Car will not start, no spark from plug need HELP!
I just had the engine rebuilt last week. Today I put the engine in and connected all the wires. When I went to crank the car it turned over and over, but wound not spark. I checked the connections to the coils, they looked in good shape. I checked the crank position sensor connection looked good. What am I missing? Can you give me more ideas of things to check? Check engine light is on for a cat, but that was previous also, that's not the problem. But engine turns over, and over fine. I don't smell gas, but can hear the fuel pump after I put the fuse back in. Someone please help me? I also checked all the fuses.
thanks,
thanks,

What is the ESS?
Amyrate, I did replace the motor. I will try and press the brake pedal 20 times in the first 8 seconds. Would that cause the coils not to spark?

If you haven't reset the Eccentric Shaft position Sensor, it won't know when to fire/spark. Turn the key to the "On" position and press the brake pedal 20 times quickly and you should see the gauge sweep halfway and back down. It's now reset, turn key to off then try starting.

Did you check the firing order for the coil packs to make sure you plugged in each one correctly? Also how do you know you aren't getting any spark? Who rebuilt your engine? Is your front stack/hub wobbling at all? Are your fuel injectors connected in the right order? when you remove the plugs can you smell fuel on them or are they dry?
You have a billion other threads regarding this engine install please keep all the posts in one thread so we know what you have tried and what you haven't.

I have a diagram of fuel injectors with wires. They ate good. A local guy, Luis Canizales. Probably the best rebuilder their is. Yes, the injectors are dry. I checked the spark by pulling the plugs out and touching them to a ground. And also hooking a timing light to them.
A front stack/hub?
Thanks!

front stack is what your main drive belt pulley connects to. remove all the belts and disconnect the ess sensor then have somebody crank the car as you watch the pulley.
If it has even the slightest bit of wobble....
Ehhh I'm done search next time I already walked someone else through this process.

It looked okay. Straight.
I mean condenser. The condenser that goes to the coils. It grounds on top of engine. From what I can tell the condenser gets power them powers the coils

The condenser sits in front of the radiator and allows compressed freon to cool down before the compressor compresses the gas again.Tthat is part of your HVAC system.
Your coil packs are individual units, there is no distributor. They get their spark from the 12 volt system in the car. the coil packs are regulated by the PCM the PCM tells them when to fire. The way the PCM knows when to fire is from the ESS which sits next to the main dive pulley and gets it reading from a metal plate.
If the front stack is off balance even by a little that pickup plate will be passing by the magnetic ESS at the wrong times causing the ESS to not read properly. Which will also cause the coils to fire at the incorrect times. Also if the firing order is incorrect the coils will send the signal at the wrong time. These connections should have been labeled from the get go. In theory you could trace the wires down to where they terminate at the PCM and run a continuity test for each line.
I am 99% sure your front stack is off balance, I did this myself on a rebuild and I've seen a few pro builders do this as well. However you could have completely fubared your coil pack firing order and that could be causing the same issue. The other alternative is that your builder reused questionable parts and your engine needs a few more cranks to get compression up again.
