My 91 Bronco with the 351W just died going down the road the other day. I, being retarded, reset the computer so now I cant even read the codes. Im new to this working on cars stuff so you gotta cut me a break. It turns over but I just dont get spark. So far I've replaced the ignition coil, cap and rotor, plugs, plug wires, battery, and control module. Whats the next step for me? Sorry I cant be more descriptive of the problem, but thats all I know.

How did you check if you were getting a spark?

 

[AlwaysBroken]

I pulled a plug and grounded it and then tried cranking it over. Got nothing. I was talking to the guys at Autozone and they think it's the stator assembly. Does that sound right?

 

[Aikidoka]

You can hold the coil wire just over the cap so you can see if a spark jumps the gap. It will have to be close and make sure you aren't using your bare hands. Then you would know there is a problem between there and the plugs. It cranks though right? If everything in the ignition system as been replaced then I would think the computer is the only thing left. My bronco is carbs so I can't help with that. Maybe there is a way to check the voltage on the wire going to the coil from the control module.

Yes, but you need to change the TFI modual and stator togeather to make fix them. IF they are indeed broken.

 

[RLKBOB]

did you check to make sure the rotor is turning on the dist?

 

[AlwaysBroken]

Is the TFI Modual the same as the control module? If so then I just replaced that about a week ago. But I got that stator assembly in and it fired right up. Drove it down the road alittle and it died on me again. Just like before. Is the computer the final step for me? Thanks for all the relies. They've been mucho helpful.

 

[Fireguy50]

no, leave the computer alone.
Change the module and stator agian TOGEATHER, then it should be okay.

they pass faults to each other, so the old stator ruined the new module. Sucks huh :banghead :thumbup

 

[AlwaysBroken]

One last thing... Anyway to test for a broken computer? Can a broken computer give you codes to tell you that it's broken or is that wishful thinking? Thanx again

 

[Fireguy50]

Um, yes there are internal computer fault codes. But a broken computer won't always tell you.

Lack of spark while crankign is NEVER the computer. If the vehicle is working corectly, you can get a spark during crank whith no comptuer installed. So, keep looking for the problem :twak :beer :thumbup

 

[AlwaysBroken]

Alright, one last question. Since I put the new stator in and drove it for 2 seconds down the road should I replace the new stator again tomorrow with the new control module or should it be fine just replacing the control module only? Thanx, you've been alot of help!:thumbup

There ya go.

 

[AlwaysBroken]

Ok, took the control module to autozone for testing and it passed with flying colors. Maybe Ill just start replacing random parts until it works!:shrug But thanx again for all the help!

 

[Fireguy50]

Testing the comtrol module? :lolup
So you trust a child with cookies when your not looking?

Just kidding :beer
The TFI control module is famose for failing, ford lost a laysuit over it:

It likes to go bad when it's heated, or just be tempermetal.

ok, so today I bought a "new" remanufactored distributor figuring this is the last possible problem area, so by just replacing it like this Id be sure to fix it... Well you can guess it still doesnt work. Whats left that would cause me not to get a spark after replacing the plugs, wires, entire distributor, cap, rotor, control module, and ignition coil? And Im pretty sure the control module is good, they tested it 4 times in front of me.:shrug Does the inertia switch only cut off fuel or does it cut off spark too? Im completely out of ideas here.

Oh, and I tried to read the codes. I have one of those cheapie actron ones. The prev. owner gave it to me with the truck. But, everytime lately that I try to get a code the light just stays on constantly. No blinks or anything. And Im pretty sure im doing it right. I hook it up, then go turn the truck to the on position and then go wait for codes but get nothing???

 

[Fireguy50]

wiring between all those components

So what's the best way to test all the wires in that wiring diagram? Just get ahold of a multimeter and start splicing into wires and testing them? Sorry for my ignorance. This working on cars thing is tough!:banghead

 

[AlwaysBroken]

Also, if there is something wrong with the wiring harness can I just buy a complete new one from somewhere? I want to get this fixed soon because it's starting to get cold and working on the Bronc when it's snowing outside is no fun!
