92 300 5 Speed - Died/No Start - Input needed please!
Hi everyone, I'm fairly new to FTE and have posted mainly over in the Bullnose forums. However my 92 Beater truck and I need some assistance.
My thread over there: https://www.ford-trucks.com/forums/1...tractions.html
Friday I fueled up the 92 for a 3.5 hour drive. It started/ran fine, but within 50' of the gas pump I BRIEFLY smelled something vaguely electrical (not certain where, it was very short, but if I had to guess I'd say the dash/interior) and then it suddenly wasn't running.
I replaced the fuel filter a couple days ago and I've put 800ish miles on it without any engine related problems. Right now it will crank, the fuel pump goes through it's priming cycle, but I don't think it's getting fire.
I had to be gone all weekend and haven't had a chance to fiddle with it, the only place I can think to start is with a spark test. After it stopped running I did pull damn near every fuse in the inside and underhood fuse panel and couldn't find any melted ones. But I'll check again.
I did notice when I bought it that there are three wires in a harness leading to the top of the coil (not counting the dizzy wire). Only the outer two wires are plugged in and the middle is hanging loose. I have no idea what that is about, but it ran great, so I let it be (ain't broke...). The CEL flickers on/off all the time. I figured it was due to the deleted CAT or some other pointless issue.
The breakdown forced me to tow it home with my 83 Ford and then go borrow my buddy's 94 Fullsize Blazer... a bit embarrassing
Is this the symptom of a common issue and where do you guys suggest I start looking? Thanks in advance for the advice.

But it's not even British, ha. Thanks, it happens.
I'll be calling the yards around here tomorrow. Figure $45-$100. It's $245 from Advance, $235 from O'Reilly, the only used one on ebay is $260.... this was the cheapest used unit I've found online as of yet.

I'm wondering if the EEC from a '93 I6 truck with an E40D would work, because I have been offered the entire truck for $450...
I did find this thread.

Follow-up
I found the info below in regard to EEC interchanges. The interchange info was confirmed by the O'Reilly's website that stated the ARB computer would work with 92 f150 with a Straight 6 and a manual. Turns out the ARB computer runs $103 from Advance as opposed to $245 for the APB computer. The distributor accidentely sent me a computer for a truck with a E4OD and a straight 6. Due to the holiday and shipping it took forever to exchange, so I figured I might as well try the auto computer. It works... but the truck would idle WAY high for a few seconds after start up due to the lack of input from the trans and took a little longer to come down to idle at stoplights. I traded it for the correct ARB (manual trans) computer today and it starts and runs perfect.
Now... to read the codes and find out why the CEL is on.

You'll have to hit the phone book for your local salvage yards.
You'll need to find a match to your existing computer by the numbers.
You should find a number something like "F2TF-12A650-APB" on your ECM. The F2TF means F2=1992, T=Truck, F=Engine management(more or less). 12A650 is just Fordspeak for engine computer and is found on almost all Ford computers. The "APB" or whatever the last 2 or 3 letters are are what counts. The ECM you need can be from a 1992 or 1993.
If you have a California truck, you need an AUA or AUB
For non-California trucks:
APA, APB, and ARB-all interchange.
ASA and ASB interchange.
ATA, ATB, and AEA interchange (sometimes found in E150 vans too)
NA, NB, and NC interchange.
TA is by itself but found on 93-95 trucks.
XA is also by itself and also found on 93-5 trucks.
Note that the interchange does not explain WHY for example XA cannot be used in place of an ATA(or whatever). Such a swap might possibly work if you get desparate, but you're on your own trying it.
Note also you might even have a code not listed. Ford used a buttload of variations and it's not unusual to find a number which "doesn't exist", especially if the computer was replaced by a dealer at some point. In that case you will either seek help from the Ford dealer or take your best guess from the list above.
Good luck. Be aware that although a junkyard will happily sell you an ECM, the won't gaurantee it to be your problem and likely won't give your money back if it fails to fix your truck. Most mechanics consider a computer swap the last resort as the boxes give very little trouble versus the large number of underhood components that do commonly fail. Salvage yards know this and will likely tell you, "you buy it it's yours". Should the box be bad they will exchange it but likely not give a refund.

That's great info on the computer - I've got a 1996 4.9 5 speed that I think takes too long to idle down at an intersection. The engine won't idle down from about 1500 RPM until I've come to a complete stop. I wouldn't be surprised if this truck had the wrong computer in it. I've had tons of fun fixing what the PO considered appropriate fixes. 
In any case, I'm glad you've figured your problem out! (Sorry to do a little hi-jacking.)

I am currently using a 92 4.9L E4OD ECU in my 89 F250 with the AOD tranny. It runs OK but I know its not happy with the E4OD missing! I too have the higher idle at start up, I hit the gas pedal and it drops down. I don't have any other issues so far as today was the 1st day driving my truck after the engine swap.
