I installed my Vishnu Garrett turbo, Vishnu EcuTek Stage 2 (mapped for vf22, larger tmic, STi injectors, up-pipe, and turbo-back), and Perrin Fuel Rails.

I'm still using the stock injectors and I can't start the car. Could the stock injectors be the problem or is it the engine management?

Much Thanks!

 

I've more than doubled checked the vacuum, fuel, and oil lines.


The car cranks, but it just won't start.

 

Are you getting fuel in the cylinder? Spark? Is it a slow crank? The engine management shouldn't matter at all just getting the car started (well the tune shouldn't, if the ECU is fried/damaged of course it would matter, but... ). Did you make sure all of the connections for the various sensors are plugged back in? Crank position? Cam position? MAF?

Dude, I just totally missed the part of your post that said that you left the stock injectors in the car!

While the vehicle should still start up you do NOT want to get any boost into this thing!

You're running a REALLY mis-matched combo right now... You're not planning on driving the car around for very long this way are you?

IIWY (If I Were You) I'd wait until your injectors showed up before I buttoned it all back up.

It cranks normal. I'm just not sure if I'm getting fuel.

I just looked at the Perrin site again. I think I aligned the injectors wrong.

It was hard to place the injectors back to it's prior position (connectors facing away from another). I placed the injectors with the connectors facing out and away from the engine block. Hopefully this is the problem.

I'm trying to find pictures of Perrin fuel rails that are installed with a view of the injectors.

Thanks for helping Rich!

 

My car has been at my friends house for over a week. I feel bad because I told him I only needed to keep my car parked there for a few days, but I did not anticipate a national backorder of the injectors I need.

My car is at Ewa beach and I live in Kalihi. I was palnning to drive on the backroads without hitting boost. Is this too risky or should I wait and push my car on public street parking until my injectors arrive?

 

On second thought, I'll wait.

Thanks Richard!

 

I'm not sure how the Ecutek compensates for injectors. If it "takes over" and doesn't allow for normal closed loop stoich fuel learning you're going to be running REALLY lean. I wouldn't chance it. If it does the same thing as a piggyback you SHOULD be fine if you stay out of boost.

Not having a garage sucks (believe me I know!)...

I'd talk to Vishnu before driving that car.

However as long as you stay out of boost (COMPLETELY) you SHOULD be okay if you MUST move the car.

You're welcome.

BTW, don't the stock injectors have a symmetrical spray pattern? If so then alignment shouldn't be too much of a problem. Just starting the car doesn't take an accurate shot, it just takes a decent amount of fuel...

Are you sure all of the connectors for the various sensors are plugged in ALL the way? Sorry for beating a dead horse but if you get a normal crank and it doesn't sound like there's ANY hope of it firing (no modification of cranking speed, coughing, lope/bubble sound at compression/cranking) then it's usually electrical and that's usually a sensor or maybe even a popped ECU fuse or something...

I think I may need someone to double check my work. I've rechecked the intake manifold area and rechecked the fuel pump.

I'm certain that the fuel pump is correctly installed, but I'm having doubts with the connections at the manifold area. I've also noticed that there is a lot of play with my injectors that are installed with the Perrin rails.

For my EcuTek, is it possible that I check if it works by plugging it in someones Stage 4 WRX?

Anyone want to try my Stage 2 EcuTek? *big grin*

Did you have to remove your intake manifold to do the fuel rails?

What connections are you speaking of? Electrical? Vacuum?

Do you hear the fuel pump priming when you turn the key to the on position?

Pull a spark plug after cranking the car for a while and see if you have fuel in the cylinder...

Do you have a spark tester that can handle the high output of the WRX's coil on plug ignition?

What does the cranking sound like? Normal? Does the car even attempt to fire "sputter" or "gurgle"?

Do you have any fuel leaks? I don't know a thing about the aftermarket fuel rails so I'm not going to be much help there.

Did you disconnect the cam and crank sensors to prime the turbo as is recommended? If so, are you sure that they're FULLY seated (CLICK!)?

I'm sure you changed to colder plugs during the install as well.. Did you make sure to gap the plugs ~.028"?

Just read your reply closer and saw that the car is cranking "normal".

I'd crank it for a while (you probably have already done a bunch of that!) and pull out a spark plug to see if you can smell a strong raw fuel odor. This'll at least tell you if gas is getting to the injectors and into the cylinders.

For it to crank normally but there be NO firing it sounds spark related. It could also be a totally lean cylinder if there's 0% fuel delivery...

Pull the plug and let us know what you get.

does the car start with the stock ecu?

 

I think he had the Ecutek re-flash done so there might not be a stock ECU to try.

the ECUTech is programmed for STi injectors....
that would cause the stock injectors to shoot very little fuel... sounds like you are going to be VERY lean if you aren't already too lean to even have the engine start...
