944 wont start

I have an 85 1/2 Porsche 944 that will crank but wont start, I drove it 1 day and it hesitated slightly before starting and the next time I tried to start it it wouldnt, I changed the DME and the fuel pump for powers up when the car cranks, Im not sure what to try next, any ideas?

Try the search function. This gets asked once a week and there is never enough information to diagnose such a broad problem.

If it drove one day and not the next...

Switch the DME/Fuel pump relay with your spare.....No spare make a jumper:
DME Relay Information and Testing

Top Back of the engine where the reference sensors connect. Wiggle the 2 wires. Check for cracks in the insulation. Clean the contacts.

Tighten the big ground on top of the bell housing and clean the battery connections. Put a piece of tape over the bell housing TDC Hole to avoid droping a nut in the clutch.

Fuel filter----when was it last changed?

Here are further ideas
