    Probably will just get it towed to the shop tomorrow, but my '84 Mondial cab had actually given me nearly 12 weeks of trouble free motoring this summer, and life was good. I drove to work, drove home that evening, and parked in the garage. Next day, cranks but won't start. I charged up the 1 1/2 year old battery (not sure if it was low to begin, maybe because I suspect the car has some alternator issues, but I cranked it down pretty good due to general aggravation) which had worked 100% of the time with start-up problems before the battery was replaced, still cranks but doesn't start. Tried to jump it, cranks but doesn't start. Tried to roll it down my driveway and push start it, doesn't start.

    Any ideas before I turn it over to the pros?

    Thanks.

    First thing to do is make sure the fuel pump is coming on. If it isn't, and the fuse isn't blown, take a jumper wire and bypass the fuse. If it works now, you have some bad contacts in the fuse block.

    If that doesn't work, there's a myriad of other things that could have gone awry.

    Let us know what happens.

    I'm NOT a technician/mechanic, so this is general advice....

    Have you checked the fuses or relays? Have you pulled the plug wires to see if you're getting spark (place close to the block to see the arch while someone cranks)?

    To me, sounds like something shorted out (over amperage?), blew out (a fuse) or just disconnected (hit a bump and fuel pump lead came unscrewed?).

    Worth a shot to give the electricals a bit of research before taking it to a mechanic.

    Thanks for the advice. Fuses are fine. Battery is 18 months old, didn't think that was the problem at first although I probably drained it down pretty good, didn't respond to recharge. I'm off to swap around some of the relays and have a peek at the fuel pump before the tow comes!

    Go to an auto parts store. Purchase a $2 can of starter fluid. Spray the starter fluid into your air intake liberally.

    Crank the car. If the car starts. Good. If it starts and then dies as soon as the starter fluid that you sprayed into the intake is gone, then you have a fuel problem (e.g. fuel pump, relay, fuse, etc.).

    However, if the starter fluid makes no difference (i.e. car still doesn't start up), then you may have a spark problem.

    But the starter fluid test is so easy (hey, everybody can press the button on a spray can) and cheap that it makes for the best "first test."

    Listen for the fuel pump. If you don't hear the fuel pump when you turn the key on no need to look further.

    http://www.ferrarichat.com/forum/showthread.php?t=73463 . I think the wiring might be the same as the 328. If so there is a thread from a couple months ago when my fuel pump wouldn't run. Maybe someone else can tell us if the wiring is the same as the 88 328. I posted some pics of the parts and some simple tests you can try. On my car the fuel pump is on the lower left side just behind the passenger door. Should be fairly easy to hear but you could always get someone to stick thier head under there and listen while you turn the key on. Pump should run for a few seconds then turn off. Look through the thread and related links in the thread and it should give you a pretty good idea of what's going on. Let us know what you find.

    The fuse may look fine, but have bad contacts. Did you use a jumper wire to bypass the fuse as I suggested?
