1994 MAF'less, Brainbuilt MS and harness, AEM wb, nothing else...
Car ran fine for while, no issues with MS at all since install.
Problem started last night.
Denso B577 fuel pump relay clicks non stop with ign on.
Car will crank all day with no start.
Unplug MS plug in stocker clicking stops (no MAF or oxygen sensor so didn't try to start with stocker plugged in).
Replaced with known good Denso B577 relay and still clicks with MS plugged in.
No other relays are clicking.
Car will not start with FP shorted at Diag. box and still clicks.
MS LED's 1 and 3 stay lit, do not blink with relay click, LED 2 stays of even while cranking.
MS has communication.
Resistance reads low on FP relay.
Where should I look next?
Thanks in advance!!!
ps-Scott, no boost solenoid
