After driving my blazer approx 25 to30 miles it starts to cut out like it's running out of gas and at then itacts like it's getting to much gas. Stop the car and restart it, runs fine for about 5 to 8 miles and does it again. Change fuel filter (3 times) change fuel pump (2 times) change fuel regulator and trottlel position sencer. Ran code at parts store, they told me the o2 sencer was weak. Could this be my problem?

Vehicle quit running all together. I think the fuel pump quit working. 2 nd pump I have put in, drove it for about 200 miles. When I replaced the pump, the new wiring harness that came with it, could I have wired it up wrong to cause the pump to burn out? Did I miss a groung wire? Also I went ahead and changed the 02 sencor. Need help, fuel pumps don't come cheap. Also, is their a cliff near by.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
