Do you know if it is missing spark or fuel? Does it have a security light on?
Which pink wire? When is it ground?
The coil should have 2 pink wires. Both should be power the white wire is trigger. SO when testing the key should be on and engine off.
here is a diagram
key off it will be. Thats how it shuts it off
Only be concerned with what it has key on. You say it has weak spark? How did you determine that?
The pink wire should be battery voltage
That should be sufficient. Did the distributor come out of truck or engine?
Is it possible it is 180 degrees off? Which valve was next to open when you rolled over?
So when you roll the engine with distributor pointing to 1 which valve is next to open?
When you are at top dead center and you place the distributor pointing at 1 you should always roll the engine and verify which valve is next to open. It should be exhaust. Both valves will be closed when piston is up both times. So it is possible you are 180 off
it is either remove valve cover or pull distributor and turn it 180
3 days until it times out. you can reply after that
I am pretty confident that you will find this fixes it. as long as wires are hooked properly.
I will check in morning. I will be answering questions for another hour or 2
shoot I was pretty confident that was the problem. Have you tried spraying carb clean and see if it runs?
Did the distributor come out of truck then> Have you tried swapping with one that came out of engine?
Are you confident that it is pointed to the right plug? Also are you sure wires are all hooked up?
Is this what your distributor look like?
Why the big gap. do you have correct rotor?
no way that should be a 1/4 inch
If you attach a test light to ground and crank the engine with the wire off coil and hold the test light to coil how far will spark jump? Make sure you have good ground
Is the coil mounted? DO you have another coil?
what is the voltage at the pink wire? again are you confident that all of the wires are hooked up properly? Specifically at the starter?
What is the voltage of the pink wire? The ground is at least as important also.
Which computer did you use?
OK. So lets get back to basics
What engine did truck have in it? same or V6?
Which computer is in truck now? If engine size is the same make sure you use computer that belongs to truck
I am attaching a theft learn procedure I suspect you have it in theft mode
I do not have a lot of time tonight. I would suggest doing a fuel pressure check. check fuel volume as well.
