I pulled in to the drive-thru at the bank and it just shut-off and I would not restart. People sitting behind me beeping there horns and cursing, I didn't even give them the privilage of saying something back to them. An older gentlemen who was walking down the street was the only one whom offered to help and helped push it out of the way and try to figure out what happened.
I tried to read the codes but I kept getting an error message. I checked all electrical connections and finally checked my fuses, it seems like either the ignition or the pcm fuse came loose and it fired right back up after about and hour of scratching our heads and having my wife bring the jumper to me. I did alot of wiring up lights this weekend so I'm thinking i just didn't push a fuse back all the way in and it came loose driving around this morning. Would either of these fuses cause an error to display on the code reader? I hope it's not something else. Ran like a champ afterwards.

 

if the fuse for the PCM comes lose, you will get the error message because the PCM isn't getting any power.....even when the truck is off, the PCM gets power.....without the power source, the PCM couldn't be activated...

 

That's whatt i thought because I wasn't getting any spark, just cranking over and over. Thanks for the quick answer. I'll give you a deal on that cooler.

 

Thats happened to me before, luckily i was in my driveway. I shut it off after i got home from class & it would'nt really start....I would start it, it revved to 1,000 RPM then immediately die. After messing with it for hours it finally stayed running, i still have no idea what it was, im glad it hasnt happened since.

 

mine has done that before. just turning over but nothing. under the dash just to the right of the glove box theres a button try pushing that. i think its a fuel reset or something but it worked.

 

So far it's working great. So I'm keeping my fingers crossed.

 

Wouldn't start again this morning. Once at the house and once after I dropped the kids off at the mother's house. I had to play around with the fuses again. It rained really bad last night so there may have been some moisture in there. Any one have any suggestions on keeping the moisture out or making the fuses stay put. I usually leave my window open a half an inch since I have the rain guards around the windows, wondering if that has anything to do with it.

 

Do the fuses feel very easy to slide in? Maybe they are a bit loose.

Some di-electric grease on the contacts may help?

Something else...

One of my Lightning bros. had a similar issue. After giving up and towing it to the dealership he found out that tapping a wire / power lead off of a fuse connector can cause the terminal to push out the back side of the fuse block.

Know what I mean? He was sticking a wire into the slot where you push a fuse into.. then pushing the fuse in on top of it. (we've all done it)

He had to wind up replacing the whole fuse block.

Rich

 

^^that will cause it...

 

That is quite the possibility. I will have to check this out. I use them little fuse taps but this is still a great lead. Thanks!
How much do fuse blocks run and are to easy to install?

 

I donno.. pretty sure the dealership would have to order one.

Just something to look for when trying to diagnos.

Last night I checked out my fuse panel and everything seemed ok. Took out all the fuses and made sure they were all in nice and tight except for my dome light fuse, fixed that andplace some electrical grease on them.
Went to drive it and I had to drive with 2 feet feathering the gas for like 10 min before I was able to drive with one foot. It started up and ran great today. Wondering if it was just the pcm relearning or if there is something else wrong?
I added a heat shield to my K&N filter but I doubt that would cause any problems. Did not mess with the MAF or anything just cleaned it with MAF cleaner. All connectins are tight.

 

The computer does learn but it would'nt do that.

Next time it does this try disconnecting the maf. It'll throw a light but it just might run better. If so you know the MAF needs to be replaced.

Could also be a map sensor. I had one of those go out on a sable once. Would'nt hardly run until the motor was warm. Never threw a CEL either.

Rich

 

Thanks I'll check them 2 items things out. Map sensor is located on passenger side near the firewall next to the washer resevoir, right? It does not throw a code when this happens.

 

Not exactly off topic but food for thought:
I just got done figuring out why my 93 Dodge would turn over but not start every time.
Some days no problem,others just no go.
I'm picking up a new ignition switch Friday as I found one of the wipers inside has worn down to nothing.

 

If it were a ignition switch.. you could bang on the dash (in the shin area) and see if it ran any different. WHo knows? Hope you figure it out.

Friggin again it died. I played with the one fuse, I believe it is one of the PCM fuses and the check engine light would go off and on as I wiggled it. For a second I got code 1504 from the code reader then it couldn't read anything. Finally I held the fuse until the engine light stayed on and it started up. I can't find that fault code anywhere.

What the H*ll does that mean? Could this cause it to stall like it's been doing

 

First it wouldn't start this morning. Got it started by messing with the fuses. Then it died a few blocks away. Again got it started by messing with the fuses. I think I have this narrowed down to the fuse block since I held the pcm fuse until my cel stayed on and it fired right back up and ran fine the rest of the morning. Still confused about the 1504 code. I think that might have just been a fault when it stalled since it cleared itself. I might as well buy a new IAC to make sure.

 

I went to the salvage yard this morning and found a Ranger of my year and got the fuse block. I have some wiring to do tonight. But I also picked up a IAC valve, Ford OEM. A few other sensors i may someday need all from a Ranger that was just put there. I also struck it rich with a MAF from a 4.0 explorer with the hood closed and still with the original air filter box. I pulled the MAF out and it looked brand new, I'm hoping it is the same part number as the Ranger. Wish me luck!

 

Well instead of replacing the block I just squeezed all the little connectors inside the block together and it worked like a charm. No more dieing on me. Thanks for all your suggestions.

 

So it sounds like the problem is in the fuse block right? At least you know what it is. I hate electrical problems.. drives me nuts!

Rich

 

Yep, Fuse block was the problem. I hear ya with the electrical problem, they suck.
I still have a 1445 code I haven't found the cause of yet since it's electrical.
