the mother of all problems !!!
argghhhhh
Took my car to work, all is good, when i head home it turns on and is just sounding STRAAANGEE!! i mean is like it was only sparks on 1 rotor, wouldnt know the precise way to explain it but it sounds just like a wrx lol. So i work on the car the next day with a friend and he says is the fuel pump. I bought a paxton external fuel pump and still the same problem, had the injectors cleaned and did not work. so i replaced all the fuel lines, fuel filter etc, cleaned the tank, still have the same problem. Bought new sparkplugs and nothing. the car cranks up right away and has white smoke but sounds awful and it does not have power at all, it could be the coolant seals but the smoke smells like raw unburnt fuel...
checked for spark, checked fuel pressure, checked harness connections, tried with a stock ecu, nothing!!
mods. 13b s5 engine, knightsport ecu ,850 secondaries, t04 turbo with external wastegate, front mount intercooler, fuel preasure reg,
has compression.!!! need help pleasee

The first thing to do is get a decent compression checker and check the PSI that each rotor is pushing. Also try to get a coolant pressure tester and pressurize the system a couple of times and see if there's a leak, then rotate your engine counter clockwise after pressurizing few times and see if any coolant comes out the plug holes.

you know what, i should of ,but since the engine is quite new i thought it had nothing to do with low compression, last time i checked it was 110 in front rotor and 108 on back, but i guess i will have to do it, im just wondering if there is anything else i should do, fuel pump had to be replaced so i just took the chance and did it.
just wondering if there was something else to check, to me the problem was a fuel problem but now i just got stuck there

If you have ANY issue with a rotary while it's running, compression checking is almost always the #1 place to start. Especially if it idles like it's on 1 rotor.
