Update. Put the new relay in and fuel pump seemed to work great. Hopefully that fixed that issue.
Took the carb off and found out that the roll pin came out of the cam and was not lifting the lifter. Therefore as a result it was not squirting fuel. Put a new roll pin in there and it fixed that issue. Then got the car running and pretty well. Adjusted the timing and everything seemed to be running good but then....
Went to turn the car around on the lift so the back was facing the garage door so we could run the car for a while to dial in the carbs. While driving up, the external oil cooler drain bolt hit the lift and cracked the housing and oil started to leak everywhere. Honestly my grandpa had all of the external oil cooler lines run pretty poorly so I will now have to redo all of them. Below is a pic.
Now I Need Help! 1) I need to know where does the oil temp sender wire plugs into under the battery? I looked everywhere and couldn't find it. The wiring is not stock so I'm sure that doesn't help
2) At idle the volts is just under 12 and then when you hit the brakes or turn signal it drops to under 10. Is this normal? If not, what should it be and how do I tell if the alternator is bad or something else? If something else, where to start?
