190e 2.6 won't start!

hi guys. i was wondering if anyone could help. i have just brought an '88 190E 2.6 auto as a non runner but it was running when it was layed up 3 weeks ago. i know the car so i know this to be true. i have heard that there is a common fault with the dizzy cap but i have checked and all seems ok and i am getting a good strong spark from the plugs. there is plenty of fuel in the car and the pump is priming when the ignition is turned on. i have cracked off the injector pipes to make sure fuel is getting that far and it is. the engine is turning over fine but it doesnt even try to fire. does anyone have any ideas as to what the problem could be? as i said the vehicle was running when it was layed up three weeks ago. any help much appreciated, cheers, mike.

I would say overload relay fuse or the relay itself... and fuel pump relay.
