ok i have come across this problem when doing engine swaps to my car.
these problems on a number of ocations have been cured by different means.
1. check the fuses at thebattery, make sure they havent blown, 1 of them controls the fusebox/ecu side of things
2. check/replace the fusebox
3.ecu pats has kicked in, you need to get the correct key for the correct ECU
but does my 130ps ecu fit onto the rk wiring? its a gti car but the ecu is from a 95 130ps with internal pats and edis same as the other ecu's. i have all the right keys for the 130 ecu but not the gti one
so i found out that my cast ecu is plug and play with the gti wiring loom. so ive still got the same problem. i check all fuses and relays and replaced the fuse box already. everything is fine. theres even 12v going to the relays that controls ecu and injection but the relay doesnt actually click. theres connection between the other side of the relay and ground so the circuit is there but not being made. maybe i should earth the whole car myself to get a decent earth track because i heard escorts earthing is a bit tat. maybe a bad earth is my problem in the first place but it seems strange how eveything electrical is working.
it just seems like the ecu isnt getting or sending the right feeds as everything else is running.
wierd. im going to try and test all the connections and if i cant find it get an auto electrician. dammit.
