For the last day or so it my truck (2000, 5.4, 4x4) stumbled if I accelerated at about 80 KPH. If I accelerated slow ran well. This morning drove to work it was running rough ,now no start does not even turn over. Starter ben****s clicks thats all. Had no codes come up, used the Snap on machine at work. So its not some cheap code tester. I don’t think it’s the starter. And a starter wouldn’t make it run rough.
If it was a coil would it not turnover. The Veh Tech and I are stumped. Im not a parts changer, rather fix the broken thing once. Any can help

 

Clean all connections from the battery to the starter and get the battery load tested.

 

I thought of that, I broke a stud off the starter anway, so new one coming. Now for the stumble at accel at 60-80 Kph?

 

That's spark plugs and/or coils.

 

I understand that, but the problem is no codes coming up.

 

They won't come up for a low grade misfire, only a hard miss.

How many miles on the truck, how many miles on the plugs, and what brand are they?

 

If you have a snap on scanner you can get mode 6 live misfire counts and that will tell you what cylinder.. Gotta get it to start first.

 

I have 249Ks and changed the plugs at 190Ks good ford ones. We had it on the scanner yesterday before the starter decided to crap out. Damn thing started good when I left for work. Then when I got here crapped. Well its looks like the org starter, not bad for 13 yrs old. Just its hard when you dont have your own tools. Yes can use the vehicle tech ones here, but they do need them.
I did have a wet miss on number 1 months ago. But dryed it up and ran good. But for the past 2-3 days that miss started. We tryed to get it to miss driving but no code.
Putting the new starter in tomorrow, it better start. For the miss ill try it again. at 80$ a pop cannot afford to replace all the coils.

 

Again if you have a snap on scanner it will tell you where its misfiring Scroll to live misfire count. It dont have to give you a code. Dont count on that starter being bad. 90 percent of the time someone has a no start situation its a bad connection. Ford starters last a really long time..

 

I thought the starter would be ok, but I snapped off a stud. So have to replace it. A lil pissed. Ill hook it back up when I get it started, its the EESC319W and extra kit is it does everything.

 

Well didnt need the tester, took a good guess and replaced the number one coil. Picked it up from NAPA 60$. Starts and runs better. Now for the etest
