[bugek9]

hi guys am new to this forum and i just done my first engine swap. i have a 99 5 door civic 1.4 and i put a 1.8 vtec engine in it and changed the loom and ecu that came with the 1.8 engine and now it wont even turn over from the key i have to put power to the starter and it still wont start . the engine will turn over but wont start can anyone help

Immobilizer? Can you hear fuel pump priming when you turn the key on?

 

[S40TYD]

If its an immobiliser fault it wont let the pump prime anyway?

 

[elvo]

im sure you have to change the fuel pump and tank if you are putting a vtec in a non vtec. i could be wrong though but it does sound like an immobiliser problem

Not true. Once its a fuel injected honda your swapping the vtec engine into then tank etc. is fine

agreed....

if its b18c4 engine from a MB6 then it will be the immobiliser. ive heard this is the one problem with this conversion.
have no idea what needs to be done though in this case :S

happened to my friend with a different swap,he changed the interior loom or something to that effect and it worked no hassle, just said i'd mention it to try help,not sure if tis prob in your case

 

[oscarsayco]

are the grounds connected?
have you try using a OBD1 ecu with a jumper?

Have you power at the starter? Should be +12v at the main feed to starter

 

[bugek9]

ya there is power to starter

So your not getting any voltage to the starter solenoid when cranking?

I didn't think so but maybe its only cutting spark. I assume you pulled a plug to check for spark?

ya i took them out theres no spark going to them

immobiliser doesnt stop the starter - the engine would still turn over - it just wouldnt start.

Not sure if the fuel pump still primes tho.
