Start off by saying it's been a LOOONG time since I've been here. Switched trucks quite a bit since then. Now have a 1990 Bronco XLT 5.8 with 80k original miles.

Can't get it to go into code mode. Tried the trick with grounding the code wire. Still won't do it. But here's what I know:

-Won't start without starter fluid
-Turn the key to run and the pump runs, but doesn't shut off
-There is gas
-If I push the bleeder nozzle on the fuel rail while the pump is on, fuel will dribble out but not spray hard (low pressure?)
-Can't pull any codes and not sure why (don't have a check engine light just wondered if there was something there) Won't enter the flashing mode at all.

Any other help would be awesome. Thanks!

 

The items in bold above are classic symptoms of a failed computer. Pull out the PCM (computer), open it up and inspect for signs of leaking capacitors. Another very common problem.

 

Thanks and I'll check it out. Just need to know where it's located. Drivers kick?

 

Yes sir

It comes out from inside the cab on your model year truck.

 

The guy I bought it from put a brand new battery in 2 weeks ago and hadn't driven it. Wonder if that fried something.

Anyway, was poking around and this Bronco is amazing. No rust and doesn't look like anyone has molested a thing on it. Found the build sheet under the back carpet which is original yet looks new. Think I got a good deal at $1,800?

 

One more thing!! Is the PCM the same as the EEC/ECM? I'm reading that there is also a computer behind the kick panel.

EDIT: N/M Same thing.

 

So yep, leaking capacitors in the ECU.

Do I need the exact F0TF PD model? Hoping to go to a junk yard and find one instead of forking over the $120.

 

F0TF-PD is a PCM for a 5.8L bronco w/E4OD transmission AND California emissions. If you live in Cali. you need one of those. If not you could look for a similar year PCM from a Bronco/F150 with a 5.8L/E4OD combination. Approximately 1988 to 1993.

You could send yours to this place to be repaired: http://www.ecurepairnow.com/

 

New computer installed. Fired right up. Thanks.

 

Glad to see you got it going. Thanks for the feedback.

You are welcome
