I got rebuilt fuel injectors from FIC, 3 year warranty. I belive it was 185ish shipped. Really hope we can figure the issue out.

 

you WILL get it

 

Sure sounds like water got into the gas tank from what you've described. There's a water drain that sits slightly down from the fuel tank cap, I would check to make sure the drain is clear and flowing freely (mine was plugged, which allowed water to periodically enter the fuel tank).

Since yours is a '92, you'll have the ALDL connector instead of the datalink style connector. I tell you this because the next time you need to drain your tank, you can disconnect the fuel feed line at the rail, run it into a bucket, and supply 12V to terminal G on the ALDL connector, which will turn the pump on until you remove the 12v source, and that way the pump can empty the tank for you.

As far as the pump priming with the key in the ON position, if the key is cycled off, then back on, and less than ten seconds has passed since the pump primed the fuel system, the pump should not prime again. Typically when I take a fuel pressure reading I will turn the key ON, then cycle off, count ten seconds, and cycle ON again. I will do this three times. That, at least for me, tends to give me what I consider an accurate reading.

I am rather puzzled by the fact that you have replaced both the regulator and the fuel pump, and are still seeing a slow drop in pressure on your gauge. This, to me, is indicative that those "new" injectors may be a little worse for the wear already, especially after having old, potentially very watery gasoline sent through them followed by no use for two years.

It's been mentioned on here to pull the injectors and watch for any leaks with the pump running. This will probably be the easiest way for you to confirm a failed injector.

You can put 12V to the G terminal on the ALDL to watch for leakage. You should not see a single drop coming out of the injector.

Please keep us updated, I hope you get something figured out.

Edit: forgot to ask, have you pulled any spark plugs after it stalls and checked their condition?

 

I am going to try some stock LT1 injectors a friend of mine has and if they seem to cure the issues I will probably get some FIC injectors and use the others as spares/buck up in case someone I know ever needs to try some.

As far as plugs, I am sure they need to be replaced, and already have been shopping for them. The plug wires are virtually new but j found kne that has a kick in the rubber, not sure how it got there, but at least change out that plug wire.

Not going to touch the car today. Too much other stuff to do.

 

Some stock 24 lb injectors are on their way. A friend of mine up north is sending them to me. Going to flush the system a bit more and make sure only clean/fresh gas gets to the injectors. If this doesn't work I am back to square one. The injectors should be here Thursday.

 

FYI: Stock 1992 injectors should be 22lbs, not 24lbs. It would require tuning the PROM to use the bigger ones from what I know.

 

Yes and no. I am sure GM doesn't tune perfectly for the injectors. Remember, they make the car to be operational in the coldest, warmest, dryest, most humid conditions. In short, GM tunes are crap. Lol going from 22 to 24 isn't enough to say so and if it runs a little fat the computer should be able to compensate but its not enough to say so.

If you would have seen the tune my 2013 had on it from the factory you would shake your head. Talk about leaving power on the table.

But yes, they should be 22 from the factory, though some guys tell me their car had 24s from the factory. Who knows. Lol wish I had the stockers but the ones in it are like 23.4 or something. Look like Accel but i can't be sure.

 

I am not sure that performance will be affected much , but MPG will be.

 

You are probably right. Honestly, if these are the final fix I will buy new matched injectors.

I might buy the tuning crap and do a little modding.

 

Haha! Get it started first huh?

 

Yes, sir. Haha

 

The injectors my friend sent me are at the house
Let us pray that these fix the issue.

Dear lord, 8 lb, baby Jesus, sitting in your bed, looking at different shapes and colors, please let these injectors be the missing link in the chain of this 1992 Corvette roaring to life. In your name we pray. Amen.

Nailed it.

 

Corvette gods, help this Vette stay running.

 

Its alive! It's alive!

Cleaned out the fuel lines, swapped injectors, got the air out of the lines, a little starting fluid, and it started. Idles pretty smooth but you can tell it hasn't ran for quite some time. Lots of nasty smoke at first but its clearing up.

Hopefully that's the issue. The throttle seems to.have a little play, going to fiddle with that too.

 

Hooray!

 

 

Small coolant overflow. Thinking they never had the chance to bleed the system after the water pump install.

 

Ok. The car gets up to temp and the fans come on but the upper tank gurgles pretty loud and the lower tank will overflow.

How can I bleed this thing? It "seemed" to have good pressure on the coolant pipe.

 

My 94 has two bleeders but I just jack up the right rear end and let it bubble out. Might take a good look at your cap might need a new one.

 

Cap has a nice rip in it. Thoughts?
