200 HP Chase Begins .... Now Completed 14 Months In. WooHoo !!

Try another MAP sensor
 
Today I got a compression tester from Harbor Freight. Bad choice ... don't do it. It is going back for a refund. Nice kit but doesn't have a schraeder valve in the hose and maybe a bad gauge. Reads very low. Was able to use one of the adapters with Jerry's gauge that came with a classic car he bought several years ago. His does have a schraeder valve in the hose. Anyway the numbers came out as (1, 2, 3) 200/195/195 PSI. Neville says the HF gauge system I used is deficient and doesn't give the full proper reading. My altitude at 2,500 feet. Neville says he reckons my numbers are OK considering.

Here are the spark plugs (1, 2, 3). Cylinder 1 was the only one making enough heat to make the header pipes hot.

#1 looks like it's rich/not firing correctly
 
#1 obviously is firing and has fuel... maybe a bit too much but I wouldn't worry about that yet.
#2 shows minimal carbon on the negative and center electrodes (hard to see) indicating either poor spark or not enough fuel or both. (Have you confirmed that you have spark at the plugs?)
#3 shows some carbon build up on the electrodes indicating spark taking place but minimal fuel being burnt.

None of the plugs are wet indicating over fueling or flooding.

Based on what I see, assuming you have addressed the vacuum line issues and checked for spark (curious to see if #2 and #3 primary wires to coils are crossed), I'd be checking those injectors for some form of contamination.

The compression numbers you stated shouldn't be causing a problem with the engine only firing on 1 or 2 cylinders.
 
Believe I'd try a new set of plugs, with assembling a new engine, with oil on piston rings, valve stems, guides etc., can foul plugs, and hard to fire. # 3 looks like fuel fouled/glazed, and #1 rich or oil fouled, not firing. New plugs a cheap easy way to start.
