Injectors will only pulse when the engine is spinning. You need to test for this pulse at the injector and check the resistance of the injector itself.

The pins can carrode but if the truck is being used they shouldn't bind up. This type of truck is prone to the brake hose collapsing at the bracket crimped around it to hold it clear of the tire. The hose will collapse on the inside holding preasure on the caliper.
To check this jack the tire clear of the ground and spin it. Press and release the pedal and check the tire again if it won't spin then wait 5 min's and try again. If it spins then it the hose. The preasure drains back slowly through a bad hose.

Check the voltage at the battery, you can do it with the lights on to see if it holds under load.
DO NOT REMOVE THE CABLES WHILE THE ENGINE IS RUNNING!
This worked on older cars but ones with computers are sensitive to voltage spikes wich you will get if you remove a cable while its running.

Sounds like a cat is in the belts to me.
Seriously sounds like a loose starter, it will drop after the engine starts and the load comes off of it.
Question Answered: How do I adjust the air gap on the A/C compressor clutch ?

There is 2 bearings in the front of a compressor. When the clutch is disengaged you use the one in the clutch, when the clutch is engaged you run on a bearing in the front of the compressor. I would suspect it.

There is a seal on the oil pump where it seals to the spinning crankshaft. This seal can wear out and leak, especcily since its pressurized oil.
So yes they can leak.

Struts don't carry any weight or supply lift they just dampen the spring bounce. You do have springs on it don't you?
Question Answered: Why would an 88 town car with a 5.0 run and then die when it warms up?

The TFI ignition modual in the distributor is probably bad. It is cool by the distributor so when the engine gets hot the modual over heats. Most parts stores can test it for you but it takes a special socket to remove it.

If its behind the AC compressor its probably the oil pump mounting. If the AC bracket is tightened in the wrong order it will couse this.
