I have a '97 chevy tahoe. the engine cranks, but won't start. checked trouble codes & got cycliner misfire, O2 sensor, & catalytic converter codes. i've replaced plugs & wires. still won't...


first, check all the fuses
did you check to see if there's spark at spark plugs?
did you check the fuel pressure? you need to do that to isolate fuel and ignition system.
if there is no fuel then check for fuel pump operation
if there is no spark then check the ignition system (coil, module and wirings)
if you don't have either one then the problem is in the computer system such as crank sensor, and computer itself

Fuel pressure and spark


usually with a special gauge-n to chec for ignition take plug out with wire attached and turn car over-a little but the best thing is to get a haynes manual at a discount place

Isuzu Hombre pickup, 2.2L Vortec, Won't Start.


You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

96 dodge caravan 3.0 has p300 and p306 codes,


A P0306 code means that the the ECM has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

A code P0306 may mean that one or more of the following has happened:

Faulty spark plug or wire, Faulty coil (pack), Faulty fuel injector, Burned exhaust Valve, Poor compression, and Defective computer. 

Check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the Caravan, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). The number six cylinder is the one towards the radiator and drivers side. If you are going to change all the plugs and wire keep me posted, be glad to help. Good luck and hope this helps, P0300 just means multi miss fire.
