94 silverado won't start, please help

[tleeburks]

hopefully this is the correct message board. ok here goes. i have a 94 silverado extended v8 i believe with a 5.7 engine. it won't start. in the past it started kinda of sluggish, but did start and ran fine. recently, a couple nights ago, i didn't start. i went back to get it in the morning and it turned over a bit but didn't start, its cold out here in the midwest. i bought a battery at walmart, still didn't start. took battery back, bought starter, had mine tested first, no fire. anyway. just installed starter, just clicks. no turn over at all. tried to jump it, nothing. anything else before i call the mechanic and he makes money off of me. ha ha. seriously, please help. thanks

There are a few tests I need you to perform, and a few things to check. First, Make sure the engine is not locked up by turning it by hand. If you cannot turn it with a wrench, take off the serpentine belt and then try to turn by hand. If the engine will turn with the belt rermoved, then some acessory is locked up. If the engine will turn with the belt on then continue reading, if the engine just won't turn then the engine may have an internal problem. Check for any corrosion at both Battery cable ends that are connected to the battery. Peel off the plastic shroud with a small screwdriver and inspect, clean to a shiny new look and coat with vaseline petroleum jelly and reinstall both. Get a new bolt for it if needed, they are available. Take a voltmeter, and connect one end to the engine block, and then to the negative terminal of the battery, crank the starter and read the volts. there shouldn't be more than 0.5 volts reading on the meter. if there is, then check the connection at the engine end of the cable. Clean up & coat with pet. jelly as before, retest. If there is still more than 0.5 volts, then test the resistance of the cable, end to end. This is measured in OHMS. There should be almost no resistance in the cable. If there is a lot then replace the cable, there may be a beak inside the insulation. Then connect the meter to the positive terminal of the battery and then to the positive lug of the starter. Crank the engine and read the volts. No more than 0.5 Volts. If there is more, then check the starter end for corrosion, clean & coat as before. Retest, and check volts, and check resistance same as before. After all this, repost with results.

wink here, try the ignition modual. itis located under the distributer cap black with a couple of wires front and rear. replace it and should start.
