where to go from here? I'm about to pull the distributor and see if the gear is worn cause thats all i can think of. it be a shame if it is being a year old Billet one. Any help would be greatly apprciated, i just don't wanna start thowing parts at it again.
