Well, the title just about says it all...
2001 S60 T5 LPG converted (BRC Plug & Drive), 150000 Km.
Started to have difficulties starting ii the morning a few months ago.
- Cranks for exactly 7 seconds after sitting overnight, then runs perfectly.
- If I turn it off immediatelly after starting for the first time in the morning, it will start right away, perfectly normal; as will it for every subsequent times I start it (I assume this rules out the engine temperature from the equation)
- If I let it sit during the day, it will crank in the proportion of the amount of time I let it sit. My impression is that this characteristic is getting worse... In other words, a couple months ago, letting it sit for 1 h would resulta in an almost immediate start. Today it resulta in a 2-3 second delay in cranking time. Still, the biggest delay it will get is exactly 7 seconds.
- The car pulls like an express train, idles perfectly and behaves, otherwise, perfectly normal.
I had trouble with a top-leaking original fuel pump in the past. Solved it with glue for 3 years, but as this issue appeared, I assumed it would loose fuel pressure through the fuel pump when sitting... So today replaced fuel pump for a new BOSCH unit... problem is exactly the same.
Running out of ideas... Can continue with the lottery game of replacing parts, but woud like a more focused approach..
p.S. Never in this period of time has it thrown any CEL. VIDA doesn't have DTCs...
p.S. 2 Car is LPG converted... but as it won't start on LPG, can't really use it to help on troubleshoot...
p.S 3 the Battery is very good (VARTA), brand new
HELP, please?
