Took my 1973 911T 2.4L with CIS out for a drive this morning everything was fine.

About an hour later went to move it, first try wanted to start, second try nothing.

When I turn the key gauges fire up but I can't hear fuel injection/fuel pump.

Checked all fuses (front and back all good).

Anything else I can check before towing it in to get checked out?

Thanks
