Well guys I have installed the 87 5.0 into my 88tbird. I have the 88 5.0 harness and computer installed correctly, and all vacuum lines connected as they should be(i think). I'm getting spark, fuel pressure, and power to the starter. The engine turns over and starts but dies right away. The gas seems to be okay.
Anyone have any ideas what to check?
I'd run codes, based on what you say I might suspect the TFI module or it's wiring. It sounds like when the TFI switches from start mode to CCD (run) mode is where things are going wrong. Sometimes pulling the spout connector confirms this.
alright I had an extra one, so I swapped them and have the same problem. I'm wondering maybe if my distributor was repalced and put in backwards, so all the plug wires would be backwards too. I know my 3.8 was like that. I'll have to check that too. I was thinking the computer might be junk too, but I don't know.
Anyone else have any other suggestions?

first off, this should be in either engine tech or engine swapping. Whats your fuel pressure? what did you use for lines to convert it? did you swap out the fuel pump? is your fuel pump relay coming on? do you have voltage at your relay? what wiring harness did you use? What about codes?
Without any help from yourself we can't help you.
oh, and whats your timing set at? I would have checked the firing order first...
I used the SEFI High pressure hose to connect the lines. I'm not sure of a number for fuel pressure, but I am getting it. I can't hear the relay but its got to be working, if i crank over the car and it "starts" if I hit the fuel bleed nosle it does come out. Where is the relay to check the voltage at? I used a 88 cougar v8 harness and computer. Its an 87 tbird 5.0. I haven't gotten a check engine light, no way to check for codes. The only access i have to a code reader is at my brother work, but the car doesn't run.
The fuel pump is the one from my parts car. That was swapped in a while ago. The timing is set at what is was when I pulled the motor, it ran and drove to my house when I bought it. Anyone have a firing order and distributor order diagram?
Bump.
I think i may have found the problem. On the injector harness which is connects to the main harness, the bottom of the white 10 pin connectors, is an orange wire. Its broken, but doesn't appear to tie into the mass of wires. It appears to be a ground for the injector harness. Is there a ground for the injector harness? This could explain why the car starts then dies. Can anyone confirm this is indeed a ground wire? Where is it normally grounded? I couldn't see the other part of it on the back of the block or firewall. In my manuals the ground in question is G602. There are two wires which connect here. One is the drivers side o2 sensor, can anyone tell me what the other ground here is?
On my v6 engine, the one that came out of this car, I can see an orange wire which connects to the back of the motor. This is why I kinda assume its the same wire it just goes to a slightly different place.
Any input?
post some pics of said wires... they always help
Aaaaaahhhhhhh, the old ten pin connector...... most likely not your problem man, that orange wire.... a lot of people had that same wire disconnected too i know i sure did. Here this should help (http://www.foxtbirdcougarforums.com/showthread.php?t=21560)
also, when you say the car "starts", clarify that just a little...... does it actually run for a few seconds, or just start to fire while you're turning the key, but then when you let go of the key it dies..... that's the problem i had when i did the ho swap
Yes! Thats what it does when I let go of the key it stops. What was the problem in your case? Please tell me? :)
hmmmmm the suspense :)
i was afraid you might ask this :)
anyway, i did a hack job on my wiring because i got the ho from a 91 t-bird and didn't have the funds for a full 87/88 harness, so i used the 91 wiring harness wasn't plug and play with the 83.......
i don't know where the wire might be on your car, but i had to get a 4 pr0nged starter solenoid (2 big studs for the wires and 2 small ones)..... and add the blue wire that you see in the picture on the small solenoid pin next to the strut tower...... in your case, your solenoid may just be hooked up wrong....... anyway, i was told that the wire i had hooked up on the other side was losing voltage when let go of the key and was causing the engine to stall..... the blue wire i added is from a ignition switched source that allows the solenoid power not to be broken when switched back from start to run
i hope that makes since, it's been a bit since i had to think about it :)
i'd check your starter solenoid and how it's wired :)
p.s. when you look at the pic, there is also a blue wire added to the battery post, that's for the hood light, the solenoid one is a different wire :)
i just peeked again and it's hooked to a big yellow wire from the other fender wiring harness.... i'll try to track it down to tell you exactly what it is....
Thank you. I did take the starter seloniod off of the v8 car but maybe something is backwards. Thanks for the quick responce!
wait, what is hooked up to the big yellow wire? Connected to which fender the passenger side?
no, no, that was on my car..... disregard that.... i had an eec-iii harness and grafted an eec-iv harness to it :) you don't have that wire....
i just went outside and did a little diag (you can do that in fla at a quarter to midnight barfooted and in shorts :hick: ), and i found that that wire was indeed a switched 12v source.... when i turned the key to the on position it lit, while holding in start it stayed lit, and when i let go of the key it kept pumping out voltage :)
Alright. Im a little confused as to what should be connected where. Im sitting here looking at the manuals but im not seeing a starter selonoid with all the wires attached. Any idea what wire is on the wrong side?
is your solenoid a diamond looking 4 pr0nged, or the cylinder looking one?
looking over my car, my wiring may not help..... my starter is the small version and has a power lead directly from the battery and another power lead from the bottom of the starter solenoid.... if your is like that, all my power wires are on the top big post, the only wire on the bottom big post goes to my starter, the wire on the left small post goes to my main engine wiring harness, so i'm not sure where it goes, and the wire i added on the right small post goes to the 12v switched power source that retains power through the start cycle
hope that helps
one of these days i'm going to get a full harness and get rid of that rats nest :)
p.s. my 91 evtm (for the engine) isn't much help for the starter solenoid wiring either, only my 83 evtm shows it even exhists... yeah ford :)
Well there was 2 wires on the side with the starter, one had a bunch of fuseable links, so i swapped it over to the other side, and.... she fired right up, and kept running. Thanks a lot man for the help, I really appreciate it. I was really hoping I could hear the bird run this weekend, thanks. Its been a year long project and now its over( i mean it still needs to be cleaned up and tuned up and so forth), but all the hard stuff if done. Thanks Again, I owe you one!
cool :) glad it was easy:burnout:
only beecause you happened to be up around midnight and signed onto the forum, otherwise it'd probably still be banging my head against the wall. I was begining to think the ecm might be bad, but nope, just a wire only getting juice when the key was turned lol. :)
You the man!
