Cold start procedure for the 2001, 2002 and 2003 series involves full throttle then pull and release the engine
stop cable a couple of times. Result is the FIP rack is opened further than full throttle to allow extra fuel
to be injected.
During the summer with warm water and air temperatures no problem. However, Southern England
is 50.N so during the depths of winter with water temperatures around 5.c and air temps at 0.c the volvo
is sluggish to start. We even group together the engine and house batteries which turns the engine over a little faster. However, we also marvel at how a tiny squirt of oil or ether fires the engine straight up rather than prolonged session on the starter motor
trying to raise the cylinder temperatures enough to fire the old beasty up first thing in the morning. Subsequent starts even during winter are not a problem.
Other options, well we have had a head
job done so no problems there and repowering at £7k isn't an option at the moment. Since the engine is 23 years old a squirt of WD40 isn't going to harm it.
