306 S16 immobilizer issue

[Pagalots306]

Hi,

New to the forums and looking for help, I have a 306 XS 18 16v that warped the head, I sourced an S16 engine loom and key, everything installed, engine turns over but she isn't getting fuel or spark.

I can only deduce that the immobilizer is on

The car it came from is now crushed so if it had a keypad it's long gone.

Any advice you guys can give me is really appreciated.

What year is your car & what year is the engine & loom from?
Does your car have a keypad immobiliser or a transponder key immobiliser? im a bit confused as you mention both keypads & changing the engine loom and key, there would be no need to use the key from the other car if it had a keypad.
First thing you need to confirm is if the ECU is powered up or not, are you getting 5v feeds at the MAP sensor & TPS ? Can diagnostic talk to the ECU?
When you say its not getting fuel do you mean the fuel pump is not running or the injectors are not opening?

My car is a 99 V reg 1.8 16v XS, the head engine was ***** so replaced it with an S16 engine, which I bought with loom and key.

I do not know if the car it came from had a keypad, I got the engine loom and key after the car was broken.

Engine turns and has power, so I need to check out the things you listed.

Apologies I'm not a mechanic in anyway shape or form, so I'm a total beginner to this stuff, the mechanic that put in the engine is at a loss to why she won't fire off.

Ok if you have a pic of the 'new' key we should be able to tell if it was keypad or transponder immobiliser.
If it is from a car with transponder you would also need the matching CPH unit to for the ECU to unlock, The ECU, CPH & transponder chip in the key are all a matched set.
Do you know the year of the car the replacement engine came from?
