O.K. I got my motor in. Pulled the plugs, cranked it to build oil pressure and blow out any **** inside, shot some ATF in to help compression, primed the fuel system, and tried to start it. Just cranks....no start. So I swapped the plugs for new ones Checked all connections and still nothing...

1. Fans run as soon as battery is hooked up...won't turn
off
2. Inside cabin there are 3 yellow connectors for
computer, 1 white connector and
1 blue one. The blue connector on the old harness is
a 10 pin with 10 wires, the
new connector is 12 pin with 11 wires. WHAT IS THIS
CONNECTOR FOR AND
HOW CAN I MAKE IT WORK? Will that make the car
not start? I USED A JSPEC
HARNESS BTW....


I checked:

-CAS is plugged in correctly. Swapped CAS a known
good one
-Checked spark with spark tester
-Fuel lines appear to be hooked up correctly. Not
binding, looks right. Tried swapping them, didn't help
any
-I'm getting fuel pressure from the pump
-All plugs on engine side of harness are plugged in
-Ground on drivers side battery harness is tight
-2 Grounds under UIM are tight
-Injectors are all plugged in
-Temp sensor is plugged in


Everything looks right, it just will not start. Am I on the right track with the blue connector thing? Do i need to start checking continuity between the injectors, CAS, TPS, etc... and computer?

ANY IDEAS?

Man, I feel for you. THat is the worse feeling, hours and hours of work pulling the motor, installing parts, spending large sums of money, re-installing the engine and the ******* thing won't start. That was my WORST

NIGHTMARE. Fortunately for me, mine started on first crank but then I used the US spec NEW wiring harness from Malloy. Who knows what they do in Japan so I would suspect the harness. The fact that the fan is on sounds like you got a short to the ECU.

I think I have it figured out. I'll know later tonight.

The blue connector from the US harness has to be cut off and soldiered to the j-spec harness to make it work. Cut the extra wire.

So it's working now!?

Yup. Everything is good so far. 40 miles and counting

Good stuff. Thats why KDR put in my motor.

Well I saved $500 on a harness and probably $1000 on the r&r. I'll take a little frustration and busted knuckles to save $1500 any time. Besides the fact that I work on cars all day long, and have access to everyhting I need.
