Default Injector Pulse? Please HELP Car Wont Start

Ok guys having a problem and cant figure it out...... I have had my car started up and running about 12 times but the car runs really rich which is no big deal has a base map on it....so i let it run for a while the other day let the fans cycle and bleed cooling system...i shut the car off and go home...try to start the car up the next day and it wont start...it will start up for like 1 or 2 seconds and die and thats it??? i am running 1600cc Precision injectors with OEM resistor box and K pro.....i fee like i have checked everything and have no idea where to go next??
Things i do know that i have tested:
-changed resistor box to one i knew would work nothing changed
-fuel pump is priming
-engine does have spark
-engine will run on carb cleaner until runs out then dies
-carrying 52psi of fuel pressure steady
-injector pulse is barely there at best when first cranking but then pulse gets better but wont start

No ground wires where changed and the location for engine ground is on valve cover like hondata suggests
I have a injector noid light on number one and the light is really dim to barely on when i first crank which is when it is close to firing and if i keep cranking it for 20 seconds or so the light gets brighter and brighter and pulse becomes more noticible but still no start?
Injector pulse in (ms) in k pro with key on and not cranking is like 1.6 give or take and when i crank it it goes up to like 6.4 give or take and back and forth
Please help really stumped and wanna drive my car really badly

Install stock injectors & re-map the ecu to determine if the issue is related to your injectors/tuning.

1600cc low impedance injectors can be a handful to tune. I would suggest using an injector driver box with such large low impedance injectors.

Personally I would be using a set of the injector dynamics 2000cc injectors.

for some odd reason tonight i decided to switch my MAP sensor to the stock one and the car started up and ran on first crank?? my brand new Hondata Map sensor may be fried? tried goin back to it after it started and ran and it wouldnt start again??? so i have the stock map sensor in there for now until this is figured out

Sounds like you have tuning issues.
Take the car to a professional tuner.

dont think this has anything to do with the "tune" the car ran before on the hondata map sensor just faulty hondata map sensor
