Engine dies!
I have an issue, I'm not sure I have an answer for. I went to a huge "cruise-in" this past weekend and was stuck in some very heavy traffic. Along with the engine heating up, it died on me. A twist of the key did not good. At first I thought vapor lock. But, after only about 5 minutes and increasing engine heat, it did start right back up. I now think it may be a matter of the mechanical fuel pump not supplying enough fuel, at extended idle. I have no problem with electric fuel pumps, but can't see any reason to swap, if that probably isn't the issue. Does anyone have any other ideas? It did not cough and sputter, it just stopped. Much like I had turned the key to off.

Thanks. I was beginning to think, since so many had viewed but no one responded, I was on the right track. So, did your IM have a circuit breaker built in? How did you discover the problem?

No there was no breaker, the electronic components were just overheating and shutting down. The module was external to the distributor so to verify the module was the issue I poured water on it to cool it down and the engine started right up.

Alloro, are you describing the TFI type of module and distributor combo? That type was known for failing due to overheating because it was bolted to the body of the distributor. That does not appear to be the type that PBSDADDY has on his engine.

I don't know exactly what he has, all I'm doing is giving him something to check based on one of my past experiences.

I may know where another can be located. A friend has a similar set up.
So, not one thinks it might be a fuel pump issue? That's good, I guess. I can save that much while testing the HEI anyway.

Sorry, didn't mean to sound like I was disagreeing. The module actually fits the situation better than a fuel pump. There was no sputtering or any other indicator fuel was low.

A fuel pump tends to act up more when there's less than half a tank of fuel. So if the fuel level is not a factor in recreating this issue then you can pretty much rule it out for now.

Usually fuel pump issues show up when you're under load, and it can't keep up with fuel delivery, but they can usually keep an engine idling.
