car is a 99 Civic DX
motor is a obd1 b18c1
walboro pump primes normal.
obd2b to obd1 jumper harness to chipped p28 neptuned

the motor was rebuilt and ran great in my old EJ2 coupe. currently has about 5k miles. everything is still "fresh"

im pretty confident i hooked up all the sensors correctly and pinned up all the extra plugs and wires i needed to run (stock harness, i had to add vtec wires). i followed the ff-squad website write-up and i had help in another thread i created. you can look at that thread here: https://honda-tech.com/zerothread?id=2203580

the car has spark. fuel pump comes on. all 4 cylinders and plugs are bone dry = no fuel. the only code the car is throwing is a #10 which is IAT sensor. replaced the sensor, but no luck there. car cranks over fine, but just wont kick on.

i went back to the ff-squad instructions and it said something about an "immobilizer" (IMM) unit. if i don't remove it my car wont start. i had no clue what that is. i don't even know if my ECU has it. the moving of the pin from A15 to A16 was done by previous owner as he had a DOHC swap in there and running fine. (after reading i guess OBD1 doesn't have immobilizer feature. should i try swapping the pins back?)

i will check for clogged filter and for any blown fuses later tonight.

here are the ff-squad instructions. thanks for any help in advance.

I don't think they started putting immobilizers in cars til 01

all grounds are tight

checked all fuses today, they're good.

battery has 12v

injectors seem to have power...it's a lil weird though the meter says -11.xxv (yup that's minus) and not 12v. (same meter on my old car read -4.5v for TPS sensor and thats how i dialed it in. it never wanted to go over to the positive volts. it showed normal 12.xx volts on the battery today though...)

i have a friend coming over a lil later today. gonna try his obd2 ecu without the jumper harness. also gonna try his main relay if that doesn't work.

we cranked it plenty times today while tryin to check the injectors but top of pistons are still bone dry.

fuel filter and fuel rail are getting fuel.

swapped the main relay with a running EM1, but still didn't start. i put my main relay in his car to make sure it works and it does.

also tried his obd2 ecu in my car (w/o jumper harness, duh) and the fuel pump wouldn't even come on (with both his and my main relay)

checked the voltage on his injector clips and they were a steady 14.xx....my car is -11.xx while cranking

next step anybody?
