Hi Danny .

When trying to start does the tachometer (rev counter) work, when cranking the engine the Tach should show 250+/-50 rpm.

If this does not work replace the crank and cam sensor .

Is the check engine light ON when you have the engine running ? If yes check for malfunction codes with a code reader this will help you diagnose the problem .

If you can get back to me with the codes for further assistance .

If you still need further assistance then please don't rate, just get back to me with the reply button, and I will get back to you or inform another expert to assist.
Also there is no extra charge after accepting .
Kindest regards Greg
