Re: Injectors won't fire ONLY on the first start of the day?

My assumption is your cold start injector is not working and the starting fluid is providing the fuel necessary to start the car. After the first start there is enough fuel in the intake and heads to...

Re: Ethanol vs. Straight Gas

That is what I hear but I can only tell you that all cars after 1986 were designed to resistant to 10% ethonal in the fuel, so they should be OK.

Re: Springs for XFI280 cam

Do not use the 986-16 spring, it does not have enough lift capability. The valve lift .576 and you will be under .050 clearance with a 1.75 installed height. Near or at coil bind.

Re: Fabricated stock TPI intake on an LT1?

I respectfully disagree, keep the 1997 computer and use Jet dynamic tuning software to tune it. It works well and you can scan it with HP tuners, or others.

Re: Low oil pressure cold start

Injector firing is not related to oil pressure. My guess is you need a new chip to add in additional cranking fuel to help it start quicker.
