Hi, for five years now my Corrado was sleeping in the garage. Last year I had time to work on it and tried to put it back on the road.
When I tried to start for the first time my engine, it was cranking, but wont start.
Finally I found that it was the fuel pump that was dead.
I went in a speed shop to order a brand new one and tried a second time my engine. It was runnig good at iddle, but had trouble at WOT.
So I read the FAQ's and tried to find why I had this trouble.
After all, I did a big tune up, change the rotor and cap, blue, black sensor, plugs, all vaccum and the one to the ECU 1m long, fuel filter, and spark plus wire and the air filter and some other things.
I checked to make sure that all wires in the engine bay was in good shape.
After all, the trouble was always there, runnig find at iddle, but no power at WOT.
Finnally, I did a fuel pressure test and had 3 bar of fuel pressure, so my FPR is a 3.5bar
I called the guy who sold me this fuel pump to have another one and now with this new pump I have 3 bar fuel output at the fuel pump.
I did the test putting the gauge at the output of the fuel pump, so I dont understand why nthe pressure is so low with those fuel pump.
I dont know the brand of the fuel pump, but when I read in the bentley it's look like it was two models of fuel pump for the corrado, one with two fuel pump and another one with one fuel pump in the tank!
The one with two fuel pump is supposed to give 3 bar and the model that I have with one fuel pump in the tank is supposed to give me 4 bar at the output of the pump!
I'm not a mecanic, and the speed shop tell me that the fuel pump is supposed to gave me 3 bar of fuel pressure at the iddle and the pressure was supposed to be higher at WOT. I asked the guy how the fuel pump was supposed to gave me more pressure at WOT if the voltage at the pump is always in between 13-14V and he did'nt gave me any reasons.
So I want to know if it's the good way to do the fuel pressure test, my fuel tank was open and I put the gauge at the output of the fuel pump with a T fitting.
Help me please, I want to put this bitch back ont the road as soon as possible!
Thanks!
Phil
