My 1981 Fiat Spider starts and runs for a couple of seconds then shuts off, can anyone help me diagnosis and fix this problem?

How is the fuel pump? Is it showing good steady pressure?

Yes the pump is good, I just put in a new one. And that didn't fix the problem.

I'm in the same boat...runs for a few seconds & stops...Fuel system has been completely restored.I just replaced the positive battery cable which restored power to my lights & blinkers etc, I'm at a loss.

Hi, I had the same issues and it was getting worst. My mechanic looked and checked everything on ignition / Electrical parts and to fix it: - All Ground in your tuck have to be solid - Catalytic Convector needed to be changed -A-

Check the connection and wiring to the coolant sensor in the top radiator tank. The wire had broken (all but a few strands) on my Spider 2000 and it ran fine upon start-up but would die when warm. The computer did not receive a signal that the engine was warm and was making the fuel mixture too rich for a warm engine.

But the radiator fan turns on. On mine. Is there a possiblity the computer might be out

Did you ever figure out what the problem is I am having same problem . I have tried almost everything

Had a simular problem on my 78. When it dies does all of the gauges die. Mine did and after months of chasing the problem, I replaced the ignition switch. Solved the problem

My gauges all turn off at the same time , its like the power is killed immediately.
