Injector Pintle Cap is broken, what do I do?

It's my fault, I left the injectors where a child could get a hold of them while I was working on the car, she did, and broke the pintle cap when it fell.

Will the injector still work without the pintle? Can I get just the cap? Any Idea where?

Thanks.

Although I have heard you can run without the pintle,(don't quote me on it.) you can get any parts you need from www.mrinjector.us pretty cheap.

that's what I'm interested in, can I run without it. I need to get the car back on the road ASAP.

yap. it wont hurt anything.make sure you remove the o-ring so it wont fall into the engine if there is one right there.

Awesome, both the O-Ring and the other plastic bit? Or just the o-ring?

OK. i just looked into this a little further. Running the injector without the pintle is not advised. without the pintle,the o-ring has nothing to hold onto.it will slide into your manifold. the o-ring to the fuel rail is the most important of the 2. without that one,fuel will spray all over your engine.BAD!
without the pintle o-ring you will have a nasty air leak to the manifold.you can still limp about with a missing pintle cap,but I suspect the car might not run very smoothly. sorry,didnt mean to mislead you with my first post,been awhile since I sorted out my fuel delivery probs.... mr.Injector.com,is your best bet for new caps.I bought my kit from them for around..$20 bucks or so...give or take..

...suggest you go to a larger auto parts store and get *one* injector to replace the banged one; you can sort out the other issues later.

...and a note to the rest of you -- **never** leave anything in reach of a small child that (a) can not be used as a toy by them (b) will harm them if put in mouth. Reach includes aided by nearby/movable stool, chair, pillows or what have you.

Ever.

This is not a scold - just a reminder that I wish I'd had as I was raising my kids, had no serious mishaps but near misses for sure.

Peace out.

True that Albert, and it was a lesson well learned, years ago. I should have pointed out, she's well past the age of putting things in her mouth. She actually put it in a pot she pulled out of the cupboard and was busy "Cooking it for Daddy."

Now to find an injector, the local parts places want $200 for one, and I hate buying stuff from the internet. Being in canada makes it more frustrating.

What other cars used these injectors? Could I get on off of any Mid 90's GM or would it be specific to the supercharged 3.8s.

You can get it off any car that had the 3800 S/C engine. you will need to get an entire injector out a junked car.the pintle alone will not come off without breaking.
there has to be someway to find a used injector around your way right?

I found remanufactured injectors on RockAuto for about $37 shipped. They have worked well for me so far.

Sure, and to Canada you're looking at double that. (I checked)

Other than the wreckers, there isn't anyway to get them locally, not at a decent price. I live in a fairly small town.

$200 for -one- injector? Owtch. THey are cheaper (~$150.-) at the dealer (in the US). GMPartsDirect only wants US$82.- for a new one.

The injector in a cooking pot is just plain *funny.*

RockAuto's a good bet for that injector if none of the wreckers in your vicinity have any. Even though they are on the internet.

I'm sure you'll get this squared away.

Car parts are crazy expensive in Canada.

To clarify, any 3800sc from 94-95. The others are 32lb injectors, the 95 uses 29lb injectors.


Trevor, I have a full set of 6 injectors that I got with a supercharger. You can have all of them if you want. I've never run them, so I dunno how good they are, or you might be able to try salvaging a pintle off one. If you PM me your address I can ship them to you. (or as said, could get parts from mrinjector.us pretty cheap. Or even just ship them all your injectors to get rebuilt for 14$ each. I had the main set on my car sent in for a rebuild and have been very happy with them. Very fast turnaround time.
