Well, after a year of building this truck she finally flashed up today. Ran fairly well all things considered. Run for about 20 min at 1200 rpm to break in the new cam and I had to shut her down due to some electrical gremlins I just couldn't live with. This is my first post looking for advice on this build and i greatly appreciate any feedback.
Background on the build is long, but I will try to give only the necessary:
Smarty sr and edge stacked (can't fund efi right now)
Grid heater delete including all wiring and solenoids
Ppe dual cp3
Fass 150
Ddp 150hp injectors
Colt stage 4 cam
Balanced blueprinted and ceramic coated
Sleeved block, fire rings, 125lb valve set
Girdle, Carrillo rods, etc etc
Sxe366 sxe480 compounds
More than you needed to know but gives you an idea of what kind of power I'm after...
So upon first fire up I had no throttle pedal. Set the cruise high idle to 1200 and went about checking for leaks. Everything seemed happy. After about 10 min run time she started jumping about 50rpm randomly and sporadically, the lightning bolt on the dash and volt meter showing only maybe 12v. So ok alternator dead, no biggie. Fass was sounding real funny and motor was pretty darn hot so I checked the voltage with an ohmeter at the battery. 16v!!! Woah... ok, so she was fairly warm by now and I went to shut it down. Figured I'd try the throttle again. Works? Kinda anyway... won't let me hold an rpm just keeps rising without movement. First 1/2 inch is dead then it takes off...
So I read the codes and this is what I got;
Egr: who cares...
Cam positioning sensor: missed that one installing the wire harness... plug in and clear that code...
Gen output high: no ****
Voltage low: wtf...
Few others such as o2 sensors and egr
Lost com with vgt: yea, its on the floor
So I disconnect alternator and run it again. Battery's on the charger showing 12.5v, alternator still putting out 16... had all the same codes come back but the 50rpm jumps went away, the dead Pedal didn't.
Gonna throw my spare alternator at it in the am, but I'm seriously scratching my head with the dead pedal and lightning bolt on the dash. And at a loss as to why my alternator gauge on the dash showed hardly any voltage while the thing was spitting out 16v. I'm sure someone will say grounds but which ones?? The only ones I might have wrong are the ones tying the ecm to the engine mount on the driver side, tell me if that sounds wrong please.
Damn, long post... hope someone will suffer through reading that and have some direction to point me in
Thanks in advance folks
