On my 04 s10 pickup,one day i left to work. Approimately 1 mile away my vehicle suddenly stalled. I stoppped and it restarted no problem. 10 miles later. Stalled again and unable to restart .got it towed home in hopes to fix myself with some to lil mechanic knowledge i have. Ok..first i checked all plugs and wires. Still in good codition for thy had been recently replaced. I bought an OBD2 TESTER for reason i had check engine light,which had been on since i bought truck used a couple years ago a d no problems. I got code of PO 137 I BELEIVE which co e to find out, bank 1 sensor 2..purchased a new O2 sensor and replaced still no start. Consideri g it stalled the way it did,i now came to conclusion of fuel pump. Before i bought 1 i checked all fuses a d relays. All good. Bought fuel pump,dropped tank and also replaced. Still nothing. Also notice when i turn key to on position i do not hear fuel pump engage before starting....... right now at a loss and confused..... can someone p,ease give me some poi ter and much needed advice on what to do...?..????? Or do i need to just dump it and go buy a ford????

there is a relay in under hood fuse box that could have gone bad. also make sure ground is connected and all grounds are good. you might try spraying choke cleaner in intake and if it fires it would tell you it's fuel. also check to see if your dist rotor is turning if not you need a new dist as the gear is shot. check fuel pressure with a gauge auto parts rent it. shold be 60-66 psi with key on only. try a different relay with a like one in fuse box.
