Not getting Fuel (methinks)
I fixed the water in my oil problem... went to start the new motor... and nothing.
Neptune seems to be functioning correctly.. but I think I have some wiring issues or something..
The datalogger shows 44psi (3.84v) on the map... and the tps shows -1% and wont move..
i triple checked the wiring diagrams and think they are right.. but who knows..
the car turns over great, has good spark... I have ~38psi of fuel pressure...
the car has 1000cc injectors, i setup the map to go from the stock ones to it, but havent touched the fuel numbers after that...
should I be able to smell gas on the plugs or anything? cause I cant...
can you wire a resister box in backwards
maybe I did that... i dunno.. once again i need some help here..

Oh, and I cant find the plug for ECT... I think I cut it off thinking it was power steering switch... since they are both green and black apparantly.... could that be why it wouldnt start?

Re: Not getting Fuel (methinks)
tried it... no go 
I have a second map sensor plug, that looks like its for a firewall mounted map... maybe its the one that I need to use... i'll try it...
I have no ------- clue on the tps though
or ect...
Lesson #43: dont buy a car that has been modified by other people.. it took me 6 mo to figure out my eg coupe had an integra harness... none of the wiring diagrams were working for me...

Re: Not getting Fuel (methinks)
if you're getting fucked up values for map, tps etc. I'd grab the pinout for ecu (who cares what wire color gets it there through what engine harness, go straight to ecu) and a multimeter and start checking continuity from sensor to ecu. then check the supply and output voltages and ground at each problem sensor also.
If your map is reading 44psi something is not right. But that could be a simple miswired map and a boost cut set to kill fuel. Fix your ---- before trying to figure out why it doesn't run.
