ok lets back up a second here Adriel. looking back over your posts and everything I want to do a quick recap/verify for me so we cover all the bases...
take a look at the diagram for a second. no. 2 relay should be the one under the dash, with no. 3 being the one under the seat. in one of your earlier posts you say the relay under the dash is feeding power to the rear. This isn't really how the circuit works-- both relays have their own power supplies (the one under the rear seat gets juice from the battery) and the one under the dash from the fuse box once the key is switched on PLUS some more from the relay under the rear seat which is also kicked on by the ign. switch. 30/51 is the ignition symbol IIRC, and I think if phil verifies that the "a" on that relay goes off to the pos. side of the battery.
now looking at the internal part of no. 2, it appears that no 3 is the primary and 2 the secondary. 2 will not work if 3 isn't providing juice. You said 86 and 30/51 on relay 2 are getting juice -- ok. that should be correct, so double check. now. it appears that unless the wire coming off terminal 85 on the 2 relay is grounded (ie. engine running, engine cranking, etc) then the internal switch will not close, and 87 will not have juice.
here's the procedure for nailing this gremlin once and for all.
ground the wire in the engine compartment with the key switched on. DONT ground the wire thats coming out of the FI harness! that does nothing. You're not completing the circuit. Ground the wire that is going to the relay. another option is to just run a jumper to the engine and leave that t1 connector connected, and just jam the open wire inside it so you now have 3 wires at that connection instead of 2. current will find the path of least resistance (ground) and complete the circuit.
if this kicks the pump over, then you know that either the wire in your FI harness is broken/open or the internal ground in the ECU is kaput. check for continuity in wire 11 IIRC.
if this DOES NOT kick the pump over, then check the wire between terminal 85 of the 2 relay and the end in the engine compartment for continuity (zero or close to zero ohms of resistance) (you will need to disconnect the wire from the FI harness to prevent a false reading).
if that wire checks out, then it's either the relay or the ground wire for the pump itself. Check the ground wire for the pump. either run a jumper or check for continuity. if it's open the pump isn't gonna run. if that wire checks out, and youve got juice at 30/51, 86, and 85 is grounded, then the relay is SHOT and you need another one.
check the fuse too. _________________ 71 Squareback-FI -- 73 Bay (subaru powered)

Good idea Joe to go over it all. I did this with Father, abet he has a hard time understanding, especially since he loves carbs!
I was prepared to do this procedure, but since you removed the E.C.U. plug, I had yet to figure out how it all went back. So, thought be interesting to spend five minutes, and swap the E.C.U.s. Proceeded and completed, then went and turned on the ignition. I now have a working fuel pump! Trouble is, the battery is at 12.3 volts, and the engine is having a hard time turning. Got it on the charger, and when topped, will try again.

Russ, it is I before E.
I have two, thank you for the offer. However, I need a couple terminal blocks if you have them. Did not come on the harness.

did you forget to plug something back in by chance? Main plug back on the ecu? grounds? relays all back together? _________________ 71 Squareback-FI -- 73 Bay (subaru powered)

I keep checking, and nothing is out of place. That is what bothers me.
One thought I had, would pump pressure bleeding off in a second or two have an affect? I noticed it started doing this last night.
B.T.W., have to drive it down to Kragen on Sunday, to have the charging system checked. If I do not make it, they will not honor the battery warranty. Some new policy. _________________ Please consider I am Autistic, so I process information differently and still working on social skills. Thanks.

the pressure bleeding off after a second or two after you try and turn it over isnt ideal but thats not whats keepimg your engine from starting.
when was the last time it actually started and ran? What have you changed since then? My gut feeling right now is something silly is disconnected.
as for the battery thing thats normal, most places I've bought a battery at do it- if you want or care about the warranty anyway. Is it a hassle? Yeah but presumably if your engines charging system is in order it shouldn't be a problem lol. Tell them its a project car and ur not quite done with the motor work yet. They can usually give you and extension. _________________ 71 Squareback-FI -- 73 Bay (subaru powered)

Fine, good to know. Thought I should not hold back anything.

It was running the morning of 28 August, when we drove it onto the tow truck. It was about a week or two before that, when I was driving it, and the brake line broke. When we got it off the truck, it would not start. The pump would not turn on, that was all.

They would not give an extension, thus why the rush.
I was told by Jim to measure across the coil terminals for voltage, and get none. I have 12.3 volts on either side, 0 resistance on the primary, and 8.28kohms on the secondary. Called Vee Parts, and the owner said it was bad, but there is no warranty. So, I guess that is my problem. Now, if I can find one to test with, I be set. _________________ Please consider I am Autistic, so I process information differently and still working on social skills. Thanks.

that's odd. I actually dont know the procedure for checking the coil. since I've never had a bad one, but maybe Russ will double check on that. The coil not working would certainly keep the engine from running. What kind of coil is it? I've used pertronix, bosch blue, and OG black ones and even an off-brand red one and never had a problem. How is it wired up? _________________ 71 Squareback-FI -- 73 Bay (subaru powered)

It is real easy: just a Ohm meter. You want the resistance between the two terminals (primary circuit) and one terminal and the center hole (secondary circuit). If a circuit is open, 0 Ohms, then it is bad. If the secondary is less than four, it is bad, but will run the car with poor spark.
I want to be sure mine is bad, but I am positive. Russ seemed to agree (called him, even though I did not want to bother his peace) when I asked if he had a good black coil. He thinks he does, and will try and bring it out. Hope no one thinks he is a terrorist with the car parts and tools in his suitcase! _________________ Please consider I am Autistic, so I process information differently and still working on social skills.

I flew to washington with a duffel bag full of all my tools, including a timing gun and soldering iron and my crimper, but all i got was a lame TSA inspection tag that tells me they opened the bag. they;re not gonna bitch about a coil _________________ 71 Squareback-FI -- 73 Bay (subaru powered)

Pretty sure you want to measure the voltage at the solenoid coil terminals of the relay, not the ignition coil. |
