After checking fuses, relays and fuel pressure testing, it seems the fuel pump gave up the ghost. There is no "fuel pump" noise when I turn on the key, but the car will start and run for a few seconds when I spray engine start fluid in the carb. There is oil pressure on the gauge when the engine starts. So, never having replaced a fuel pump in an 88 GT, 2.8 L., I am seeking any advice or recommendations on how to go about this. Also, what pump should I replace it with so I don't have any issues with it being reliable and compatible with all related systems and components? The local parts store has an A/C Delco replacement, but I believe there are other pumps that may work just as well or better. Thanks for your input.
I have an Airtex fuel pump from auto zone that I bought and installed back in Jan 2012 and have had no problems with it and it is on a daily driver Fiero. But it seems now a days that with any brand you will either get a good or bad one, seems like its the luck of the draw, as I have read here before replacing mine on what brand to get like you are, so I just went with whatever they had at autozone.
Did you apply 12v in the ALDL connection? There is a pin there where you can put 12volts directly to the pump. If that doesn't work, then you have a wiring issue, or a bad pump. (port G)
Thank you S-toon and Jackispyder. I read both articles and they are a great help. One other question (s). What is a "Pulsator", where is it, and does it have to be replaced along with the fuel pump? Thanks.
I'm not great with technical jargon but the pulsator is on the assembly after the pump. It controls the fuel pressure by maintaining it not have to spike the pressure from the pump every time. If you're there you should either replace it or typically a piece of hose is included in the pump kit so you can bypass it.
Thanks for the responses. The A/C Delco seems like a safe bet. As to the Pulsator, do I replace the it or bypass it when I change the fuel pump? What bad things can happen if the Pulsator is bypassed?
The AC Delco pump comes with a short piece of tubbing and 2 hose clamps to replace the pulsator. If the Pulsator looks good I will re-install it. Also replace the strainer at the same time.
Take a look at the DW 200 pump and has sufficient flow (255 lph) to run a stock 3800 SC engine. It has a three year no fault warranty and can be purchased for about $96 (including an installation kit).
