Fuel Pump

[hosmerb]

I've been going through an '86 944 that was parked for about 6 years. The car turns over and has good compression so I am encouraged but my latest challenge is that I'm not getting any fuel to the rail.

I drained the tank (yuck), ran through some MEK, cleaned the pickup screen, added fresh fuel, made my garage smell like varnish and put in a new fuel filter. I removed the fuel line that goes to the regulator farthest forward on the rail, jumped the DMR(?) relay and can hear the pump turn on but get no gas.

The gas that came out of the tank was crap and obviously the stuff sitting in the pump was no better so my thinking is that either the pump is bad or the check valve in front of the pump is stuck. I made a fixture out of an old gas cap and put some compressed air into the gas tank (which seemed like a bad idea at the time but I did it anyway) and no fuel or air came out of the line.

What should a fuel pump sound like? This was definitely a hum and not a whir; and it never changed pitch, just a steady hum. Is there a shot that the check valve or pump is just stuck?

I ask these silly questions because I, like most of you, am beholden to my kids, wife and a pesky chore jar that I swear is reproducing asexually. My availability to work on this thing is limited. If I have a shot at saving a few hunge by cleaning out the check valve, I'm down for it. Otherwise, somebody slap me to my senses and I'll buy a pump.

Thanks in advance for your replies,

Path of least resistance would be replacing the pump. I doubt the check valve would cause a zero fuel situation.

Also, I wouldn't get too excited about starting the car until you have changed the timing belt. You are headed down a road that has cost many valves.

Fuel pump is gummed up, change it....and do like Rasta said, change the cam and balance shaft belts before you start the car.
