Have you checked for spark at the plugs? Are you certain that the timing chain and tensioner were installed properly? Camshaft position sensor and crankshaft position sensor are OK? Without the right signal, nothing happens. Have you checked the coil packs, plug wires, and spark plugs? If there is no spark while cranking, you'll have to figure out why, and a shop manual is about the only way to go to do that. If you have spark, then you need to check for fuel at the injectors and the proper injector signal. Have you checked for fuel pressure at the rail? Does the fuel pump run? Is the fuel filter plugged?
It could also be a wiring problem somewhere in the electrical harness. If the right wire or wires are broken or corroded, then it could easily keep the engine from running. Even a loose or broken connector or a bent connector pin can cause all sorts of headaches.

SOURCE: no spark

Here are a couple of ideas. However, I think you've already covered most of them.

1. Remove the distributor cap and crank the car. If the rotor turns you're ok. If it doesn't turn then that's you're problem and you will probably need to change a timing belt/chain. (already done this)
2. Check the spark from the ignition coil by pulling the coil wire from the center of the distributor. Use an alligator clip to attach a short wire to the coil wire contact. Bare the other end of this short wire and set it up so it's sitting very close to the engine block. Turn off the lights and try to start the car. You should see a spark jump from this wire to the block. If you don't see a spark it's likely your ignition module (already changed) or ignition coil (could this be it?)is bad.
3. If you have a spark maybe it's not getting to the plugs. You may need to replace the distributor cap and rotor. (already done this) You can test if the plugs are sparking by pulling one, re-attaching the spark plug wire and seeing if you get a spark when you try to start the engine in the dark. Please note, the metal threads of the spark plug need to be shorted to the engine block to complete the circuit during this test.

Looks like ignition current is not being available to fire the fuel/air injected mixture from the plugs. Remove the cable tip which connects TO any plug. Hold the cable tip to any metal part of the engine block or any part of the body where the metal is exposed(not painted). Ask a friend to turn the ignition for starting the engine(vehicle). If the cable tip produces sparks, then the induction coil is OK, but since you have stated that clicking sound is heard which is actually the relay's which tries to get the induction coil to generate high current required for producing the spark to ignite the fuel & air mixture in each cylinder, thus starting the combustion required to turn the engine & subsequently power. So check the induction, belt tightness and finally the "Distributor"in the sequence as stated and you will be able to diagose which one of the above are malfunctioning............sodeep

SOURCE: how do I replace the starter on my 1993 chevy?

Disconnect the negative cable from the battery..
Under the front end - find the starter near where the trani connects to the motor and the really big gear (flywheel) is..
Undo 2 bolts to remove the starter.. take the wires off and be sure to put the wires on the starter the same way..
Connect the wires to the new starter and put the starter in with the to bolts.. The starter will only go in one way so you cant mess up how it goes in..

Good luck !

check the valve timing after replacing the chain. check that you connected the ignition module to the coil. Check ignition timing as you may be out 180 degrees on the timing.

My gmc 4.3 stalls when warm and wont start without ether. then it runs fine


I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

If you have a healthy spark (a blue snapping spark), it would not be a problem in the ignition system or the module. An orange, weak, or intermittent spark could point to trouble in the ignition.
I would check the timing on it, maybe it is a timing chain problem. It should have fired and ran a bit with the starter fluid. The fact that it didn't, even with a good spark, well, probably needs a little shop time investigating. Jumped timing from a worn chain? Low compression in one or more cylinders? A couple of things you need to consider.
Good luck.

You must properly diagnose your ignition system to find the cause of the "no-spark". There are several steps involved depending on where the problem is. It could be anything from a bad distributor cap to a failed ignition control module.

Replace the distributor, coil, and ignition module all at the same time. With HEI ignition systems generally when any of those 3 parts fail the other 2 are damaged in the process.

98 Chevy Suburban, engine turns over, will not start


It is possible for the vehicle to run perfectly fine before turning the engine off. I have seen it happen and it took me quite a while to figure it out. I would never have thought it was the timing chain until I tried to move the distributor and it kind of started. Thats when I figured out that it was the timing chain. If your vehicle has a distributor, mark the position that its in now and then loosen the bolt holding it down and turn the distributor either way and see if it will start or want to start better. Or you can set your TDC on cylinder #1 and check where the position of the rotor is under the cap. theses procedures are a little easier than taking the timing cover off and checking it that way.
