A cheap tire pressure gauge of the stick type can be used to check pressure using the fuel rail Shraeder valve. Turn the ignition on to 2 so you can hear the pump prime (hopefully!). Then test the pressure. Not really accurate but if you see say 36psi or higher it should start and run. It will ...

Since my wagon is 1995 model so it only provides the OBD-I interface in ...
