Can't Start 92 B2200

[kubes]

This thing has started every day for three years that i owned it and today it decided different, it cranks but does not fire. There has been alote of moisture and wet in the air but don't think that has much to do with it scence it has been through alote of rainy days and started fine before. The distibutor seem to be nice and dry. but other then that what should i check or test. pls and thanks. kubes

Only two things to check, Spark and fuel.
These trucks are very simple to work on.

Remove spark plug and cable on No.1 cylinder and check for spark while cranking (ground the spark plug). If you don't get spark, could be bad coil or distributor assembly. If you get spark, test fuel pump.

Remove air cleaner housing to expose the carb. Remove ignition coil power supply and grounding wires.
Remove the fuel supply hose to the carb and lay it upward.
Crank engine and see if you get fuel coming out of the fuel pump discharge hose. If there is no fuel coming out, fuel pump is shot.
Fuel pump is located on the back passenger side of the motor for carbureted. FI motors have electric fuel pumps located somewhere under the truck.

Cool i try those trouble shooting ideas first thing saturday and post my results, Thanks

i pulled the the #1 plug and had it ground out while i had someone else crank it, no spark. i looked and two places for a coil thinking that would be the easier of the two to look into first, but am having a hard time finding an after market one, should have it tommorow, What are the chances that it is the coil? could it be as easy as a cap and rotor? those were sold out at the automotive place i was at aswell.'

If there was no spark on the no.1 spark plug, it could be the distributor, cap and rotor and coil.
Now to eliminate which one is bad, try these.
1. try the output from the coil. pull the plug wire from the center of distributor cap and insert the spark plug and ground the spark plug. crank and test for spark. if you get spark, your coil and distributor are good, and your rotor could be out of time. Check rotor timing.
2. if no.1 fails, your distributor assembly and coil could be bad. you need to test the coil. with the same set up. disconnect the negative wires on the coil. get a jumper wire and hook one end to the coil negative terminal and ground the other end to chassis with iginition ON. now, remove the grounded end of jumper and check for spark. if no spark, check resistance on coil to confirm a bad coil. if you get spark, distributor assembly is bad.

sorry i was on the road, i will be going thru the test you have told me to do but get this, i put a new coil in, a new cap and rotor, and she still does not start, and i put a new plug wire from the coil to the distributor as well. i tested with my test light to make sure i had power to the coil when the ignition was on and one of the two wires to the coil showed power is that good? the other did not, second of all i had my buddy put his finger on the out put of the coil wire and i cranked it over, he did not get shocked does this mean there is no power comming from the coil.

some one said somthing about a crank positioning sensor or cam sensor, might be the problem, is there any of these type sensor on my truck that could be not allowing my coil to fire?
