I removed all of the solenoids on the intake. I checked the codes and I got I think seven of them all relating to the solenoid valves. But now the car won't start. After I put the intake back together the motor was extremely flooded, but I went through the unflood procedure but still no start. Since there is no longer a solenoid valve for the fuel pressure regulator, I just ran a vacuum line from one of the unused nipples on the middle intake (one of the two along the firewall side). Do any of the codes refering to the solenoids or air control valve have the ability to prevent starting? I guess I could have an intake leak; but the car should still start right? I also disabled my OMP and am running premix now, but the OMP is still on the car and functional, it just doesn't have any lines hooked up to it, and the internals are disabled. I did not get any codes for the OMP so I assume it is functioning correctly. I also may have added to much premix; since the car had a quarter tank of gas with no premix added, I added about 6 ounces of premix. I'm not sure exacly how much gas was in the tank so I added a little extra oil just to be safe. Can an overly oiled mixture prevent starting? The air pump is still on the car to power the aux ports and the VDI via a custom set-up independent of the rest of the intake. Is there any obvious reasons why the car would not start? I'm up for any suggestions. I really only farted around with it for about a half hour, so it may be something stupid that I forgot to hook up. But I figured I'd ask you guys first, just to see if you notice something I don't. Thanks!

 

Did you cap all the vacuum lines? If you didn't, you probably have a massive vacuum leak from all the fittings that are now open.

Running the vac line from the FPR to the engine probably won't cause the issue you're having.

That doesn't sound like too much premix, I'm running 13oz to 5 gallons (roughly 50:1) and that's running fine.

Do you have fuel pressure? Spark? Timing set correctly?

Got lots of fuel. Got spark. Got compression, according to the whooshes method. The car started fine and ran great right before I removed all of the vacuum lines. So the spark and compression should be fine. I'm thinking either too much gas, or a huge vacuum leak, like you said.

About the premix. I had read that you should mix one ounce per gallon. Is this incorrect? I deffinitely don't want to run dry on oil; but I also don't want to overdue it either.

 

I'd start with the fuel pressure solenoid. Wow, that's a lot of cleanup to do all at once..
