89 bronco II wont start

[lil_Blue_Ford]

Well let me just run down the street and pick that up...

Don't think they are wired the same...

I have a computer from an '86 auto trans 4x4 BII in my '89 manual trans BII that was a 2wd.

Hey Wagner... wanna kill a beer or 6 while the F150 tries to boost her?

I think that is called "The Frankenstein Effect"

That's the boat we are in right now without all the swapping. Everything seems to be working just fine... and yet no joy.

lol, didn't think of that one...

I swapped motors only because every time I put a good set of heads on the 2.9 that was in the truck, it would crack one or both in short order. The bottom of the motor seemed quite sound, but I had used up all of my spare heads and even bought a pair of used heads. Then I picked up a 2.9 out of a BII that had gotten into an argument with a pine tree and lost. Had to swap out a cracked exhaust manifold and the water pump, but other than that it was in great shape so I figured I'd just drop the whole thing in.

Part of me wishes I would have just loaded that motor on my Ranger and brought it home. At the time I had the BII sitting in a junkyard where I was friends with the owner and naturally there were quite a few OHV 4.0L motors handy... I could have just done the swap....

Will a TFI module from an 88 work on an 89? I'm thinking yes...

Fuel pressure is solid.

It does have the usual waterfall, I mean leak, around the drip rails. There doesn't seem to be any corrosion in the area but we did get a good rain right before things started going south.

My money is still on coil/TFI.

I've seen them give off yellow/orange spark and have a no start. The problem is that when it's cold that weak spark isn't enough to get the fuel to light off.

Roughly 90% of the no-starts I've seen on the TFI systems were TFI module related. The others were mostly fuel related, bad pump, bad relay, etc. I've only seen 1 bad ECM, and I cooked it myself by mistake. They can go bad if you get a water leak in that area though.

Those trees seem to win every time.

Well if an 86 worked then an 88 should work too...

there is a water leak in that area.....but i was hoping for cheap fix lol.
BroncDan, are you feeling up to walking to home while they sit?

My choptop is not very waterproof right now... and I haven't really had a problem. Of course, I also don't have any trim around the ECU.

lol, yea, most of the time they do win.

And I don't see why an 88 wouldn't work in an 89... unless the 88 is a manual trans computer and the 89 is an auto trans. An auto trans computer will work in a manual but not the other way around (and if you put an auto trans computer in a manual trans truck, the computer usually spits out a code because it can't find the trans, lol, but other than it's complaint that your trans is missing, it works fine.)

If its a water leak in that area on an 88, it might be leaking behind the dash... a common problem with 83-88 Rangers and Bronco IIs because they had slotted cowls which allowed leaves an crap to collect and cause rust issues.

Not going home tonight... too much to do in the morning..

 

[awagner]

the leak is from the poorly sealed windshield. it just happens to pool up near the computer. but it is normaly 9 inches or so away from it unless i spill a beer there and then the old lady has a cow

 

[awagner]

dont be scared its ok you done it b4

Will a TFI module from an 88 work on an 89? I'm thinking yes...

Yeah. A 6-cyl TFI is a 6-cyl TFI. I ran my truck for 4 years off a TFI from a 91 3.0 Taurus.

 

[BroncoDan]

They are both autos...

Hey Wagner! Guess what we are doing Sunday???

Hey Wagner! Guess what we are doing Sunday???

going to Angelton and pulling parts?????????

 

[BroncoDan]

going to Angelton and pulling parts?????????

It's like you have ESP... Actually all the parts are pulled... so we are just really going to be picking up parts...

 

[awagner]

It's like you have ESP...

do you have it too...... what should you do for 1 hour after work(researching for me) at "home"
