:duh:i have a s13 hatch with a redtop. its not starting. i thought it was the ignitor because i was getting no spark at the plug. i checked this by pulling off the coil sticking a sparkplug checker in it and the other end on top of the plug. the bulb did not light up.

i double checked and re installed the cas. using the fsm and all links and notches lined up. in getting fuel i can smell it. the plugs were also a little wet.

im checking for power and ground at the ecu. some of the pins aren't getting enough power. for instance pin 4 on the ecu(62) is main relay ECCS and calls for 12v with ignition on no start. im only getting 0.86v.

and another example ecu pin connector 13 is power ground (ECCS) and ground should be under 1 ohm. my dmm is reading 32.2 Ohms.

is my ecu fried? and suggestions. im working on it as we speak.

im checking ecu pin36 IGNITION. its getting 11.46v with key on engine off.

when i crank it it drops to 6.4v to 5v.

normal or not?

pin 4 is only getting 0.8v with key on engine off. its supposed to get 12v.
