Why does my Mercedes 380SL take so long to start?
Why would a Mercedes 380SL take about twenty seconds to start every time the key is turned despite changing the warm up regulator? This could have something to with the fuel pressure. To begin with, the cold warm up regulator pressure is because there won’t be enough cold enrichment if the pressure is too high.

What was the problem with the 1985 380SL?
The ’85 380SL had Bosch Platinum spark plugs–replaced them with NGKs. Intake, timing, and flow have all been monitored–no apparent problems. The diaphrgam and its “control arm” (if you will) sometimes get sticky/stiff…but not consistently. Fuel pump and fuel pump relay have been changed. Coolant sensor has been changed.
Can a W126 engine be swapped for a 380SL?
When W126’s were fairly common in the JY, I passed up a 500 Euro engine with <90 K miles there that wound up in the JY only because of fuel problems that the owner couldn’t solve. I had no means to pull it and get it to my house A 420 long block from a W126 would be a bolt-in with the parts off of the 380 and would get you a bit more power.
What kind of engine does a 1983 380SL have?
1983 380SL, ivory/dk brown, 46k miles, dual roller timing chain. 1986 560SL, red/white, 190K mile. I had given this some thought in the past too but never found a 500SL motor. I just went ahead and had my single timing change converted to dual roller.

How does the warm up regulator work on a Mercedes Benz?
If your acceleration is muted the warm up compensator may be broken or on its way to being kaput. The warm up regulator increases the fuel flow making the flow richer. The warm-up regulator applies opposing pressure on the injector pins of the fuel injector.
What happens to the warm up regulator when the engine is cold?
When the engine is cold the warm up compensator reduces the pressure applied, which allows more fuel to flow to the injectors. As the warm up regulator heats up the pressure is increased.
What causes a warm up regulator to fail?
A warm up regulator failure occurs when there is a loss of pressure available from the warm-up compensator/regulator. Before you do any work on your car it is important that you wear safety glasses, work gloves and dispose of all fluids in a safe manner.
