92 gmc sierra with throttle body problems starting one time it will start right away then I can drive across town and it will crank till the battery is dead, the truck has been parked for about a year but I am on the fourth tank of gas since I got it back on the road I changed the ignition module and when turning over I checked and it does have spark. Before I parked it I replaced the fuel pump and filter.
