Car has a b18c1 with a chipped p06 for a gsr. Also has an aftermarket intake manifold and fuel pressure regulator(no gauge)

I have spark.
Cranks strong.
Grounds are good.

I recently hit a man hole cover that was sticking up and it put a gash in my header. About a month or two after that I started getting a low fuel pressure cel code after the car warmed up. The car has also hesitated/non ran great since I've had it. I assumed it was the o2 reading more air assuming low fuel pressure so I ignored it, now my car will not start.

AND the car also has a leak that lets water into the drivers side floor (idfk how) and all the non-stop rain the past two weeks there was some water on the floor (main relay seemed dry).

So I checked the joints on the main relay and none look dry. It will click once when i turn the key to on but the CEL stays on and never shuts off even when I jump the service connector (code 0?)

Also tried jumping +12 to fuel pump and injectors from the main relay plug and nothing happened nor did I hear the fuel pump although its stock and probably not as easy to hear as a walbro that I'm used to. I am on my way out to check the +12 to the main relay right now, will report back.

As of now I think it is the ECU. Any other ideas?

afaik if you get the solid cel AND can hear the fuel pump, main relay is good and ecu is bad.

I just went back outside to check spark again, had one spark plug wire off with a screw driver in it and my buddy getting ready to check, car turned over like 3 times and then started on 3 cylinders. I hate intermittent problems. Only thing i did is clean up the main relay and reseated my chip in the ecu.

The car starts fine now but is there anything I can do to try and figure out wtf the problem is?
