1993 firing problem. I need HELP

I have a 1993 spd. 4.0 that will turn over but not start. for a while I
was able to bump the selenoid and provided there was fire from the plug
wire to the coil pack, it would crank up. When that no longer worked and
there was no fire to the coil,I replaced the coil pack. I cranked up once.
The second time I tried to take off in , it acted the same way. Turn over
but not fire up. Plenty of gas, New fuel pump and filter, new plugs and
wires, timing chain okay just no fire. Does anyone know whats going on
with this thing? I'm truely beginning to believe my truck is possessed!!!
Help !!!

Just off the top of my head a couple of things that could cause it to not
fire would be a bad battery, bad battery cable(s), or a bad crankshaft
position sensor. Or possibly a bad wire somewhere (rats?) . Sometimes the
battery will have enough juice to turn the engine but (I guess) the computer
will just say no to sparks if the battery voltage is too low. Some people
have argued with me on this but it has happened to me. Jump starting may
or may not help as long as the bad battery is still in there and connected.
These engines are also notorious for bad battery cables, especially the
positive cable. I don't remember the exact symptoms of a bad ignition
switch but I would not rule that out either.

Hmmm I never thought about a low battery. When I first started having this
trouble, I could easily start the truck by jumping the selenoid with a
screw driver. It worked for a short time, the got progressively harder.
When I put on the new coil pack, I was back to being able to start it
easily jumping the selenoid. What about the ignition control module or the
SPOUT connector? I dont know much about these two and dont want to disturb
them until Im more sure what their functions are.

try getting your ecm checked (computer) could have a fault in the
ignition processor, it sends a faint signal to your coil pack and tells
it when to turn off and on im almost 100% positive this is the problem.
location is under passenger side of dash located on kick panel. part is
only like 10 bucks at the junkyard.

If you didn't yet check the crankshaft position sensor I'm not certain where
it is on your engine but on the '97 4.0 it's in the front, underneath,
pointing at the crankshaft pulley. It has two wires. Possible problems
might be a damaged wire, bad sensor, or dirty connection. If the computer
doesn't know what the crankshaft position is it won't spark. The cheapest,
easiest thing to do would be to check it for damage and clean the
connection.

Other than that I'd say it's time to get your error codes read. The codes
should point to whatever is at fault. Many auto parts stores will read the
codes for free so they can sell you parts.
