I swapped my Fuel Injectors on my 1992 Toyota Pickup 22re and now it won't start. It started the first 3 times but was running a little funny. Now it will turn over but dies when I hit the gas. I used high performance replacements. Could that be the issue?

 

So, your vehicle worked.
You put in different injectors.
Now it doesn't work.

You should draw this out in a flow chart. it'll be pretty straightforward with no branches

 

Why did you change the injectors?

 

I changed the injectors because while changing the head gasket last summer, I accidentally dropped one of the original injectors in a vatt of used oil. I fished it out and cleaned it like crazy. I also put new o-rings in for the injectors when I was putting it back together. The o-ring kit didn't come with the little cap replacements for the spray end and 2 of my originals had damaged caps. We went ahead anyways, because I was in a small mountain town and couldn't get the caps we needed. After all the work, it started having an issue so I pulled off to take a look and there was gas leaking from one of the injectors. I was able to twist them around and make it stop, and have had very little direct leak issue since. However, the truck ran really rich since then and would have troubles restarting if you had driven it too recently. I couldn't find just the replacement caps when I searched so I figured I just had to buy new injectors to get them. I also figured the one I dropped was staying open. Hence the richness and flooding.

 

Check all the vacuum lines and ground wires. If it is running that rich, something got knocked loose while working on it. Check the intake boot really close also for leaks and cracks

 

Maybe try cleaning your old injectors in an ultrasonic cleaner. They do work well. You can get new spray caps off eBay. If the injector was leaking out the body externally I’d say they’re history and retire, but if they’re bleeding out the spray nozzle there’s an excellent chance a good cleaning will correct. Replacing the seals and cushions that go on the injector between the rail and head is always proper when installing injectors. Make sure not to use any lubricant on them other than gas.

 

Thanks for the insight. I am just going to go ahead and order and replace all of the vacuum tubing. I also found a replacement for my cold air intake hose that had torn, so we replaced it with a rubber dual clamp plumbing coupler. I will also ask the mechanic behind my shop if he has or knows where to get an ultrasonic cleaner and potentially swap back in the OEM's. Once I get those caps in anyway.

 

I sent mine in to get rebuilt and cleaned, looks like the company I used is no longer in business

 

Buy the oem seals. Replace seals.

 

You mean the injector o-rings and caps?

 

No,ev13wt is referring to something a little different. The o-ring yes, but two other seal cushions are involved. Besides the o-ring that goes at tip of the injector, you also have two rubber cushions/seals at either end that keep the injector snug between the rail and the head. It's recommended all three be replaced whenever the injectors are removed. Those are the ones I was saying not to use any oil on when installing, just gas. The fact you had an external seep, and fixed by rotating the injector, would let us believe those cushions are probably compressed with age and not keeping the injector tight. Engines can tolerate a lot of different leaks spraying on their surface, but gas isn't one of them. Getting the oem cushions wouldn't be a bad idea.
Here's an image of what we're referring to(23250B, and the cushion seals 23250C, and 23291):
