Used to run good... Part 2

[regarrr]

So I got some things accomplished. Unfortunately nothing took care of my problem. I'm not getting any spark and it really looks like I'm not getting any fuel either. I took my ignition control module (mounted on the carburator) up to Advance auto parts and had it tested. They said it was bad so I went ahead and bought a new one and put that on. Same deal, cranks but won't fire up. I also checked for compression at the number 1 spark plug. I got 6bar. I'm not sure what the actual pressure should be but 6 bar seemed pretty good. I'm at a loss. I have no idea what else to do.

regarr,

I and I am sure others would really like to help you, but we will need a two way communication of information and suggestions. You will have to give as much information as possible regarding what you have done, what you have tested and how, what the results were, and any other observations that you make. When someone makes a suggestion, you will have to consider it, and either try it, and let us know what the results were, or if you decide not to try it, let us know, with your reasoning.

Your statement "So I got some things accomplished. Unfortunately nothing took care of my problem." Tells me nothing of value. All I know is that you put your knee, or foot, into a rat's nest of wiring, and now your truck won't start.

So... what have you tried, and what have you discovered. Also how have you determined that you are not getting spark, and what makes you think that you are not getting fuel?

And the icm mounted on the carb in a fuel injected vehicle? I also agree you need to dedicate some time and sit down for some 2 way conversation if you want to get this fixed.

The beast is alive again! I kinda feel like an idiot though. Turns out I pulled a wire out of one of the plugs thats mounted to the aft side of the air intake filter box. I used Joe's article about diagnostic codes and I got a 22, and the same time I was checking the codes I heard my fuel pump come on. While i was playing with the troubleshooting plug I inadvertently jiggled that wire that was pulled out. So it turns out that that wire was my problem all along. I'm glad I didn't find it right away though, by trouble shooting other things I actually learned a lot. One of the reasons I bought my Bronco was for a learning experience. On the other hand I neglected the golden rule to start with the most logical thing first. I feel stupid about that. Thanks for all the good advice Joe. I will try to be more clear about what I did the next time I have an issue. Thank you again.

Oh, Yardape, sorry I meant to say distributer. I don't know why I said carb. Sorry for the confusion.

regarr,

This has been a rewarding experience for both of us. I'm glad that you got your truck running, and that you learned as much as you did in such a short period of time. You also learned the importance of clear communication /emoticons/[email protected] 2x" width="20" height="20" />

If you still have code 22... MAP/BP sensor out of self test range.

You need to locate your map sensor, it is high on the passenger firewall under the hood, with a vacuum line attached. Make sure the wire connections are clean, and check to make sure the vacuum line is clear (by blowing through it) and tight. You may want to check to make sure that you have full vacuum coming to it by way of that line.

I am pretty sure that there is a way to test it, I'd have to look it up. The first place I would look would be Miesk5's pages at www.broncolinks.com or www.fordfuelinjection.com or maybe I would check my haynes manual :|

hehehe... let the learning continue /emoticons/[email protected] 2x" width="20" height="20" />

These Bronco's are great for learning on. THey are old enough to have parts wear out, have brittle vacuum lines, or corroded electrical connections. They are new enough to have computer controlled components, and sensors that give information to the computer, yet; they not quite as complicated (I guess) as the new cars. However, what one learns working on his/her Bronco can eventually be brought forward to working on his/her newer cars.

I have learned a lot working on mine, and even more by participating in discussions trying to help others troubleshoot their vehicles. Before I got involved with our Bronco, the last car I worked on still had points and a condensor under the distributor cap. I paid $100 to have this Bronco flatbedded to where my son was going to mechanics school so that he could learn how to troubleshoot it.

There are a number of people here that know far more than I do, and I learn from them on a regular basis. I hope that you continue to learn, and as you do you share your experience with others.

Hey no worries I just wanted to make sure you knew what the icm was.
