Truck will not run when you let off the brake

[itsuptwou]

Well just like the title said. I was at work a couple weeks ago and we needed to move our cars. I went to start the truck and all i heard was a clicking noise. It went away and started up. To be safe i drove home and picked up my car.
Next day tried to start the truck, same clicking noise but this wouldnt allow the truck to start if it was clicking.
Heard the noise coming from the fuse panel and it was the Injector driver module relay. Go to the store buy a new one.. same problem with clicking but i can start the truck and then dies after 15 seconds.
Now if I apply my foot to the brake the truck will start up and run with no problem. The minute i let my foot off the brake the truck shuts down and the relay will start clicking again. Im sorta at a lose right now. My lease is due in like two weeks and I have a truck that wont run. Does anyone have any ideas.
I pulled my tune off the truck as well for safety and to eliminate one problem. Im not sure if its the Computer thats going nuts or the Fuse panel is toast. Chime in if anyone knows something

Have you tried scanning for codes? How does the truck run when it does start? Is your "Wait To Start" light on when you crank or do you have an SES?

Theres a switch on the back side of the brake. Its what lets you take it in and out of gear. Im pretty sure that when that switch goes bad it won't let the truck run without pressing the brake. Its a safety deal. Im not 100% positive on this but I think I read the same thing on here not to long ago

ill have to take a look. the truck would run fine once i apply the brake. but i was having the relay problem clicking alot. will that happen if my batteries are going bad? seems if i let the truck run or drive it after a couple days it will be tough to start or ill have to jump it. no SES lights or anything though

I would start by fully charging the batteries, if they are over 4 years old just replace them.

Well bought some New Batteries for the truck just to be safe. I assume I found that switch your talking about its connected to the Pedal and there is a coder pin holding it together. If i put pressure on that connector the truck will stay running but the minute it moves around it will shut the truck down. Just have to find where to find out and how to get that one off. Im wondering if its the connector as well as the switch. This electric stuff sucks. I just need the truck to run.

the truck needs a new motor you should just trade me for my 94 idi straigth up and i will put a cummins in it and all will be good jk bro it sounds to me like it is probably just the switch i will look at one of my work trucks tommorow and see if i can see how to get it off and mayben i can help you out

Thanks, yeah its a pain to say the least. least im narrowing down the cause of all of this. Its very stressful not being able to drive the truck. Now I did notice the connector the clip was all broken off as well. I wonder if your able to just order a new connector and have to splice it into the harness or how that works. Im going over to the ford dealer i use to work at and see what they and pull up for me as well.

well i pulled my fuse panel off to check to see if there was any water spots or corrosion by the fuse box. Nothing I can notice when pulling the box out of the truck. Not sure if i need to totally take it apart to check though. If thats all well im pinning it on the brake switch and harness going to that switch. Id rather replace that at 50 bucks for both then 250 for a panel

Its 90% of the time the simpliest part. I would replace the switch and harness. If that doesn't work than you know your old one was good so switch it back out and take it back to the store. Thats what I always do
