I have the same year truck as you do. Replaced engine last year and now this same exact thing is going on. I've talked to several people with the same problem. They have said to check the distributor and see if the bushing is worn out. This will cause the reluctor wheel to hit or miss the CAM sensor. Causing the sensor not to get the correct reading. So I took my truck to a very reputable garage, sure enough 12% difference between the CAM and CRANK sensors. Now if the distributor needs a new bushing or replaced a Automotive shop has to "relearn" the the system. After you replace either one. So that they are working together.

The vortec 5.0l and the 5.7l have intake gasket problems.When the gaskets leak they cause symtoms like no power,poping from the TBI,skipping, miss firing or not firing in one or more cylinders.Its not getting the air/fuel mixture from the injectors and intake it should due to the loss of intake vacuum through the bad gaskets.Check that out and see if thats your problem,usually you'll have oil on the intake and the intake bolts will not be as tight as they should be..Hope this helps you out.

How to fix p1345 obd code on 97 chevy 1500 5.7 Lt.

P1345 is "Crankshaft position sensor / Camshaft position sensor correlation"

Code P1345 determines if the distributor is installed incorrectly, or if a mechanical malfunction is present in the engine. The light will trigger when the engine is running and the camshaft sensor reference pulse is not detected at a correct relative position with the crankshaft pulse. Most likely causes for this Chevy check engine light code include a faulty crankshaft position sensor, a wiring concern or an improperly installed distributor. A quick check on the crankshaft sensor is to monitor the RPM value with a scan tool while revving up the engine. If the reading is close to twice the expected RPM, then the sensor is likely faulty. There are other less likely concerns possible, such as base engine or computer related issues, but these involve more in depth testing. I hope this information is useful.
