Hi, dropped a mk5 rs2000 16v engine in my mk 4 escort xr3i cab. Wired the rs2000 ebgine loom via 2 yellow relays. One as an ignition relay n one as an injection relay. The way ive wired it will prime the fuel pump and make a click in engine.
Ill crank it over n wont start but when i remove key from ign barrel the fuel pump stays on permanent, until i remove fuse on permanent feed to relays. Ill then plug fuse back in then itll do same over again.

The way i can get it to run is by bridging switch wire on relays to fuel pump wire on relays.
It will fire up and run mint but fuel pumps on permanent with switch wire.
Then same happens again, on removal of key engine carries on running, even if i pull all positives off battery until i remove that fuse on relay feed, it wont cut off??

Any ideas? Its prob something so simple like an earth lol but dont want to damage ecu, pump, engine etc
