I just got a 1990 gst and drove it three hours on the way home. when i came off 285 onto 85 north, the car died out and i restarted it while doing like 55. At this point, i just try to stay in the gas and keep revs up. then, on 85 i got off on the sugarloaf exit to go home, and she died again and this time, wouldnt restart. so i got it towed home. where it sat until the tow truck arrived, there was a small oil circle (about 3" diameter) and my girl said before i exited, she saw blueish smoke...??. anyway, i get it home, and my buddy says he thinks its the fuel pump because its making a weird ass surging sound and he said it the fuel pump clicking.... i went outside to check it out today, and my battery was dead (i left interior light on last night while cleaning it). So...Does anyone know if there is something that might sound liek this and be a easy fix or is it something bad. It never ran hot and held oil pressure the entire way home so i dont think internals are damaged but i cant figure out where the oil came from. Im going to put the battery on charge for a bit but if anyone has any ideas where to start, please, any help is appreciated and sorry for the long reading. Thanks in advance.
