Hey guys,
It's been awhile since I have posted on here but I need some help again.

The story: Three weeks ago I jumped in my truck for a real quick trip to the store. It was cold so it was a rough start but it did start. Without letting it warm up I put it in drive and went on my way. 2 minutes down the road it died. Quick I phone search on this website I was able to see that it was fuse 22 because it had the typical no wts light and it would crank, but not start. Disconnected the fuel heater (or so I thought), put a new fuse in, and went on my marry way. However, yesterday, same scenario. I had just got out of the driveway and the fuse blew again. WTF!! I thought I had fixed it. The common symptom in both of these instances was that my truck was really cold and I may have not let it warm up enough like I usually do. Also, I didn't have it plugged in and right now my oil level is a little on the high side.

My wife is on my *** to get a new truck now, but I don't want to. I love my truck and it is my daily driver(97 F250, CC, short bed, no chip). However, I am having a hard time standing up for it because it keeps dying and/or having issues.

The questions:

I pulled the wire from the fuel heater that I thought was the problem. It was on the driver side and the top most wire on the bowl. Red with a yellowish stripe on it. Is this the right wire? It fixed the initial break down and I had it taped out of the way so it would not short out again, but the truck died a second time with same symptoms.

If I pulled the right connection, where do I look next to fix the problem? If you guys were troubleshooting this, where else would you look? There is no obvious shorts in the harness, and I have a temporary fix in place that I am not proud of(I put in a 50amp fuse). I am just looking at the harness, maybe hoping the problem will jump out at me, but its not. Where do I go from here?

I feel that it was the cold temps and the lack of patience on my part to let the truck warm up that led to both of these instances. What do you guys think? Does this mechanically make sense?

Thanks in advance for your help,
Eric

 

I think you have the wrong wire unpluged. It should be the middle one.

 

The top is fuel restriction, next is fuel heater, and bottom is water in fuel. Does the sensor you unpluged first look kinda like a vacuum port?

 

Gabe is right, it's a red wire with green stripe. That should fix your problem.

 

Thank you guys for the quick response. I am going to have look at it again tomorrow. I was hoping it was something I did wrong and not something with the truck. Again, thanks.

Eric

 

No problem. Let us know if that took care of it.

 

If it was a sensor you unplugged, it was def. the wrong one. Fuel heater connector is a single wire, red/green insulation, flat blade terminal.

 

Just tell your wife you will buy a brand new one with all the whistle's and bell's. Then she will say, fix it. Ask me how I know.
