 Third attempt to start

water temp sensor
As long as I was checking wires I decided to rewrap the fuel injector wiring harness and used a 1/2 to 3/8 brass pipe fitting to put the coolent temp sensor into the manifold.  This looks better then my earlier solution.

After following up on all the suggestions from the guys on the forum I concluded the computer must be bad. So I bought a new computer.

Wa-la! With the new computer the fuel pump runs and shuts down after about 2 seconds like it should. Plus I am getting KOEO codes now.  The computer was bad!

Did I mention the donor was a running donor? I figure the prior owner must have modified the wiring instead of buying a new computer.


temp gauges

The KOEO codes told me I had to adjust the Throttle Position Sensor and I had to put a resistor in the "EGR Vacuum Regulator Solenoid" connector  (because it did not go to a solenoid).  Using a 33k ohm resistor was enough to make the computer think the solenoid was there.

The engine now sputters but will not run. Oh it is getting so close. So I  temporarily installed the Mustang gauges so I could see if I was getting oil pressure.

I bought a fuel pressure tester (could not find one to borrow) and found the pressure in the supply line was a nice 40 pounds. Right within range.


running engine
I felt the headers and some exhaust ports were hot (they were firing) and some were stone cold (not firing). I pulled a spark plug and it smelled like gas.

They were new plugs and at the auto parts store they said to gap them at .054. I checked the shop manual and it said to gap the spark plugs at .050.  So I regapped the plugs and guess what.

IT STARTED!!!

It does not idle smooth yet but it is running on all 8 cylinders. It sounds awesome!.
