I have a 94 chevy lumina van with the 3800. New battery, starter, solenoid, cables, crank sensor, throttle sensor, altenator, fuse link from the alt to the battery, and so much more. The problem now is that every now and then it wont do anything. I have lights, radio and power but no crank, no fire at all. All the wires and grounds are good. The only thing I have but havent replaced is the ignition module. However, I thought if that was the problem it wouldnt be starting at all? Any help in this matter would be greatly appreciated. Thank you. My name is trish by the way.

Ok, changed ignition module, rewired solenoid because fuse link bad-again. Changing the ignition module still did nothing. All I get now when I turn key over is one click from the computer, nothing else. No crank, no fire, nothing? Took starter off yesterday, tested good too. Please help. There are 6 wires down at the solenoid. Not sure why I have so many, my book says I should have 4. What does this mean? And I cant find any other help online to why there are 6 wires down there. Im about to change the ignition switch just to see. Process of elimination sucks!

It could be an intermittent. See if power is getting to the starter solenoid. Check the ignition-related relays.
Is there an alarm with an ignition kill function?
The ignition switch could also be the issue.
Check the starter solenoid.

I apologize for how long it took to get back to you. Our system was down and new questions and replies weren't showing up.

Power is getting to the solenoid. Starter relay is in the starter yes there is an alarm system but it has not been tampered. I also was assuming ignition switch however, when I tore the dash apart some dumb@ss welded the plate so I cant even change the ignition switch if I wanted to, which I already have it. But the column and everything under it looks brand new. Any ideas for a welded on plate to the column? Is there anything else it could be? Like I said earlier it started thurs morning for work, and then when I got out of work, nothing. All I hear is one click down at the computer (all panels are off including the one in front of the obd system is how I heard quiet click at computer.) Any ideas would be greatly appreciated. Thank you.

The click you heard was probably the micro-relay energizing the OBD system. If you have a Dremel, you can carefully cut the welds on the plate, allowing access to the ignition switch. I have included an image of the starting circuit. Download it and change the file extension to pdf. Open it with Adobe Acrobat. Turn the key to the "ON" position and apply power to the starter wire.

Do the accessories work? Wipers. Washer. Radio. Etc? If not, make sure the ignition switch is receiving power. If so, make sure the ignition switch is passing power to the starting circuit.
