Car won't start. Lights and radio flickered while driving for a couple days then car wouldnt start. New alt and good battery. Tried to jump and lights come on but radio doesnt. Theres no starter click

Check the fusible link wire first.

Then check battery voltage.

Then check the cleanliness and contact surfaces and the tightness of the battery cables. Do the same on the starter solenoid connections/wires.

Reset (replace) computer box

The fact that all your electrics disappeared including all dashboard lights indicates a faulty battery/connection.

Check the battery terminals for cleanliness and tightness. Check the black earth lead for cleanliness and tightness where it connects to the engine block/bodywork. Try adding an extra black battery lead - connect it to a suitable point on the engine or bodywork

Need to troubleshoot a 2007 model Venture - will not turn over to start; battery good, relays and fuses good, how do I begin to troubleshoot ? Need a wiring diagram. I have an OBD2 code reader-will this do...

Check your battery terminals for cleanliness and tightness, then check your dash for security lights when you turn your key to the on position, see if any lights stay on. You may have a security system issue. The OBD2 code reader can come in handy to see if you have any stored or pending codes, that maybe causing some of your issues. If you do have codes this can start you off in the right direction to start looking.

How can I check for a fuel leak in the passager side tank? And how many gallon's of gas dose eack tank hold? 1986 GMC K1500 4X4

Each tank hold about 17gal. For the leak, first a thorough visual inspection. If no leak is found remove the plastic shield. And give it one more good lookin over. If STILL no leak is found, you can purchase a UV dye additive that will highlight the point of puncture under a UV light.
