you will have to check to see if the Camshaft/crank position sensor wiring is good

use something to probe the back of the wire and use a multimeter

also check the flex plate of the transmission and see if all the teeth are fine (through the inspection space)

If everything is fine you may have to check the timing chain and make sure it has not jumped or skipped a tooth
