Re: 1996 Collector Edition Corvette

I just got off the phone with Holley fuel systems tech support. I posed the question is there an upper pressure limit on these Accel 150826 injectors. He said there was not spec like that that he knew of. Then I asked about the flooding of fuel into a cylinder. In my case, the #6 plug was noticeably...

Re: 1979 Malibu

Here's the pinout info for the bulkhead connector (1984 version)
I'm not sure if it will be helpful or not.

Good idea, I'll do it. :D

Re: 1996 Collector Edition Corvette

Just to get back to the garage and reality, I have a lot of work to do to get this car running again. The problem of fuel pressure not holding needs to be addressed. It appears to be a failing check valve in the fuel pump. I'm thinking of plumbing in an inline check valve to verify the theory. I als...

Re: 1996 Collector Edition Corvette

hopefully we can help shorten the repair time. I don't have a huge experience base with injectors but stuck open is not something I have seen yet. the TPS on mine is a bit out of adjustment which makes a slight hesitation off idle. while yours may not be out of adjustment it could be dirty/corroded...

Re: 1996 Collector Edition Corvette

This conversation has teased out some thoughts regarding this problem. Just before we took this doomed test ride, I had removed the throttle body and did a deep cleaning. Even though I had cleaned the throat while on the car, it was really dirty everywhere else. What if the dirty TB was the cause of...

Re: 1996 Collector Edition Corvette

That's a reasonable idea, BP, just to cover that base. Furthermore, I found this blurb from an Accel article on the web that is talking about raising the fuel pressure with an adjustable fuel pressure regulator for tuning purposes. At 58 PSI I am pushing the limits of factory fuel fittings if this i...

Re: 1996 Collector Edition Corvette

I appreciate your help Andy and I keep in mind all the suggestions as I go along toward the solution. Right now I'm focusing on the assumption that the only way all that gas could have gotten in the cylinder is by way of a malfunctioning, stuck open injector, either mechanical or because of debris l...

Re: 1996 Collector Edition Corvette

The fuel pressure is where it is because that's were it needs to be to run without the bog. That engine has been running really strong and reliably with the current fuel pressure set at 58 psi until I suddenly got the P00300 code. One thing to keep in mind, is that the engine may have been running w...

Re: 1996 Collector Edition Corvette

I spent this afternoon gathering more info on this cylinder flooding problem. I removed all the spark plugs starting with the most difficult, #8 (pass side rear). They were all wet to some extent, but #6 was obviously the cylinder with the problem. Number 1 was the last one I removed. You can see in...

Re: 1996 Collector Edition Corvette

After several long diagnostic phone conversations and some testing with Rich Jensen, we know we are dealing with two different symptoms related to the fuel system: 1) Fuel pressure not holding in the fuel rail 2) Fuel dumping into a cylinder by one of the injectors Through the process of elimination...

Re: 1996 Collector Edition Corvette

Here's are the comments I received from Rich Jensen: Okay, there's only four places the fuel pressure could be bleeding off. 1: Through the injectors but if you had the fuel rail lifted and no fuel was coming out of them, then it's not that. 2: An external leak in one of the hoses or fittings but si...

Re: 1996 Collector Edition Corvette

Maverick came over this afternoon and we did some testing. I lifted the fuel rail and then pressurized it. None of the injectors sprayed or dripped fuel. We also energized each one in succession and observed the spray pattern and then they shut off as they should. We also noticed the fuel pressure b...
