89 bronco II wont start

[BroncoDan]

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?

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...

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.)

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"

[awagner]

i take that as a "nope""should'nt""but hellz yeah" and we will hash out all we learned today on this beast

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.

Actually I believe the TFI off of a V-8 is also the same part number. If I remember correctly, only the fullsize trucks with the TFI on the inner fender have a different part number.

 

[awagner]

ok changed the tfi and map sensor and still no go. anything else i can change?

 

[awagner]

another thing, we have spark but it is weak. If the timing chain was broke would you still get spark at the plugs? Compression is 115 at 5 cylinders and 110 on one.

 

[adsm08]

No timing chain = no spark.

The chain runs the cam, the cam runs the dizzy, the vane wheel on the dizzy makes the signal for the spark.

Have you replaced your coil yet?

yes put in new coil also

 

[adsm08]

hmm, new TFI, new coil, poor spark....

This is got me over a barrel. Kinda wish I could come look at it myself, it'd be easier to figure out.

i wish i was in a barrel....this has been a not so fun last few days, no idea what else to try. the only thing i havent replaced is the tps. whould that cause her not to fire?

 

[adsm08]

doubtful, but I suppose it isn't impossible. I've seen dumber things.

Matter of fact, I've seen a shorted TPS cause a no-start on a Crown Vic Interceptor, right off the truck.

how did it act? did it still crank? is there any way to bypass it to try?
