May take some sleuthing.

As in sleuthing if this was mine I might tap into the power leads to the pump and run them up into the cab so I could monitor the voltage to the pump. This is entry level electrical work so most technicians can do this. I take it you want to avoid just replacing the pump and hoping.

Another thing that I think is worth doing is replacing the fuel filter. I've lost count over the years where it just fixes odd problems like that. Here that's a few bucks and usually easy to change out. Why do I do this? An old mechanic saying "What's the cheapest thing it could possibly be?"

Are you saying that the car won't re-start?

In reply to: How to fix fuel pump problem

That may or may not be caused by a fuel pump. I can't speak for the one you have but some pumps won't restart if it needs to work against back pressure. This is by design so as to protect the pump motor. I know home AC pumps work that way and will delay re-starting until the pressure bleeds off. Sometimes one can hear a brief whirring noise when turning the key but prior to engaging the solenoid. This may be the fuel pump pressurizing the system. If you've stopped only briefly, I could imagine that there's still too much pressure in the fuel system for the pump to run until you're actually consuming fuel. If it's not causing you a problem, I'd not worry too much about it.

Fuel pump?

In reply to: How to fix fuel pump problem

Are you NOT hearing the pump run when restarting? I've used a funnel in the fuel neck to amplify the pump noise while having someone turn the ignition "ON". The pump, normally, will only run for a few seconds. A cold start working fine suggests to me that it's not a lack of fuel. The fuel pump, of course, is inside the fuel tank. The fuel in the tank keeps the pump cool. Too low of a fuel level can allow the pump to overheat. A pressure reading with KOEO would be helpful to know. (when it won't start, of course. Happy ) Another trick is to smack the tank with a rubber mallet while someone is trying to start. This would 'shock' the pump, and possibly, start. If that is the case, replace the pump.
