Split Second Engine Cut Off with Dash Lights
Hi All!

I've recently encountered this little hiccup. When cruising along or sometimes idling, the engine feels like you did mix the clutch right to accelerate and the engine "dies" for a split second then is on again. When it comes back on, the glow plug light, oil pressure light, and sometimes the battery light is on for a second or two before everything returns to normal. It was scary at first, especially on the highway at highway speeds but not it's kinda annoying and I feel that I should nip this in the bud before it will eventually get worse. Anybody experience this or know what's going on?

Thanks.

Check that the relays under the driver's seat are really tight in their sockets. This, and starting problems, can be caused by poor connections to these.

Hi andydef90,

Where do I find the earth straps? I've been meaning to check them but I don't know where to find them. Tried researching on here but I haven't had much luck finding the info.

Hi blackwolf,

This is something I haven't done yet but I did check them a week or two ago when I was having some issues with my electronics. Time to check them again, I guess. Will advise if it helped any.

Thanks!

Hi All!

Just an update, check all the relays - all good. The truck had to go get some body work done and had the earth points checked. After pick up, the truck was cured so I guess it was the earth points like andydef90 said.

Changed oil and all filters just to be sure.

Looks like I spoke too soon and jinxed myself. Sad

It happened at least thrice last night. Big Cry

Anyone have any other ideas?

Also check the terminals on the battery itself.
I had an issue recently where I also thought it's an earth issue.
Checked everywhere and even though the Negative terminal seemed tight it wasn't really.

After tightening it properly with a spanner my problems were sorted.

Also make sure the battery cannot move inside the box, I've also had it where, due to corregations, the battery positive touched the side of the box and then also caused the engine to cut out.

Hah a similar issue on a 2013 2.2, it turned out to be loose connections on the back of the ignition barrel.

A quick fix with a dob of solder Very Happy

Thanks for the clues and tips! Thumbs Up

Will look into them and come back to report the result and hopefully not jinxing myself anymore. Mr. Green

Hi All!

Just a little update:

The ignition switch is properly plugged. So far,, all the earth points seem secured and connected. Recently had work done on the AC compressor as it stopped working due to a dead magnetic coil and it needed new bearing but a little bit of machine work on the pulley. While leaving it to run, it was noticed that the hiccup, when it does occur, coincides with the compressor kicking in. The hiccup is very pronounced now. While I think the compressor thing is kind of a coincidence, as the hiccup does happen when the AC is off, does this little bit of info help narrow down the problem and how to fix it? Question

D you check the battery terminals. Not just tight bolts but actually tight on battery?

Good luck.
