Its either the crank or cam sensor. Cracked over head cam? Really

Not likely a cracked cam. Start with the process of elimination. You need 3 key elements for an engine to work properly: spark, fuel and combustion. If its cranking then you already know its getting spark. The thing to look at is fuel. Try turning the key to the on position but DON'T start it. If you hear a slight whine then fuel pump is likely working. However don't stop there. Locate the Schrader valve under the hood on the engine. This is located on the fuel rail. Use a flathead screwdriver and try carefully pressing it in. You should get a nice amount of fuel squirting out. If not suspect a bad fuel pump. Before you try any of this have the vehicle scanned for trouble codes as these can point you in the right direction. However sometimes they only give probable cause of the code(s). You may even need a tuneup.

Thank you for your answers, but still no luck, than crank position sensor checks out and not knowing how to check cam sensor I swapped the pick-up of cam sensor with a known good one but still no fuel pressure

Battery is good but the engine won't start

check to see if you have 12 volts at the pump

Cranking does not = Spark, it only means the engine is turning over unless it starts for a second or two (which Would indicate spark). Fuel pump 'whining' does not = needed fuel pressure, it only means pump is getting power. Neither the crank nor the cam sensors have anything to do with the fuel pressure or fuel pump. They do provide information to the PCM for Fuel and Spark timing. A crank/no start situation can be caused by one of the above input sensors (crank/cam) and they will not always throw a code. 1st step is to check codes. 2nd step check for spark. 3rd step check fuel pressure with a gauge and compare to spec. if low does it start with ether? if yes - then bad pump./good spark...if no - then no spark. If no spark then check Ignition Coil, cam sensor and or Crank sensor....plugs/wires. Mobile auto mechanic, Michigan, 1988-present
