1982 Crossfire wont run without pedal pumping

[tronder]

Bought the car this spring. Has been sitting since 2007. Ran well when I picked it up, but on my way home it started to run rough after about
one hour of driving. Don`t know much about crossfire, but I have replaced the following units from a good running (donor) 82 Corvette:
Distributor
Map Sensor
Electronic control module

Cleened the Gas-tank

Replaced Fuel-filter, Sparkplugs and wires.

Just the same.

not real clear what you are asking .but i think you want to know what to look at because the car does not want run with out pumping the pedal.i would look at the fuel pressure .the pumps go out on these cars a lot .look at the spray at the throttle body .www.crossfire.homeip.net/index.php?act=idxthis is a good source for the cross-fire.

Check that fuel filter again...there may be residual crap from sitting and/or cleaning the tank that is collecting in the fuel filter.
