I also can hear that fuel pump winding...how does the relays in the glove compartment work...will they affect a cold start?
Not if the fuel pump is operating. It is more likely the Ecu is not getting the temperature data from the engine block temp sensor. There are usually two temperature sensors on the block. One provides temp to the dashboard temperature guage. The second, the most critical for cold start, provides temp data to the Ecu which determines the cold start program. If you are a DIY you need a repair manual, if not now later. Auto repair stores may have, your library may, or filepeep.com if they have it, or
manualslib.com. (Make model year) It will show where the block temp sensor for the Ecu is. It may need to be replaced. However I found on my 20 yr old auto that corrosion had compromised the data and caused a very rough, difficult start. I cleaned and scraped the connecting parts to bright metal. Reset error codes and Instant start, just like brand new. So double check for clean connections first. You may find it very difficult to access the connections. Thus the need for a repair manual.
