Need a better serial number
Only way it may have a MEFI -2 is maybe if its a L29 model
Fouled plugs one side and white on the other, double check all the plugs
MY thought is there might be a small intake leak and had just enough to get a small amount into a cylinder. If that's the case, the PB sitting long enough should free it up over time
Start with basics
Is your battery fully charged?
What happens when the starter engages?
Do the battery cables heat up?
Can you turn the motor with plugs out by the belt?
Without knowing which 3L it is (ah no serial number)
If gauge is accurate its your running hot, not over heating but unless its closed cooled it's running hot
Need a better gauge, the numbers are high (150 for new motor) but difference between cylinders is good
With 2 and 3 being tan (good color), 1 and 4 is from oil. If it was fuel all would be black
I want to know if the voltage drops at the starter while the motor is cranking. If it drops below 10V the starter does not have enough to turn the motor over.
Doing the same test at the Bat will help but need to know at the starter
The ACR should connect both Positive terminals on each Bat...
Can look good but be corroded under connections
The ACR is not the issue
Those auto type connections should not be used. Connect the cables direct to the studs next to them and use nuts
Did you get a meter reading?
