First ill tell a little about the motor, fresh motor with street port, all blockoff plates installed, gt 35/40 turbo, tial wategate, rx-7 store ultimate fuel system (1000cc prim. and 1600 sec. with resistors intalled.) running apexi pfc premapped for what i have. new plugs and wires, sx regulator running 55 psi,

- any ways the car starts but shuts off after 5 seconds or so and im stummped.

the guy who did my motor said he fixed my harness but when i opened it looked all boogered up so i had to fix a lot. the one thing i cant seem to figure out is this blue plug that sits next to the ecu, and in it is the black and yellow wire that power the injectors, i had to jump power to that to make them work, it seems like im missing a plug or something?

so any help at all would be great, just need to get her started and well go from there.

thanks, jay

 

any ideas would be nice im workin on her now

 

Buy a new harness, it isn't worth the hassle. I've seen harnesses with intermittent injector connections, hmmm, I wonder why that car went through 5 motors in 2 years...

 

55 fp is too high
set it to 40 basepressure

 

got the car runnin now on the stock computer with 40psi fuel, runs like **** probably cuz of the huge injectors, runs so rich u wanna pass out. ideas?

 

yeah talk to jason at the rx7store and see if you can buy or get a map cause he has the same injectors

then put back your pfc and put it in

if you cant keep the car running at all it could be that you have the wrong option selected for the voltages...it could be a million things but a really screwed map would do it and I cant believe it starts on the stock ecu with 1000s instead of 550s
