installed new preprogram PCM now it cranks, no start?

If the engine ran before the PCM swap it is not programmed correctly. Can I ask if the security light is flashing? If so, this will be the problem, you might want to try a hard system reboot.

I would also check the fuse # 16 and 17 in the fuse panel under the hood. Also, you might want to try swapping out the auto shut down relay as well. Check out the images (below). Please let us know what happens.

car was not starting before installing new PCM.

no security light is not flashing.

asd fuse and fuel pump fuse has power.

16 and 17 has power .

fuel pump only come on when I ran a jumper wire to fuel pump relay 30 and 87.

So the engine was not running and so you replaced the PCM?

correct the only codes I got were p684 and p1282.

the codes are p1684 and p1282 not p684.

I have another car with a small crack in engine near oil pressure sensor, what's the best glue to try to seal it?

i check fuel pressure and it has 50 PSI and a new fuel pump and new filter, new injector. 01 town and country

I got spark now finally says scanner 9 sparks I just won't start.

How does the engine sound when cranking over? Can you upload a short video of the engine cranking so I can see if the engine has a problem? If not, we should do a compression test.

how do I upload a video?

now I'm getting spark at the spark plug but not at the coil.

on my scanner it shows RPMs while cranking 4-400.

Okay that is good this means the crankshaft sensor is working.

P1684 - Battery/PCM Power Interruption:

P1282 - Fuel Pump Relay Control Circuit Malfunction:

Do you still have these codes? I have seen the coil pack go bad and cause the intermitted spark issue. I would swap out the fuel pump relay and then clear the codes again. Take a video with your phone and upload it here in your response like an image. Check out the images (below). Please let us know what happens.

i install a new coil I got from Amazon, still same getting RPM and no start. I smell a heavy fuel smell in the engine area.

Thanks for all you have done for me. I gladly appreciate it.

my phone has issues uploading videos.

Lets try checking for spark from the ignition system.

Please go over this guide and get back to us.

when checking for spark car started for 30 second after I tighten down the coil more, the coil was a little loose.

scanner show 700 RPMs before I shut it off.

So when you tightened the coil it stopped running? If so, the coil sounds bad, and I would replace it.

no when I tighten down coil and ran better but not staying running.

I start and ran for 5 seconds like it losing spark.

there is old gas in there I'm going to take it out, idk if that's one of the problems, I tried to siphon it in past but did not work.

I will do everything I can, I urgently need to get this car running.

Spark plugs are wet with fuel!

Lets check the compression to see if the engine is in good shape, this guide can help:

I don't have any way to check compression.

what does it mean when spark plugs are fuel flooded wet with fuel?

Are all the spark plug wet with fuel or just one?

a few on them are wet.

car has a strong crank, so I think I had good compression.

car does not start with starting fuel.

Yep, this is a sign of low compression, I would get a gauge to check it so we don't chase our tails, we need to make sure the engine is in good shape.

I think is something with the add relay, it doesn't crank when fuel pump or ASD relay remove, I am lost.

ASD relay problem that's what I meant.

with this car every time I fix it; rats eat the wiring up.
