Okay so I am doing a ka24e swap in a datsun 720 I followed the wiring on this page:
http://community.ratsun.net/topic/537-h ... -anything/

I wired it how it said except the fuel pump positive i noticed was pin # 104 according to the pinout and # 106 wasn't black and pink so i assume that was a mistake.

The starter wont engage when I turn the key and my fuel pump runs while the truck is off and turns off when the ignition is in the on position. I believe I am using the correct relays they have two 87 pins but none are 87a so I believe it will be for sure a normally open relay? Not too sure where i could have gone wrong if anyone has any suggestions i'll listen to anything.

Thanks
Nathyne

Okay well i fried one ecu and wiring harness somehow. Replaced the ecu and the wiring harness and wired it again. Fuel pump now runs as it should (turns on runs until there is pressure then turns off) but i have no spark or fuel. Any ideas?

Well I am pretty much out of ideas now.

Checked my wiring realized I didn't connect my cas and other sensors back to the relay just connected the pins did that still not starting
CAS code 11 is still there
voltage at connection a and continuity to ground at d
Coil pack is slightly out of spec 1.2 Ohms (should be .8-1.0) and 9995 Ohms (should be 10000) would this cause a no spark situation?
Don't have a friend near by to test if there is spark directly at the coil is there a way to check the voltages from the connector?
Even added a manual switch for the clutch/neutral switch hoping that would work but nope.
running out of ideas I need this truck running by Friday or else I need to buy a temp winter beater so any opinions would be great!
