Re: Cams.

If you revealed a few details on the engine you are thinking of putting them in you might get a more helpful answer. Absent any info we almost always assume you are asking about our engines. In my 1981 Fuel Injected 2L Spider in stock condition I would not expect any benefit from non-stock cams.

Re: intermittent starting problem

Dave, Clean and tight electrical connections are as important to electrical systems as lubricant is to mechanical systems. On a related note I recently experienced a locking solenoid failure my two-year old Grand Caravan. As I disassembled the driver's door innards I was impressed by the apparent at...

Re: intermittent starting problem

The classic intermittent symptom of the Delco HEI ignition module used in the Marelli electronic ignition is working when first started and then failing after running a bit and heating up, particularly when stuck in slow moving traffic. High underhood temps, dried out heat sink grease on the back of...

Re: intermittent starting problem

The only way to diagnose an intermittent failure quickly is to test when the failure is happening. The next time it fails to start rule out the ignition side by confirming that you have a fat spark when you crank. Knowing that the problem is on the fuel side gives you some focus. Diagnosis by part r...

Re: Engine Dies

Do the old diagnostic drill, test for fuel and spark. Open the air cleaner, work the throttle linkage and look for a squirt of fuel into the throat from the accelerator pump. Pull a spark plug lead and rest it next to the hood latch and look for a spark as you crank.

Re: WTH Spider Rear Racing Suspension!

The double trailing arm mod was popularized on the West Coast by Dave Voss and others. A second set of lower arms is mounted on the inside of the stock arms by doubling the length of the mounting bolts and cantilevering the additional arm on those longer bolts off the inside mounting brackets. I ran...

Re: To weld or "glass"

At some point in the mid-70's Pininfarina modified the passenger floor to accommodate both the re-routing of the exhaust to the passenger side and the provision of a cat under the passenger floor. However, many 49-state Spiders continued to be sold without cats for several years. If you have a floor...

Re: brake upgrade complete, the saga

Mike, Your saga reinforces some things I've learned over the years. The first is that I am not an automotive engineer. Particularly on parts that affect the safety of the vehicle I need to have a compelling reason to depart from the original design or at least the benefit of the experience of others...

Re: EDIS Trigger Wheel.

Ralph,

Here are four pictures provided by Jason Miller in 2007. This is the 36 tooth pulley and sensor mount that work with the 1995 Ford Electronic Distributorless Ignition System control box and sensor.

Re: 1975 124 Spider 8 Relays?

In the library's general area are the Fiat NA service letters. In 1976 they issued a letter with the location of fuses and relays shown in diagrams of each model then sold for the model years 1974-1976. I think those diagrams are the most definitive ones available. https://www.mirafiori.com/forum/fi...
