I was having problem with the starter. I changed it, but when I tried to fire up the engine the engine does not fired. Seems like the alarm is not allowing electricity to go to the spark plugs.All fuses are good.

Re: Engine is not fireing-up
If you have a car alarm, it may have a starter kill feature that diables the starter. First you'll have to disable the alarm, then check and try starting the vehicle. You can always turn the alarm back on when your finished.

Please define "fire power". Is this just the power from the battery swinging the engine, or did you check if there is a healthy spark on the plug wires? If an engine dies without warning, the chances are very good it is the crank angle sensor in which case there will not be any spark on the wires even though the starter will swing the engine quite lustily without starting.
Take to car to a diagnostic center, and they will attach a diagnostic machine to the car to see if it's the onboard-computer that's malfunctioning.
If the fuses are all OK, and the starter cranks the engine, but there's no firing, the diagnostic system will tell the tech what it is, there are various reasons there's no firing when the engine cranks,
Someone may say check the disable switch on the transmission, but if that's broken, the starter will not crank the engine.
If it turns over just fine and won't start "crank no fire" first spray some starter fluid into the throttle body, if no change in the situation then you know that fuel isn't the issue. Next take a spark plug out, replug it into the wire without putting it back into the engine, set it on the intake manifold have someone turn the engine over and look for a steady spark. "Do not hold it while it is being turned over." if you get steady spark then you know it is not the ignition system. repost findings and we'll get you fixed from there. I will respond within 24 hours of your response. I hope this helps.
Check all the battery and starter cables,particularly the earth cables off the battery.Also check the battery clamps.Check the earthing between the engine and chassis.if this is bad you can get this type of problem.
I have heard of these horror stories about cutting the wires on the ecu and splicing them back together to get the new engine running. We just did a motor and thought we were going to have to do that but the thing fired right up and ran perfect. We couldn't believe it. Anyway, I would try the ignitor, check the fuses, check the oil? Check the immobilizer? How about the ?? There has to be something you are overlooking. Did you get a new ecu with the new motor? Is everything hooked back up? No wires left disconnected? Hope this helps.
I hope you didnt spray starting fluid through the mass air meter. If you did, this will cause a very expensive repair. There is a "Hot" wire in there that will be damaged. Please tell me what engine you have, either a 4.0L SOHC or a 4.0 OHV. The issues could be different, depending on the engine. Both need fuel, spark, and compression to fire with the fuel, and ignition timing and the fuel timing is critical.
