No power at all on pressing accelerator

I have the same problem and I have a Opel corsa 1.3 98 model the Ne engine. I have a similar problem with my car over fueling no revs when I start it. In the morning it would start easy but still jerk and in the afternoon when I leaf for home it takes a lot of cranking before it starts and during starts it will back fire. so I started with service and when that did not help replaced all the sensors then the T-bel (I Have Double checked my timing and is Very sure that it is right) Replaced crank gear, crank pickup, coil, plug leads tested and cleaned my injectors and intake butterfly. replaced the fuel pump relay and fuel pump.After all that it ran sort of ok for a few day's and last night it acted up again checked my plugs an sow it's black as night replaced them wit new ones, so after that it starts but does not rev up. After a few min running the exhaust manifold become extremely red so I switched it off and towed it home. I have a OBD 2 Diagnostic tester but can't seem to get it to connect to the Car's computer,because the check engine light is on. This exercise is starting to cost me a lot. Any Thoughts on where else I can search for the problem. There is no holes in the exhaust and the car is defiantly over fueling. I also get some oil in the intake from the tappet cover and think that might also be part of the problem. I also found that the Fuel relay Became extremely hot some times. So I have checked the earth wires on the engine but all is ok there. Hope this Is enough info For someone that can Help Please it's not my best car It's my Only. Thanks so far have a nice day All.
