Have a 99 Ford Taurus wagon se 3.0 dohc. Wont start. Car was sitting for a year. Replaced the battery, and starter. Got a very slow crank but no where near where I thought it would do. Suggestions?
Cranking is very slow almost like a old dog
barking. I was thinking it was seized but still
can turn main pulley with a wrench, but it is
alittle hard to do. Trouble shooted all my
wiring and all came out good. Plenty of
power to battery and starter. Glass in the
tank and fuel pump works. Was thinking I
may need to use mystery oil to maybe
loosen up heads, and lubricate walls?
If car has been sitting for a while I would remove all belts and clean any surface rust from grooves of the pulleys also spin all pulleys by hand to insure they spin freely. I would also remove the spark plugs and spray just a little wd 40 or something similar in each cylinder. With spark plugs and belts remove try to start it. It should turn over freely. If it does then reinstall the belts. Now try to start it. Again it should spin freely. If not then inspect for what's putting it in a bind. If it does spin freely with starter the inspect, clean and reinstall spark plugs. Also inspect air filter for possible rodent nest. Now try to start it. If it now does not spin freely have someone feel exhaust pipe for air flow as it's being started. Possible blockage there too.
did you check your crankshaft and camshaft sensors
