Question about 2001 Chevrolet S-10
just bought this truck and it turns over....but wont start.....has good bat. has started every time till now.
Hi , these trucks are notorious for fuel pump issuse. (I have 2 in the shop now).First check for spark if spark is present then we need to check for fuel.if a presure gauge is avail,install the gauge and crank the engine.if presure increases to 50-60 psi fuek is probably not the issue. now if a gauge is not avail you can remove the air cleaner/snorkle assy.spray some carb cleaner in the throttle body,then try to start if (if it starts for a second the problem if fuel.now if it starts go under by the fuel tank,reach up (from the drivers side and unplug the fuel pump plug (4 wire) have some one crank the engine ande check for battery power on gray wire durring cranking,if battery power is present check black wire for good ground.if both power and grounds are present pump is no good.if now power then swap the fuel pump relay w/ same design relay (in the underhood relay center) relays are also a known issue w. the s and t trucks,good luck Thanks

Crack open one of the fuel injector lines, see if you have pressure, if not you have a fuel problem. Check the fuse, relay and finally the fuel pump. If it has fuel, pull a plug wire, see if ya got spark, if ya dont it's probably the module
