Bassboy3313 Posted June 30, 2014 Author Report Share Posted June 30, 2014 So I got everything connected and done on the car and it is time to get it running and driving. She cranks very nicely, but of course doesnt want to fire. I figure it is something with the Megasquirt wiring either on the car or in the MS ecu itself. Snap and I are currently researching and working on these bugs. Hopefully will have a nice update at some point here. DrLeadFoot 1 Quote Link to comment Share on other sites More sharing options...
KaiserRolls Posted June 30, 2014 Report Share Posted June 30, 2014 Yay for updates. Edit: is the issue that burnt out capacitor that snap sent me a pic of? Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted July 3, 2014 Author Report Share Posted July 3, 2014 So I ended up removing the VR conditioner and all wiring the PO did along with all my stepper IAC wiring from the MS controller board. I then followed the MS2extra EDIS wiring schematic from scratch and tested it. With a little temporary rewiring to the EDIS module, I now get an RPM signal on my log. AWESOME!!! I now just need to finalize the EDIS wiring, shielding/grounding wires that need it and so on. Then check for constant strong spark to check that side of things off the list.The other thing I have noticed is that Tunerstudio still says NOT SYNCED when I turn the ignition on as well as while I am cranking. Someone said that the car will never fire with it saying NOT SYNCED while cranking and that I need to debug the trigger setup before attempting anything else (3rd post in link below). I have no idea what this means. Any ideas?http://www.msextra.com/forums/viewto...?f=122&t=51475 Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted July 15, 2014 Author Report Share Posted July 15, 2014 Got the EDIS sparking well finally, but now the MS won't ground the fuel pump relay to get fuel to the rail. I've been chasing problem after problem and I think I finally narrowed it down to the small one that will make the car run once fixed. Tomorrow I am going to try and bypass the MS signal for the fuel pump relay and put that relay pin direct to ground. Hopefully I should have a running car. *crossing my fingers* If that is the case, then I know something within the MS unit itself is bad. I've been reading up and it seems that a few bad transistors could be causing MS to act this way. We shall see if the ground switch-a-roo works first tho.

Bassboy3313 Posted July 15, 2014 Author Report Share Posted July 15, 2014 It surely did! The ground switch-a-roo worked so now I know the issue is within the megasquirt itself for the fuel pump relay signal. It was music to my ears until the idle rpm shot up and I noticed a fuel leak at the rail, doh!! I figured the IAC that is currently not being used is open and causing a huge vac leak which would cause the high idle. I went ahead and capped that off for now and should fix that problem. I also ran a new switched 12v source wire to the megasquirt fuse panel and cleaned up the wiring a bit too. As for the fuel leak. I am thinking that the welds from the fpr mount is where its coming from. You can see the spray pattern in the video below which makes me think its pin holes in the welds rather than it leaking from the cup where the fpr nipple mounts inside the rail. http://vid144.photobucket.com/albums/r175/bassboy3313/VID_20140715_133548_828_zps7f6017f1.mp4 http://vid144.photobucket.com/albums/r175/bassboy3313/VID_20140715_133407_674_zps640d113c.mp4 Quote Link to comment Share on other sites More sharing options...
B C Posted July 15, 2014 Report Share Posted July 15, 2014 See, what im getting at, is you purposely held out, until my car wasnt running, to get yours running Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted July 15, 2014 Author Report Share Posted July 15, 2014 It all falls in line, huh? Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted July 24, 2014 Author Report Share Posted July 24, 2014 So I got the fuel rail dye checked and rewelded and still has a leak. This obviously means its something else. After thinking and thinking some more, I realized that the stock cup that the FPR o-ring goes into was tapered, just like the injector cups. When I modified the rail I had to make a new cup and weld it on. Doing so, the new cup is not tapered and I am assuming that the o-ring is not sealing properly due to this.What I am thinking now is to cut off the FPR bracket and cup from the rail, weld on a nipple, then its just running a fuel hose to an aftermarket FPR. I didn't want to go this route before since I hate the look of those stupid adjustable FPR's with the gauge on it and junk. I then thought, maybe it won't be so bad. I can have the gauge on the FPR to dial in the pressure (3.5bar or roughly 50psi), unscrew the gauge from the FPR and screw in a plug. This way it wont look as stupid. Seems like the easiest route to take and less chance of leaking. Quote Link to comment Share on other sites More sharing options...
jc43089 Posted July 26, 2014 Report Share Posted July 26, 2014 You can mount it in an inconspicuous place at least, it's not like you have to access the fpr that often. Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted July 30, 2014 Author Report Share Posted July 30, 2014 Finally after what feels like a bajillion times trying to get this fuel rail to stop leaking its actually stopped leaking. The metal that these rails are made out of just do not weld well. So I ended up cutting off fpr bracket and cup, drilling/tapping a large nut and welding that to the rail. Then I covered the entire area with 2 layers of jb weld and 2 coats of KBS rust seal paint.LeakingFixedWhile all that was happening, I kept my sanity by doing other things such as...Painting some emblems to matchAnd replacing US seatbelt/o2 sensor light with a blank pieceNow to mount the fpr, run longer hoses, put things back together and start tuning megasquirt!

Bassboy3313 Posted August 1, 2014 Author Report Share Posted August 1, 2014 After work I started on getting things back together. I put some fuel sealant on the fuel rail fitting. That needs 24 hours to dry before allowing fuel through it, so I starting on the fpr mounts.I took the left over aluminum stock from the oil catch can mount I made, cut and bent it to shape, drilled some holes and done! Sprayed it all black and waiting for it to dry. Tomorrow I will run new hoses and put more back together. DrLeadFoot 1 Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted August 2, 2014 Author Report Share Posted August 2, 2014 Well got it all together and she fired right up! Idles super rich to the point of almost dying without having an IAC hooked up tho. Hhmmm mkoepp 1 Quote Link to comment Share on other sites More sharing options...

Bassboy3313 Posted August 17, 2014 Author Report Share Posted August 17, 2014 After some setbacks Brian (Snap) and I got the car idling better with the megasquirt tune last week. Wasn't able to work on it all week, so today I fixed some minor leaks with sealant and am letting those dry over night. Tomorrow will hopefully be the day I take it for a test run when I get back from Woodstock, IL motorcycle swap meet. Let VEAL on tunerstudio do its thing and see what happens.

Earl Posted August 17, 2014 Report Share Posted August 17, 2014 I was talking to Snap the other day and he said you possibly have a bent valve. Is this true? Quote Link to comment Share on other sites More sharing options...
Bassboy3313 Posted August 17, 2014 Author Report Share Posted August 17, 2014 I did a compression test today and compression on all cylinders checked out fine. Looks like all is good. My spark plug gap was really high tho, so I regapped them lower and seems to idle a lot smoother as well. Quote Link to comment Share on other sites More sharing options...
B C Posted August 17, 2014 Report Share Posted August 17, 2014 He did the compression check and all is well, so the wadded up paper towel becoming jammed in a closing valve has been dismissed as a theory. What he DIDNT mention is that he had his plugs gapped such that you could fly the friggin space shuttle through them Quote Link to comment Share on other sites More sharing options...
