Late last fall, the sending unit in my son's Fiero stopped working so we purchased a new one. After putting back in the tank, it would not start, then we noticed the Fuel pulseabor was a little loose and warn, so we replaced that with a rubber hose and it fired right up. Had some more things to work on so we left it up on the jack stands for a couple weeks.

When we put it down on the ground it would not start up again, Winter came and we just stored it, tried starting up last week and again fail, pulled thank, and the rubber hose since it was soaking in gas swelled and frayed and would explain the 10 psi fuel pressure or so we thought, we replaced that hose with a new fuel pulseator, thought that would do the trick and still it won't start, and still is only getting 10-15 psi of fuel pressure. Car was running great prior to changing the sending unit.

Some other notes, the Fuel pump is working, we've changed the spark plugs, distributor cap, wires, it's getting air. The only thing it's not getting is enough fuel pressure.

Any ideas?
