check battery. check starter.
When you say 'crank over' are you saying the engine won't do anything? First check your battery and then your starter or starter solenoid. You can turn the crank to check if the block is seized or not.
The easiest and most effective way to check a crank sensor is with a diagnostic tester. The diagnostic tester can determine whether the crank sensor is working properly.
Check the crank shaft pulley
Probably need to check the crank sensor (if the check engine light is on) or the fuel pump... I had that problem not too long ago...
A few quick things to check- If it does NOT "crank over": Check the battery and cables. Check the in-line fuses. If it does "crank over", but does not start: Check the distributer, spark plugs and wires. Check the air and fuel filters.
Check for a loose or corroded battery cable Check for a weak battery Check for loose wire on starter or solenoid Dead spot on starter?
Check the Altenator
Check for power to the sensor. check for power and ground to the Ignition coil. If the crank sensor is adjustable, make sure that it is set to the proper gap.
If you mean will crank, but no fire, then check for spark and fuel. If you mean will not crank, then check the wiring and the starter.
Things to check. Does it crank? If not,battery, starter, If it dies crank, fuel pressure, spark, check engine light codes.
