Mk1 RT Fuel Relay Problems

[Djw Dave]

Ok after refitting the engine we tried to start it this evening

basically with everything connected as it should the "fuel injection locking relay" starts clicking wildly along with the fuel pump itself, no spark and car wont start

if i remove the fuel injection locking relay and leave just the fuel pump relay, it clicks wildly instead

if i remove the pump relay and leave the locking relay the relay clicks once, then the fuel injector starts buzzing loudly and sprays fuel into the inlet, still no spark tho...

if i leave both relays inplace but remove the pump fuse or unplug the pump itself under the rear seat i get nothing at all, no clicks or buzzing at all

the pump works as ive put 12v directly to it and it spins up nicely and u can hear it pressurise the lines etc

any ideas?

Never mind sorted it myself! Dodgy earth on the starter motor!

was thinking might be some fundamental electrical thing but totally didnt have a clue what to say lol glad its sorted.

It just seemed random as the starter was turning fine but the fuel was being pumped and no spark so all very random. But its all running now, started first time
