Sounds like fuel relay located in fuse/relay box. This is a common problem on the 944, always good idea to carry a spare.

As with any no-start situation, you need to know if you have spark to the plugs, fuel to the injectors, and normal compression to proceed.

My 94 929 mazda won't start


You probably have a blown head gasket, not allowing you to get enough compression built to start the engine.

Rent a compression tester from AutoZone (You get your money back when you take it back) and use it. If the compression on each cylinder is less than 100 PSI, you've got some issues. The cylinders should also be somewhat balanced.

After I drive my jeep some, if it is somewhat warm or not cold weather, my jeep has a hard time starting. It may crank but run a little ways and cut off going down the road.I have had the coil, plugs, plug...


if it shuts off after running for a while and will not restart for about 10 min,a bad crank sensor will cause this. abad crank sensor will make car shut off and not restart for about 10 min. put a scanner on to make sure. a check engine light does not allways come on. if you do not have a scanner, any auto parts store will scan it for free.
