Stupid ? , putting a 2.3 turbo motor in my 73 pinto , got it running but its running really rich , someone told me I have the fuel lines hooked up backwards , so the ? Is witch is the feed & witch is the return , stock turbo coupe fuel rail
No such thing as a stupid question knowledge is power and theres only one way to get knowledge!
Feed should be the line on the side that doesn't have the regulator. Because the regulator hold pressure in the rail and when it hits the max psi it opens and lets the extra escape into the return line.
That's the way I have it , thanks for the info , still scathing my head on way its running so rich
do you have anyway to check FP? is the motor stock? maybe the regulator is bad.
Motors 30 over ,stock steel head with ranger roller , checked FP its 38 lbs , new kerbin regulator the motor & head is new rebuild
Some miscellaneous things that may cause a rich condition:
Was the fuel pressure adjusted with the manifold reference line disconnected?
Are the components (injectors, Vam, computer) compatible? Large injectors with a early computer may cause a rich condition.
Pull plugs to see all are uniform color. If one is sooty, there may be a stuck injector.
If it is a Ford computer, pulling the codes may give some clues.
Good luck.
do you have the ground for the o2 sensor hooked up... if you used the harness from the donor its a orange wire that grounds to the compressor housing on the turbo....... if its not there you need to wire it in.... it goes from pin 49 at the ecu to the compressor housing...
#49 is hooked up , all plugs are really sooty , it seems the injectors pulse 2 times per 1 spark ,,
What year computer and components are you using? What trouble codes came up? A bad sensor could cause a open loop rich condition also, i.e. ECT or TPS. If you live in the great white north and take only short trips (engine not warming up), the engine may be running in its open loop warm up mode which would be normally rich.
The two injections per spark may be okay. Since the injectors are batch pulsed, it seems a fuel pulse every revolution would make sense. I believe the 2.3 SEFI didn't come about until the mid-90's (early 90's for Calif.), but these computers were not set up for boost.
I think computer & van are 88 turbo coupe LB2 , harness is 89 2.3 mustang with the pins changed , ( I think correctly ) codes , TPS to low , 63-66-81-82-83-84-85-86-88 , I replaced the tps & that code went away but didn't help , back fires like crazy also ,
From reading, the LB2 is the computer for a 87 with auto transmission. The 88 computer with auto was a LB3, but Ford has mixed parts at year changes. Your trouble codes 66 through 88 are not shown on the list that I have been using: http://www.turbotbird.com/techinfo/eec.htm (http://www.turbotbird.com/techinfo/eec.htm) . All the codes that I have gotten from my LA2 (87 manual tranny) were on this list, so I do not know what to say here. The only suggestion is to verify the wiring, grounds, and that the sensors are functional.
For wiring, suggest you get a Ford T-bird "Electrical Vacuum Trouble-shooting Manual" for the year computer you are using (87 & 88 are close enough to be interchangeable). Ebay has these frequently. Also verify grounds as these systems are touchy about them. Here are a couple links that may help also:

Good luck with the project.
I pulled the harness out to double check my work & found I had 2 wires backwards going to the vam ,, I got called in to work so it will be Saturday before I get to check if that's fixes it ,
