2003 Chevrolet Blazer Q&A
2003 Chevrolet Blazer Question: Runs fine but slow to start?
I have a 2003 Chevy Blazer 4x4 4.3 V6. Over a period of a few months, the truck is becoming successively more difficult to start - it acts as if it's not getting gas right away. It's been checked a the local mechanic and the usual recommendations have been suggested (most which were already done) It's had (recently) new plugs, wires, fuel filter, and thermostat (mechanic assured us it was faulty, so at <$15, I replaced) The engine turns over just fine, so I don't anticipate any starter/battery/charger issues. However, it takes several rotations before the engine will fire. Once it's running, there no bogging, hesitation, or apparent loss of power? Also, restarts after short periods of being off do not show the same symptoms. I know the fuel pump is supposed to run for 1-2 secs before actual turn over? I don't expect any pump issues, though, as it has no problem once started. ANY thoughts?? Thanks in advance! - Merlin469
Techron from chevron is the best additive and the converter could be causing the hard start problems and until the unit is replaced it could possibly cause a hard starting condition. - hemicuda
