Hey yall Im new here so I guess Ill just jump in. I have had problems with this truck since Nov. 2001 Silverado 1500 5.3 I have owned this truck since it was new. It has 212000 miles and had been a real good truck. I started haveing trouble on the way home from NC to Fl Truck just started to die. Slow down, run 600 rpm then just stop. Restart and mess around then finally it would go. I got home the OBD said o2 sensor bank 1 sensor 1 so I replaced it. Then one by one they all went out with in a month. Still shuttin down have to pull over and restart. I checked all the fuses and all the stuff I thought caused it. Fuel filter, fuel pump, coils, wires. etc Well after all the o2 sensors still not helping it said cat's were bad. Bought a y pipe complete. Changed the muffler. And while I was at it, trans mount, all u joints and mid bearing. Didnt help. I got a code a couple days ago along with the multiple cylinder misfire, map sensor and crank sensor. I cleaned the map sensor, and changed the crank sensor. The truck started right up reved good so I let it idle. After about 2 or 3 mins it died and hasnt started since. I have unhooked the battery, done the relearn 3 times. With the turn the key on for 11 mins off for 30 sec three times but it wont start. I think its a fuel problem because it will run if I spray starting fluid down its throat but it just wont run on its own. I found the old crank sensor cracked at the bottom so maybe it did need that. It has fuel pressure at the valve on the fuel rail but not much. Any help would be appreciated. I have been told to take it to Chevy and let them reprogram the computer. But I aint doin that. If I cant fix it, it will just sit and Ill get something else.
