I just replaced the o-rings on my fuels injectors...

Simple install - took off fuel line at the filter and unbolted the rail.

Replaced the o rings and put everything back on.

Now the car won't start!

There are no leaks anywhere...

When I turn the key and prime the fuel pump the pressure goes up to 60psi then steadily drops to about 20.

The under hood pressure gauge is reading around 10-20psi at all times.

My setup is -

AEM fuel rail
Precision 1000cc injectors with GM clips
Honda resistor box with GM connector
Aeromotive Fuel pressure regulator
-6 stainless fuel feed and return lines
Walbro 255lph "HIGH PRESSURE" fuel pump


any thoughts?

 

oh yeah.. I'm supposed to be at the tune shop by 9am tomorrow!!!!

 

How many times did you try cranking it over?

 

probably about 5 times for 5-10 seconds

 

I waited a few minutes between cranks...trying not to flood it out

*sigh* so much for tomorrow's tune...

 

sounds like a regulator failing. Aftermarket?

 

it ended up being fouled spark plugs.... fuel pressure seems to be just fine once the car is running.

Thanks for your help!

 

Hmm. How did they foul out while you were changing the o-rings?

 

I guess they just got to soaked enough to foul them somehow... the car is running super rich so they could have just bit the dust before I even changed the o-rings. who knows weird **** seems to happen very often.
