88 ford aerostar

had a problem with starting/stalling changed out ign. coil,pick-up,module,plugs,wires,cap,rotor. still having same issue, i suspect the fuel pump, but did a fuel pressure test and it was fine, but may be an intermittant issue w/ pump, will drop tank anyway, because it has aleak in it at the top. everytime i fillup the gas leaks out from the top. also could be electricalconnections are worn as well. will let u know how it came out.

is it a 4 liter? iac valve could be stuck.
