    1345 shows a mis read between crankshaft and camshaft position sensor. Since you have replaced crankshaft sensor it is possible that you problem is with that cam sensor.. but could also be that the cam lobes have worn and that they may never be in spec. with the tolerances that the computer thinks it should be. need a little more info to help more... engine???

This starting issue sounds like either the ignition timing is way off, or the cam timing is, the whinning sounds like the timing chain may have been replaced with a non silent type chain (plastic cam gear teeth), maybe the onwer got this wrong when he installed it and the cam timing is off.

I have a 1998 Chevy K1500 with a 350 and it runs rough from time to time and has a mis fire on #6


Looks like you covered just about everything outside the engine.
Since it has 225k on the engine, its possible the valves are carboned up or burned to where one of the intake valves fail to close some times.
You might try a compression test or use a vac gauge when it is running rough. If the problem was not happening before you changed the plugs, you could have bought some defective ones.

My 97 tahoe only running on 6 cylinders


If compression test is good is either no spark, bad coil or wire, or no fuel, bad fuel injector. Need to clarify which is not functioning properly.

I need to know where the fuel injector is located on my 97 tahoe 5.7


The 96'-98' vortec 350 has 8 fuel injectors that are contained inside the intake manifold. the vortec uses whats called csfi which is called central sequential fuel injection it has 8 electronic fuel injectors and 8 mechanical ones these are the ones that deliver the fuel.

Tahoe 97 Fuel problems


Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.

1997 chevy tahoe upkeep


Just check the owners manual and it will give what the dealer will check at certain mileage. Usually just keep doing your oil changes and tune ups along with all the other general maintence.

Tahoe will not start new fuel pump/w/filter


BE WARNED!!! i was a GM mechanic for years, i personally found out for myself, that many if those pumps bought from parts stores auto zone, orielly's, napa, etc... have the possibility of being bad from the factory, i once worked on a 98 silverado, the customer had replaced the pump 3 times with an auto zone pump, every time the pump would either not even start the truck or it would loose pressure within a week or two. after we installed a new GM pump he no longer had an issue, sometimes its worth it to pay a little bit more and buy a pump from a dealer, plus if you buy a GM part, it comes with a 5 year 100,000 mile warranty, even if you buy it over the counter and install it yourself.
