My car listed above mk3 is having an issue where it doesn’t start but cranks. New fuel pump was put in, and when I put direct power to the pump it turns on. Nothing when I turn the key. It had a Walbro 255 and the 12v mod done as well. All fuses and relays are good as well.

We need to check for spark because if the crankshaft angle sensor is not working the engine computer will not turn the fuel pump on and the engine will not start. Please go over this guide to check for spark:

Here is the location of the sensor which is inside the distributor so you can check it out. Also use a test light to check for power at the positive side of the coil.

Check out the images (below). Please let us know what happens.
