Compression is good, timing is spot on, have spark, Kpro was tested in a friends kswap, 43 PSI at the rail. But for some reason the injectors are not firing, pulled the rail and tried them in he open nothing plugs don't even remotely smell like fuel. The injectors are 270cc EP3 ones from a junkyard and were out in the open but looked "ok-ish". Set to 270cc in kpro also the little ground that goes to the VC is tight

 

get a probe and check singal at the injector plugs.

 

Going to get one of these $6 test lights tomorrow and probe the coloured wire side(??). .

 

Yea definitely an electrical issue. Make sure they're getting voltage

 

Yeah I was gonna recommend a dmm but the voltage probably isn't enough to register. Or I never used a dmm for that,

 

They're getting power and after switching the MAP and TPS plug it came much closer to firing. However I still feel it's being starved of fuel, the plugs do kinda smell of fuel but not nearly what they should. Killed the starter trying to get it to turn over, so can't re-check compression but it should be good still, timing checks out. NO DTCs in kpro which is "good". I'm waiting to hear back from a friend if he can find his old RSX injectors. Any other suggestions are welcome, as it ALMOST turns over but something is still missing.

 

ect?

 

\Picked up some brand new ID 1050X injectors going to install them soon. Botho2 are disabled in kpro for the time being as I have yet to wire my wideband to the Kpro. Does this sound like an injector issue to everyone? I have timing, compression(i'll x2 check), spark, 43psi at the rail and the kpro ran a car 4 days ago.

ECT=engine coolant temp sensor? I have that hooked up via the conversion harness and the one that the ECU reads in there too.


New thought: While i'm not getting any codes for it... the thought of a bad crank sensor or cam angle sensors has been crossing my mind. TSX block w/z3 crank sensor and a z3 head with the cam sensors in in, the engine I nabbed the cam and crank sensors off was low km an in good shape.

 

you'll have to test them. FSM FTW

 

FSMs are a lot harder to come by than ppl think. None the less, did some trouble shooting even with the new ID 1050Xs it still sounded the same and comes close to starting. Un plugged the crank sensor and got an instant DTC in kpro, plugged it back same half assed "start". Un plugged the exhaust cam position sensor, didn't even chug or pop plugged it back and un plugged the IN(EX side is plugged in). tried to do it's half assed start again, pulse plates are not broken and appear fine. i'm pretty confident it's the IN CPS, removed the sensor completely and it still sounded like it has for the past few days. going to swap them around tomorrow to see if it's the plug/something in the harness.


ID plugs are EXCTLY the same as the factory colour order, same polarity order too.

 

Installed BRAND NEW OEM Honda IN/EX CPS and nothing! I can unplug them both along with the crank sensor and it still sounds the same. I'm 100% stuck, there is fuel but not enough or at the right time it seems. Physical timing is good, compression is good, 55 PSI constant fuel pressure at the rail, spark seemed fine when I pulled each CP and grounded it on the painted VC. Kpro ran a car about a week ago, pulse plates are not broken ZERO codes.

 

super secret fsm link sent via pm.
cant do it here or bad things happen. 8(

 

Appreciate it brother.


The car starts!!
switched the MAP and TPS back to what it was 3 days ago and it fired right up. Don't think i'll ever know what it was, as I put the 1050x and new CPS in in between that time.



here's the car

 

Looks sweet!

 

uhhh....redo the hood....
