560SL Start Problems

I have had my 560SL for about 3 months and drive it on the weekends. Last week I ran a couple of errands, then had to take my daughter to work. The first time I fired it up it was fine. The second time it took a few seconds to start, while the third time it took 5-6+ seconds to fire and I was pumping the accelerator. The car ran fine and fortunately I got home but that was that and it has not started since. Turns over OK. I got under the back and the fuel pump activates for a few seconds when the ignition is turned on. A buddy is a paint and body guy and he thinks one of the fuel pumps is bad. I agreed with this and was just about to place an order to replace all rear fuel components (2 fuel pumps, fuel actuator and pressure regulator, and filter) when I did a quick search on this site. I ran across a thread on a faulty ignition system showing somewhat of the same symptoms. I am a decent DIY but have no testing equipment. Anyone have any ideas before I drop ~ $600 into these fuel replacement items?

If you don't get moved, you'll do a lot better if you ask this question over in the 107 forums. I have a 107 and many of the guys over there are experts on these cars.
Try here: R/C107 SL/SLC Class - Mercedes-Benz Forum

When out on the road, it's always best to watch out for Pot holes, Sink holes, and those other Holes!

You can't get us confused. I'm also "Nice", but NYYYCE is NEVER "Easy"!

Thx. Didn't realize there was a 107 forum section. Just moved it over.
