Hi Chris, Thanks for your response. I forgot one other thing that supports the 2.2 – 2.4 theory...
The 700 (88–) Fault tracing manual (Regina) has this for the first step in No-Start diagnosis:
"The fuel pump should pump for approx. three seconds after the ignition has been switched on."
I don't have the comparable LH manual, but the '93 Greenbook shows both FI systems, and except for external differences (like AMM vs Air Temp Sensor), the LH 2.4 and Regina systems appear almost identical.
Admittedly, it's a stretch to assume that the LH 2.4 has the same diagnostic as the Regina, but the circuit similarities suggest that it's likely.
And since I have never seen the "Key ON = Pumps Run" suggested in any published LH 2.2 maintenance literature, I see it as an occasional fluke that's become a myth.
P.S. My Regina starts after the 2nd compression stroke (or so it sounds) in sub-zero temps. I've heard there was a "Cold Starting" ECU upgrade some years ago, but you probably have that already, in Halifax (where the Volvo assemblers use red Loc-Tite on the brake hose fittings — the 900 at least).
