Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
is this a 5.3 engine in this vehicle ?
can you get it to act up to do a few quick tests ?
do you have a multi meter on hand or a test light ?
we need to do a few quick tests to see what is going on
when it is acting up with your fingers on the starter relay do you feel the relay click with your fingers ?
if you do NOT feel it click when holding the key to the crank position does the fuse called CRANK in the under hood fuse box show 12 volts when holding the key to crank ?
let me know
