    no I did not get any backfiring, and the timing was right, I did what you said and check everything, my timing is right,I had already did what you said, but it still won't start.

Did you sync up the engine properly when you reinstalled the timing belt/chain? It is possible to be on the marks and be 180 degrees off. Align the timing mark on the crankshaft then check the rotor position.If it doesn't point to number one wire terminal position roll the engine over until the crank lines up to the timing mark again. The distributer needs to be pointing the wire terminal that goes to number cylinder.Any other position is unacceptable and you can't simply turn the distributer to number one either You need to retime the crankshaft to the camshft making sure that the distrubitor points to number one and both valves for number one cylinder are completely closed.

    Do you get any backfiring? When you checked the valve timing was it off?

  • Howard Lester Nov 30, 2008

    The fact that the exhaust gets hot indicates there must be some combusion. That is why I wanted to know if it backfired. Loosen your lash on the rockers a few turns and see if it starts. It won't hurt things if they clatter a bit.

  • Howard Lester Nov 30, 2008

    I feel I need to mention that if it starts reset your valve lash.

Whats the proplem ifthe spark plug is wet with petrol

If the plug is wet with fuel, it is an indication that the plug is not firing properly. Possible causes? Distributor cap, rotor, points/inductive pickup, spark plug wire or the spark plug itself. If you or a friend, relative, etc. has or has access to an inductive pickup timing light, connect the light to a power source and the inductive pickup to the plug wire of the "wet" spark plug. Start the engine and observe if the flash from the timing light is relatively constant in its frequency or is it erratic and sporadic. If the latter is true, check the distributor cap, rotor, distributor points/inductive pickup and plug wire. If the former is true, remove the spark plug and check the compression against other cylinders. If compression is good, replace the spark plug with a new one. If compression is lower than others, the air/fuel mixture in that cylinder is not being compressed engough for combustion, leaving the spark plug "wet". To learn the cause, put a teaspoon of motor oil in the spark plug hole, and recheck compression. If it doesn't increase, you probably have a valve or head gasket problem. If it does rise, you probably have a piston ring problem . Good luck

I have a 89 1500 with a 350 5.7l and i poot a new 350 5.7l out of a 94 and now flames come out of inj when you start it

You either have the firing order wrong or the timing is not set right. You get fire out of the intake when a spark plug fires when an intake valve is still open. Order is 18436572 cylinders are 1357 front to back on drivers side, 2468 on passenger side. Turn the engine so the mark on the crank points to "0" on the timing scale. Set the distributor so the rotor points towards the front of the engine (not exactly but not at the firewall) If when at "0" it points to fw, turn one more time. Set wires on cap with #1 aligned with the rotor, then all others in order clockwise.
Only other possibility is that you have the valves adjusted too tight, have a bad cap or rotor or the replacement engine has a burned valve (doubt it).

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.

you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.
