Problem 5: Engine Cranks But won't Start

Air and fuel filter,tune up,battery and connection ,

turn over or run
turning over is cranking but not starting/running
not turning over indicates seized motor , bad battery starter motor problems , bad ground
turning over is cranking but not starting ---broken timing belt/chain, crank/cam position sensors , no fuel , no spark , no injector operation
best run the fault codes as the fauty will be recorded there

Crank sensor wont have any effect on starting, Cam position sensor would. Also check all your fuses.

To clarify - the engine cranks but won't start, or the engine does not crank ?
What have you checked so far ?

it wont crank even with a good battery (charged) or jump started.
1: bad start

explain more............ what kind of plugs, wont crank????? turn over or turn over and wont start, crank no fire???? changing spark plugs wont stop a truck from running.

No spark, ck the crank position sensor. bolted on engine at the front crank pully. Good luck. unplug and plug it back in to clean the wire connection/

Not sure what yor experiencing . Do you have crank no start or no crank no start? No crank no start is battery and cables issue. Crank no start is ignition , plugs, and fuel.
