also if you didnt reinstall the crank sensor correctly and leave the gap too large betwwen the sensor and reluctor then you will have this problem

Faulty crankshaft position sensor - Crankshaft position sensor harness is open or shorted - Crankshaft position sensor circuit poor electrical connection - Signal plate may be damage - Starter motor may be faulty - Starting system circuit - Dead or weak battery

Customer: replied 3 months ago.
What means "Crankshaft position sensor harness is open or shorted" & "Signal plate may be damage"?
Expert:  david craig replied 3 months ago.

yes. i would check the signal plate first

Customer: replied 3 months ago.
How do you check the signal plate?
Expert:  david craig replied 3 months ago.

1. Install the crankshaft position sensor to the cylinder block front case.
2. Tighten the crankshaft position sensor mounting bolts by hand.
3. Tighten the crankshaft position sensor mounting bolts to the specified torque.

Tightening torque: 8.5 ± 0.5 Nm (76 ± 4 in-lb)

Expert:  david craig replied 3 months ago.

you need to pull the sensor back off, pull the crank gear off and inspect the plate. make sure it isnt bent or otherwise damaged

Expert:  david craig replied 3 months ago.

you might want to inspect the wiring harness first, first up from the sensor all the up to its disconnect and look for any damage, pinching etc...

Expert:  david craig replied 3 months ago.

whats it say about the immobilizer system?

Expert:  david craig replied 3 months ago.

you have to have an immobilizer indicator

Customer: replied 3 months ago.
The engine immobilizer system prevents the engine from starting and immobilizes the vehicle if a key other than the key registered for that vehicle is used in an attempt to start the engine after forced entry. The engine immobilizer system consists of the ignition key, the key ring antenna, the ETACS-ECU (immobilizer-ECU), and the engine control module (ECM) <M/T> or powertrain control module (PCM) <A/T>. It has these functions:The system is designed to be maintenance-free because the power source for the transponder is supplied by the ETACS-ECU (immobilizer-ECU) via the key ring antenna. Two ignition keys are provided, and up to eight keys can be registered to one vehicle (one receiver) as needed. There are 4 billion combinations for the encrypted code. In addition, one part of the code is changed each time the key is switched on, which improves security by preventing theft using a copied encrypted code.
Customer: replied 3 months ago.
but where is the indicator?
Expert:  david craig replied 3 months ago.

im looking....

Expert:  david craig replied 3 months ago.

if it was the immobilizer you would have a code for it. you're chasing a ghost. check for spark and make sure the fuel pump runs when you turn the key to run.
