new to the page. wanting info on sr20det engine conversion for s13

Recommended Posts

hey peeps. so im new to the page. i recently bought an s13 which has had an engine swap from ca18det to sr20det. the guy i bought it off had not finished the wiring part of the conversion so im trying to figure it out now. so iv bought the new engine loom and sr parts needed and have connected up the loom near the headlight. now i still have no power to the essentials. ecu is getting power but when turning key to start theres no power to starter to crank it, no power to fuel pump, injectors no pulse to coils. nothing. iv been trying to find info on it for the past week but not having much luck. any info would be good. i wana make sure i have done it correct

Did you conect the 2 looms together? There is a loom for the starter alternator and theres a loom for everything else. When looking into the engine bay there is 3 plugs to the right of the bay behind the headlight. Check there connected and have a pulse.

And the last thing is check under the dash under steering wheel he hasnt cut any cables. Besides all that i couldnt diagnos the problem without playing with it

Finally got it sorted out and running. Worked out that all the wires near the headlight were correct but the guy I bought it off messed around with the loom near the main fuse box so had to re wire a few things. But after working that out I re wired and works fine now :)
