i'm starting to believe its your fuel pump.

BradEby · 02-09-2012, 03:38 PM

My fuel pump is good though, we dropped the tank and jumped the pump yesterday, it runs fine.

EDIT: I'm still stuck on the idea that it's the relay... Because of the berserk buzzing sound it made before the car started this morning, and whenever i pull one, and put the other in now, it buzzes a little bit and the CEL flickers but once the noise stops, the light goes solid... (still not starting)

Okay, now another bit of info, I disconnected my battery for 10 minutes, re-connected it, and now whenever I turn my key to ON (II), the pump engages for about 2 seconds, the CEL goes out, the relay starts its berserk buzzing, the pump shuts off, and the CEL comes back on solid. (even with the test plug jumped)

EDIT: Should I buy a brand new relay?

No you shouldnt. That's likely an ecu failure. Find a friend with a p61.

I've seen this behavior on old ECUs, the main power capacitor fails, leaks, messes up traces. You can repair the ECU if this is the case and you're savvy with a soldering iron. If you want to look and confirm open the ECU and take a picture of the biggest capacitor near the OBD plugs.

Okay will do later. Just about to hook it up to the tow truck to have it towed back home...

EDIT: I don't have any friends with an Integra.

Did it ever run right with that ECU? Go into VTEC ect? That's for an LS.

MeltMan · 02-09-2012, 07:49 PM

Right. That's a pr4 ls ecu. the capacitor looks good though. The car should at least start on it I'd think

The plot thickens.

i hate to say it, but you're gonna want to find a p61 ECU and see if that works. if it doesn't... i don't know. it's giving me a headache and it's not even my car. i've been googling and whatnot for about an hour now and all i can seem to come up with is: main relay, ECU, and the ground for the main relay. two of these have already been taken care of..

Hmm, thing is, the car was running fine the night I bought it, until it died. What would cause my main relay to sound like the circuit is opening and closing at a million times a second?
You guys have no idea how appreciative I am for your help so far.

MurderedDA · 02-10-2012, 02:13 PM

when i was reading about other people having that same noise as you are describing, they were all caused by bad grounds, and the motor ground. tightening up the ground on the thermostat housing, and tightening up the ground for the motor solved them all. might wana find a better ground than wherever you switched it to.

Hmm, in that case, I may know my issue... There is no ground on the thermostat housing... (I do have a good motor ground, just no ground on the thermostat housing.
EDIT: How would I go about finding out where it is, and how would I replace it? The only ground I re-grounded, was the one directly off the Main Relay harness...

MurderedDA · 02-10-2012, 02:39 PM

anyone reading this, please correct me if i'm wrong. but i believe the ground from the main relay goes straight to your thermostat housing. you may want to re-run that wire. the original wire should be laying around there somewhere where someone forgot to put it back on or it fell off.

BradEby · 02-10-2012, 02:45 PM

Oh boy. My car, is not a GS or GSR, it's an RS... Have I completely screwed up...?

-EDIT: Nevermind, shouldn't be an issue, same engine size and everything. We're re-wiring the ground as we speak.

--EDIT2: Re-grounded, not making a shorting out sound anymore, but the car, when turned to ON, is beeping 6 times simutaniously, and it wasn't earlier... Any opinions?

1point8 · 02-10-2012, 05:34 PM

The beeping is normal. That's your SRS
