Your getting a steady 40 PSi when you flick the key and the fuel pump is on aren't you?

Swapping to 850 primaries was a big no-no. And then 1680 secondaries.
So far behind the current use of better injectors.
You did not do your homework.
Pull out those 850 and install IDs 725s or 1000s.

Since all went bad doing the injector swap, that proves the error area is just that.

@thewird naw when i turn the key on the pump primes but when it shuts off the fuel pressure drops to 0, im not sure if i stated that but i think i did =/ while the key still on the ON position

@cewrx7r1 yeah i did my homework got the 1680 with resistors i know they are low imp but hey its all i got =(, and do you think its better if id go 550/1680, cause im really just trying to hit anything in the 400-500 range, nothing more , and safely drive it to a good rotary tuner

But when the fuel pump is "priming" (which really just means its on), the fuel pressure is a steady 40 psi correct? If so then its working fine.

On a side note, you do know your 850 primaries are low impedance as well correct? Or did you use the stock 850's.

@thewird: when i turn the key ON fuel pressure guage reads 40 then drops to 0, i leave the key ON, it doesnt hold the constant pressure

Yes, that is normal. When you flick the key, the fuel pump comes on for 2-3 seconds then shuts off. When it is on, the fuel pressure is stable at 40 psi. That is what i ment.

sounds like one of the primary injectors is not firing, bad wiring or bad injector clip. could be a stuck injector also. were the injectors serviced while they were out?

I'm sub-500hp with a BW S366 with all bolt-ons, and I'm using Injector Dynamics 725 primaries and 2000 secondaries. With my VERY conservative tune, I'm still reaching high duty cycles.

Did you change the map to a 550cc one? Try the stock base map.

I'm going to get flamed for this, but throw the apexi in the garbage. hahaha hate that thing.

your problem is in the map, go on your desktop and look closely at any basemap and compare it to the map you have in the apexi.(I assume you have datalogit?)

A friend had similar problem, make sure the map was uploaded properly.

Something I just realized. That BDC base map you posted is set to use the GM 3 bar map sensor. If your using the stock one, you would have to change it back.

and sometimes it's best to just save your $ and pay a shop to do the work.

put the 550's in, intialize the pfc and replace your spark plugs(i do not care if the old ones are sparking or not) and try to start the car. the 850's will flood a borderline engine, and i semi recall your engine being on its last legs.

The answer to fix your problem is already in this thread and yet your blaming ECU's instead of just making your car work. You keep ignoring what people are telling you and doing your own thing.
