i have a 88 datona shelby z that will not start
I have a 1988 daytona shelby z with 13000 miles on it .The fuel pump will not start running when key is in the on position, and the gas gage goes backwards. The car turns over and will fire up with either. Its been in storrage for a long time. How Can I check if it is a bad relay or bad fuel pump , or maybe a bad ground I would sure appreciate your input
