Re: start then dies everynow and then

Check your injectors and fuelpressure.
Its pretty common that the injectors go bad.
Especilly the multec ones...
Measure them and see how the ohm goes... it should be around 12-16 and they shall be near eachother.. Even if the ohm are good, the injectors may be bad..
Then you need to have a fuelpressuregauge and see if the fuelpressure holds up when the pump stop priming...

Call Jon at Fuel Injector Connection. He sells Bosch III modified for our cars (http://fuelinjectorconnection.com/sh...productId=134), direct fit and they have a great spray pattern, best on the market, they cost 169,95 and have 3 years warranty..

Phone : 770-888-1662
Email : info@fuelinjectorconnection.com

I had the same problems, stopped sometimes when not giving throttle, and had to crank over and over... changed injectors and the problems went away.
So I would call Jon up at FIC and talk to him.. And he will help you out.

You can call him and talk to him, and see what he says.
That dosent cost anything (exept localtaxes for the call)

Jon is really nice and he will help you out.

Keep me posted about this problem and how it turns out for you

I thought it said 350 in your info to the left, and 327.
It will work, maybe you need to lower the fuelpressure a little.
But call Jon up and tell him your info and he help you out, he got alot of injectors

Re: start then dies everynow and then

i don`t think they will, it`ll lean out your 350 too much, 350 injectors are 22lbs and 305 are 19 i think.

LT-1 injectors work.

but yes look at your injectors, when the car dies also see if you can touch the computer, ground yourself out though, if it`s hot, you probly have a bad injector/s
