Fuel pump problem-no three second prime or purge
#10
Quote:I took off very quickly from a stop. Car stalled. No lights Cel or otherwise.
(i edited DEL to CEL) sure CEL dead, the fuse blue, ecu is now dead.

Quote:Checked fuses. IG-coil fuse was blown.
Relays chattering.(that symptoms means ECU sees power feed overloaded in fact voltage power is below 9vdc. bad.
Quote: Replaced fuse.
Fuel pump would not energize.
I ran a switched and fused wire from battery+ to pink+ black wire to get me home (way out in the woods off road )
you hot wired pin 4 on FP relay
will if that action touched pin 3, the ECU is blown up, Q106 is not blown the kingdom come. easy as eating cherry pie, hot wiring the relay,
the battery has 500 amps on tap, so can blow .1amp transistor , 5000 times over. BOOM silicon is now carbon and air.

id test the pump FP relay removed, hot wire the pump and measure its current, if over 4 amps, the pump is bad and was the day one failure cause.
and blew the fuse.
hot wire the pump very carefully even pull the ECU connectors first, to protect the ECU. (all connectors on this car are lever locked, do not force connectors)
