1986 DL Fuel Pump?
My daughter (proud owner of a 1986 DL) called and described the following problem. The car will start, run for 3-4 seconds, then die. Before I diagnose over the phone with her, I need some advice. I suspect a fuel pump, but which one? Can anyone help? Many thanks in advance.

I am by no means a expert around here or even close but i have had some "fuel pump" problems lately.
I would check the fuel pump relay or fuses. Might be injector related or the pumps. I dont think the car would start at all if the external pump was out. Heck the other day i forgot to plug my in tank pump in and drove around for 10 minutes pretty solid, so that just goes to show you. do the 86's have a AMM? I know i dont but maybe that might be worth a look. Has the fuel filter been changed recently? She might also have a vacuum leak, im just guessing here.

Thanks qstyle.
I do not know what an AMM is. My daughter lives out of state so I will travel there this week. Just trying to get my "ducks in a row" before I get there. I will get a fuel filter for sure, but the pumps take longer to get so I wanted to get an idea before hand. I appreciate the input.
