s14 ecu relay nightmare help

[jdmwill]

ok here's the problem i made a rookie mistake and im paying for it dearly. i've done this a thousand times with out a hitch and never had a problem. i was wiring in a z32 maf in and inverted the wires. so the ecu and harness got fried. so i purchased a new 95 s14 ecu and harness installed it and nothing as soon as i turn it to ign the ecu relay gets tripped and buzz.

what i've done so far:1.de-loomed the whole harness2.continuity test on all wires3.check all the relays4.fuses everything

please nico your my only hope....

So you're saying that the ignition switch is turning the relay off instead of on? It sounds to me as if the relay is being held open for some reason by some line feedback and when you apply the ign switch power, it's causing the relay to open back up.

Double check your MAF wiring, first off. The Black/White wire going to the stock unit is powere by the gated side of the ECCS relay. You could have some voltage feedback coming through that line that's futzing your ECCS relay up.

sorry what happens is the relay buzzess when the ign switch is at the on position making it cut off power to the ecu. thanx for replying brother.

If it's buzzing, you definitely have some feedback going into the relay.
