Hello,
Ever hear of a crankshaft position sensor?
Expert:  Virtual Wrench replied 1 year ago.
Hi,
The CKP sensor is located on top of transaxle housing, above flywheel, near corner of rear exhaust manifold.
Flywheel contains 3 sets of slots areas near starter ring. Each slot area contains 4 slots in each set. As crankshaft rotates, CKP sensor generates pulses due to slot areas on the flywheel.
When solid area on flywheel aligns with bottom of CKP sensor, voltage decreases to less than .3 volt. When slot area on flywheel aligns with bottom of CKP sensor, voltage increases to 5 volts. Switching of the voltage generates pulses. These pulses provide an input signal to the Powertrain Control Module (PCM).
PCM uses input signal to determine crankshaft position. PCM uses input signal along with other various input signals for controlling fuel injection synchronization and ignition system.
Replace the CKP sensor and i think you will solve this problem!
