Please Help check engine light 1994

Having issues with my 1994 Bronco. The other day at a light the check engine light came on. When I went to accelerate the car from a stopped position, it wouldn't go. Then I pushed the accelerator all the way down and it crept along making a large clunking sound and had a strong odor or fumes. It made it to a parking lot about 1/4 mile down the road where it then just completely died. I turned the key to turn the car all the way off then back on. It started up without the light on this time and drove fine. Also there is a lot of fluid coming from the engine area into the garage floor. A puddle large enough to spill down the garage floor into the driveway. Fixed this issue it was a blown radiator hose. Went out for a drive and the same thing happened again but this time know issue with the radiator hose we found a pinched shorted out wire for the high beams, so we repaired. Took it out for another drive had the same issue again. Any suggestions I am out of ideas.

Battery and alternator check out fine
Temperature gauge does jump around when stopped
Doesn't seem to be running hot
It happens after driving about 10 miles
Trans fluid does leak at seal but there is plenty of oil in it
It's only driven a few times a month but prior to this it hadn't been driven in over a month
Transmission was rebuilt about 6000 miles ago
130k miles on the engine

Marlin, to help diagnose a check engine light you need to read the codes .Code reader is handy but advance auto and other auto parts stores can help out with that. Good luck!! TR

Thank you

I just order one that is wifi with iOS. I have the bronco at my mechanic who serves our cars and they have been struggle to id the issue. They thought it was fixed twice and as soon as we went to drive it same problem occurred. I am thinking today's mechanic don't really know how to work on older cars so I'm trying to help where I can. I am looking in the Austin area for a garage who works on older cars. But any help in the mean time would be great. Thanks.

I had a similar problem with a Bronco II I had several years ago and finally found the ground for the LP fuel pump in the tank was bad. I had replaced distributer once, coils twice, Ignition modules twice, plugs once, fuel pressure regulator, injectors. I test fuel pressure when it was cool and it'd be fine but never checked it hot. I had problems with the fuel sender and went to fix it, the ground wire had come off. Replaced the sending unit and pump and ensured I had a positive ground and the problem went away.

You don't need a scanner to pull the codes, just jumper the connector and count the flashes of the check engine light...


Here's a more detailed "how-to"...

With the code, you can follow the pinpoint diagnostics in the factory manual to diagnose the problem. I would think that your shop would have done that.

Anyways, post the code(s) when you get them.

I have never seen one of those for OBD-I vehicles like your 1994 Bronco.

I used to use that trick a lot when I did truck servicing at U-Haul. They were to cheap in our market to buy code readers till the OBD II became the standard on newer trucks then they had to.
