thought I dig out this old thread, cos I have finally solved the problem

After changed and tested every sensor and wire in the car I`ve found the problem now.

It was the chip....have it changed now for an MSD one and it starts at the first turn of the key!!!
I think the old one wasnt developed right, cos I uses a lot of fuel, around 12liter at 100km.
Thought it was right, but in the last few days i managed 9,5 at 100km
