Disconnecting Port Injectors?

First post here, been around cars and trucks for a long time. We seem to have a pack rat at the house, first getting at my BRZ, and now the Tacoma

Started up this morning rough, long crank and a dead miss. CEL and Trac lights on immediately. Pulled the code, found p21D4, cyl 6 injector open circuit. Pulled the intake and sure enough, both wires to cyl 6 port injector are chewed right through.

Now the real question, there’s a small harness on the 3 left bank port injectors. I would love to replace that harness, but I can’t get the connector up past the fuel rail. Do I have to pull the rail to get the connectors off? Seems silly, but I’ve seen worse done by those darn engineers.

Any guidance?

 

Sorry no guidance here but how did that wire get like that?

 

Pack rat. Like a mouse but 10x the size. Destructive little guys

 

Welcome to TW. No help on getting the wire out, but there are ways of keeping the little... in this case large varmints from doing this in the first place.

 

Im going to have to look in to something. We bought this house a year and a half ago. Never had any problems. Last week I lose the reverse signal in my Subaru, this week it’s the Tacoma.

Probably won’t bother getting at my 83 4x4, he knows it would be too easy to fix.

.308 seems like overkill, neighbors wouldn’t be happy.

 

Cayenne pepper in a spray bottle with some water.
Take a search around here for rodent protection.

 

Well that sucks. Hope everything goes well. Luckily I get to park in the garage all the time

 

Your going to have much bigger problems if you drop those bolts down intake holes, I would advise some paper towels in intake. Not sure how to keep rodents away ? Put a cat in garage.

 

This will kill everything in the neighborhood

 

Those bolts aren’t going anywhere. Seen more horror stories of rags getting sucked in than bolts dropped in my 15 years of wrenching.

Cayenne applied. I set out some of the pet and kid friendly poison traps last week, doesn’t seem to have helped. Can’t go killing cats or any local children.

Repaired and reassembled. Started right up, code is cleared. Got a good test drive in (to pick some cayenne the wife won’t miss) and no issues.

I really don’t want to pull that rail and reseal the injectors. The intake comes off in 5 minutes. The harness would take 30 seconds if I could get the connectors off. At least port injectors are easy, DI injectors are a pain.

 

Service manual has you pull the whole fuel pipe with the connectors still connected before disconnecting them.

 

That’s high pressure, DI injectors. I’m on the port injectors, uphill a bit.

I can release the connectors, but can’t slide them up enough to come out.

 

Based on my limited experience in cars, that black thing on top of those square holes is for the air intake...I may be wrong but I guess is the air intake.
If the only thing that gets in there is clean air,...why is oil residue on the intake ports? Could be from the PCV and blow-by gases and oil vapors???
Were are the oil-can-catch haters now???

 

There’s oil in the intake of every car now. You can dump the oil out of an m276 Mercedes intake. Just how it is these days, ventilation systems aren’t just a hose and a pcv valve anymore.


The harness is NO. 5 Engine Wire, right in the middle. The rail is flat steel, it blocks the connector from coming completely off the injector.



The service manual says to remove the rail, remove the injectors then unplug them. It’s so so close.

Where in Oregon do you live? I've never had an issue like that although I've seen huge rats in the West Salem area a few years ago.

 

West Eugene. Our neighborhood backs up to a wetland area, all kinds of critters running around.

In Montana the rabbits tore everything up, these guys really get in there. The harness in the Subaru was chewed through behind the brake booster. The repair on the Tacoma wasn’t nearly as bad.

 

Did you ever find out the part number of that particular harness?

 

Hey, I know this is an old post but I am pretty sure I just had a squirrel chew through the exact same wire harness on the other side of the engine. Did you have to pull the port injector fuel rail to get the connectors fully off? Hoping to do this job next week without taking the intake off as well. Can you confirm what the part number was for the harness you bought? I am trying to order it through toyota and believe it is #82125-0E020.

 

Rat poison literallt kills everything not just rats and mice and will kill the animals that find and eat the dead ratsband mice even peoples pet dogs and cats. Don't use it.

 

I usually mix peanut butter, baking soda, and powered sugar together and roll into little balls, kills mice and rats pretty effectively.
