What triggers this relay ?
Also where might I be getting a short circuit at the glow plugs?

My wiring is a little strange as the car was a prv
Swapped with h a d24t from a 760 with some components from d24 240 also

GP relay triggered by the temp sensor screwed into the rear of the head, hiding under the rear cam cogged gear that drives the IP belt. Actually located more inbetween the cam gear and the IP rather than directly under the cam gear. Disconnecting the temp sensor should fool the relay into giving max GP time.

Hard Starting sticky, specifically the Glow Plug Section

More on GP testing

There are two different glow systems it could have depending on what cars those parts came from. Post some pictures of the relays and setup and we'll help you identify what's there.

Short circuit could be a shorted plug, or the glow plug bus insulation missing somewhere and touching something. The plugs draw 12+ amps each though, so if you're concerned there's a short because it blew a 30A fuse while testing it, that would be normal. Do a visual check for shorted bus or supply wire, and if OK, start checking the rest of the system out.

Default Got it

Replaced return lines from injectors
Burped the cooling system
Checked for shorts found none
Pressurized the tank and forced fuel untill the return was free of bubbles
Charged battery and jumped with another car and after a bit of cranking 4-5 cranks 15-20 sec each it fired and now starts easy
Thanks for the help !
