Hello Denmark, I doubt there is a problem with your ignition switch. Don't waste your time there. They ones who are pushing you in that direction must have misunderstood your original post. Also, the cold start valve is NOT located on the throttle body, it's located on top of the intake manifold. Your pic shows the hose that goes to the CSV however there is a black hose or wiring going right over the top of where the CSV is actually located so I can't see if it's on your engine or not. It probably is. Dave M's pic shows him pointing at the CSV, so go by that pic to locate it on your engine. If it's there and there isn't a connector going to the top of it then you know where that loose efi connector should go. The CSV is only going to help a cold start if the ambient air temp is below 65 degrees F, which I think is about 18 degrees Celsius. Above that the system is shut down by the thermotime switch. You're going to need to get a fuel pressure gauge that goes up to at least 65 psi and hook it up right above the fuel filter on the right side. Start the car up and record the regular idling pressure, then shut the engine off and see what the pressure is. It should be between 29 and 35 psi at idle. It usually drops down quite a bit after the engine is shut down. As long as it remains above 8 psi, when the engine isn't running then it's ok. You'll want to leave the gauge on there overnight and check it again in the morning to make sure that you still have residual fuel pressure. If it doesn't hold at least 8 psi then let me know, I sell a one way valve that you can install after the fuel pump that will let you maintain fuel pressure. The original check valve isn't available anymore.
The throttle body won't usually cause a hard starting problem however bigger throttle bodies DO NOT give you more horsepower like the previous owner claimed. The only thing a bigger throttle body will do is empty your wallet faster. My advice is to get rid of that throttle body as soon as you can. If you can get ahold of the previous owner maybe they still have it. If not I have lots of good used ones and I delete the pollution device on the bottom of them called a BCDD which will solve any future grief because all of them will eventually fail.
Hard starting especially cold can also be attributed to the valves being way too loose or way too tight, or a weak spark in the ignition system, or the timing being retarded too much. Good luck on getting your issue solved. Z man of Washington
