I've been building this swap for a while and finally getting around to cranking it. well i spun it over today with no fuel or spark just see how it sound and it didnt have any problems. but i went back few hours latter to hit the key again and now the car wont do anything.

the fuel pump wont come on anymore when i hit the key and starter doesn't click. weird thing is the head lights don't come on now either but when you turn the switch on all the lights on the dash light up and the temp gauge max's out. before with the key out no dash lights would pop up with the headlight switch turned on. got new battery connectors. its gotta be a ground or a relay cause it was working fine early today.

Another weird thing was when i took the big 50amp light fuse out. the firewall map sensor was clicking when it would make the connection. And at one time for a few turns i was pretty sure that the fuel pump was coming on when i hit headlight switch but it didnt sound like it was getting all the power it needed. its a walbro pump got a decent wine to it.

my grounds i got
battery-core support
battery-tranny
engine harness-thermostat
valve cover - shock tower.

but i just don't how would it spin over fine then 2-3 hours latter have this problem with no changes.

Any idea's is highly appreciated. tommarrow i'll get on alldata at work and see what i can come up with.

 

i've been searching and the fuel pump thing could be the main relay but would the main relay explain my lighting problem? ppl also said the ecu could be a problem. but my ecu is a known good chipped p28. tomorrow ill stick my p75 in it just to see if the fuel pump kicks on.

 

definitely sounds like a main relay related issue. hit the junk yard...

 

so the lighting works through the main relay too? hopefully maybe the main relay got stuck in one position or the other. now their is one BIG relay just hanging down. does the metal tab have to be grounded? i couldn't see any place to mount it i touched it to a ground but it didnt do anything. ill look on hondata today and find the actual main relay.

 

the metal tab on the main relay (when you find it) is just a bracket... where u go to pop the hood of ur car is where it is... its behind that panel tucked up under the coin box on to left. warm weathe ris notorious for killing main relays in efs

 

well it wasn't the main relay. i added another ground from the intake manifold to the firewall. and everything started working again. it was just grounding out where ever it could prolly through the lighting system.
next time ill keep the main relay in mind.
