Read this post first!!! Edited/updated.
Reviving my old thread, here is the problem: Car started before (after rebuild), TPS was bad, replaced and adjusted that. Tested CPS, that was shot, so I replaced that with a known good unit, now it still doesn't start.
I read that if the tach needle jumps, the CPS [signal] is okay, but if it doesn't it's the CPS. Well, I just put a new one in there, adjusted to base timing just to get it running and the needle won't move. Now is it the ECU that's bad, not getting/sending a signal to the CPS? Doesn't throw codes when jumpered either, but it also doesn't blink quick as it should.
This is getting rediculous, I just want to drive my car, it's been about 8 1/2 months now.

I'm at my wits end. My car is an 87, just swapped a "JDM" motor in over the past 8 months. Car started up and idled perfect two weeks ago, but when I would hit the gas it would bog down. I was talking with Bondango and was told it was the TPS, even though it was not throwing a code. After changing TPSes with another that I had and changing the ISCV, it quit starting and hasn't started since. So after waiting for like 2+ weeks for a slow seller, I finally received another TPS today and put it on, adjusted to spec, and car still does not start! (Put good ISCV on too) When it was running I had adjusted timing, it was spot on. Usually after cranking for a while you can smell fuel, but tonight I couldn't smell any at all. I tried jumpering fp and b+ but didn't hear any fuel flowing...isn't it supposed to turn on the fuel pump? All through the night I had been checking codes and not one had been thrown, but it didn't blink fast like it should either. I sort of thought it may be the ECU because one day it threw code 51, and never did again. Another day (when it was running) it threw the knock sensor code but never again, and another day it threw the "no signal from tach" code, but not once again. Now nothing happens and I'm stumped. HELP :1zhelp:
Cliff notes:
Car started and idled fine two weeks ago, hit gas and bogged
Changed TPS/ISCV wouldn't start, hasn't since
Put new (and adjusted) TPS and ISCV on tonight, still won't start
FP and B+ jumpered=couldn't hear fuel flowing/can't smell fuel while cranking
Thrown misc codes over different days only once, never repeated though
