Re: Cold starting problems!!
Welcome to the forum!
Check the fuel pressure, it MUST be a MINIMUM of 60psi while the pump is running and the engine is off. Last edited by old_master; 01-10-2007 at 09:41 PM.

Re: Cold starting problems!!
I had a similar problem.....search for my post. In a nutshell, there was no 12VDC on the pink wire of the ignition module. I determined that it was the "computer." "Rigged" fix was to put a toggle switch between battery and pink wire on ignition module. Just flip switch on to start when it is cold. Don't forget to flip it off after starting or you won't be able to kill the engine with the key. Get that voltmeter out and start checking for voltgage. Good luck.
