How is the battery? ... Is it Fully charged?
Hate to mention the obvious But.... The problem with using a shortcut, like jumping the solenoid with a screwdriver is okay to get you going again... IF you follow up with repairing the actual problem...
If you fail to do that, (and I've done similar things) ... you can end up with multiple problems each interacting with the other, making the ultimate repair very frustrating...
So I would start with a very good, well charged battery, & good clean cable connections at each end of all the cables... then I would find where the voltage drop is in the starter system...
Starters them selves are fairly robust an rarely fail... but they can have a problem.... I would wring out everything else First... :smile:KennyV
