Timing is not adjustable. You do however need to turn the distributor to set the cam/crank correlation to keep the check engine light off. Although you need to hook it to a scanner to be able to set this.

I have a 96 chevy tahoe 5.7 vortec and it had a small knock in it so we put in a new crankshaft,main bearings,rod bearings,timing chain,timing cover and all seals and gaskets now the truck misses on number...


Oh man that's a tough one. It almost sounds like a bad head, however there is an electronic spark control mounted to the firewall, that could possibly be doing it. If it is fuel injected, check your injectors. Something else to check would be the fuel pressure regulator. I'll have to think more on it, because you have replaced so much. Have you checked for trouble codes? The throttle position sensor can cause some of your symptoms. Hope this helps, but I think you might have a faulty esc control (electronic spark control)

I have a 98 chevy z71 5.7 350 vortec, i have a p1345 code that stays on i clear it and as i restart the truck it comes back on, the truck runs great and has a small delay when starrted.. what can/do i need...


1345 is cam and crank sensor correlation its mainly the cam sensor going out, also the delay start that also trigger a camsensor code they call it excessive crank time check the fuel pressure that is capable of setting a cam code (1345) If fuel pressure is good (55-60 psi) expect to replace the camsensor you might as well do the crank sensor heres a nightmare on this code it can set if the distributor is off one tooth and yes these distributor have high failure rate

P0340 - Cam Timing

SYMPTOMS/CONDITIONS
of a mistimed camshaft system (all must apply):
  1. Camshafts have previously been removed from the engine.
  2. Engine runs rough.
  3. Vehicle sets P0340 (camshaft sensor code).
  4. Camshaft sensor has been checked with a known, properly operating camshaft sensor.

CORRECT:
The diagram in the manuals should show the timing marks on both cam gears to be on the blue timing chain links.

1999 chevy suburban 5.7 L. vortec. Can a bad camshaft sensor cause a no start? rebuilt engine, fuel pressure 60 LBS.,spark at all the plugs, compression 140 lbs, timing is dead on.


i do believe it will not start with out it if you can hook up a scan tool to it crank the engine and look at rpms while cranking should read about two hundred forty rpms thats what fires the injectors the cam sensor tells the computer what cylinder is ready to fire next also scanner will set the cam timming.

I take it,you replaced the crankshaft sensor,now,the cam sensor(pick up coil)is most likely the problem,it is either not lining up,or,there is wear in the distributor.The crankshaft sensor is not aligning with the cam sensor(pick up coil).

pull the radiator and ac condensor core out, remove the valve covers, rocker arms and push rods, remove the intake manifold, remove the water pump and crank balancer and then the timing chain cover, remove the timing chain, using a long bolt carefully remove the camshaft.
