Did you change out the plugs, fuel, fuel filter, drain out the old gas, etc. and all the usual maintenance items you should do before cranking up an old engine?
If not, therein lies the issue. You can't just take an engine that's been sitting seized for 6 years and fire it up. There are a lot of maintenance items to take care of before you just turn it over and drive.
Any specific thing i need to monitor. And yes the mechanic said he change fuel pump clean gas tank , no haven't put in spark plugs or wired only change the engine oil.
