2.9 Starting Issues

[MLB]

88' Bronco II with the 2.9, when you start the truck cold it will fire up before you can turn loose of the key, but after driving for any length of time and go to start it back up it wants to crank for 5 to 10 sec. before it will start. It does'nt seem to matter if it sits for 30 min. or 3 hrs ? Any ideas ?? Thanks.

Once it cools down does it fire up? After it dies do you not have spark?

Yes to both = TFI Modules giving out.

Yes, it will start up after cool down it just takes a few more second cranin on it.

Any other ideas ? What exactly is a TFI module ?

The TFI Module is on the back of the distributor. Hes a run down:

Also, if you do not have spark when this is going on, you need a new TFI.
