Hello everyone.my first post. Bought my 2002 s10 2.2L last summer drove it for two weeks then it lost power during driving when I started it back up it backfired but then was able to get it home after that it would start an then die sitting in idle. Replaced a crankshaft sensor an had it reprogrammed after install now it ran good until we lost power again driving.so we replaced camshaft sensor. Oil change.fuel filter.fuel relay. Battery.starter. an another crankshaft sensor. Thermostat. Checked all fuses. After gettin fuel filter on it fired rt up after driving it just the other day drove it for 30 min to let computer realize there's a new crank shaft sensor an camshaft sensor codes came up with those two sensors again won't crank at all now some things draining the battery so I took out after market stereo an I leave positive off battery since it's a new battery.acts like no power at all but then when I disconnect battery then hook it up again an try to crank it will crank bit nit turn over getting 55psi fuel pressure.
