Okay, I did an engine swap on this car because the first day I drove it the motor blew due to a leak I didn't know about. Anyway, swapped the engine and now it is not starting. Finally got it to crank after finding a bad ground but still won't turn over.

I believe I'm not getting any spark is the missing component

I'm having coil pack tested.
I'm getting power to the connector but i'm not getting spark when I try the ignition. Coil test to look for spark or my light tester.
But regardless i'm taking it to have it tested.

Spark plugs and wires look fine and tried two sets of wires I had from old engine.


Now these cars are known for corrosion in fuse box and mine did have some but the wires from what I can see looks to be good to the computer. Can't really see in the fuse box unless I completely remove the whole harness, because it's wired direct to the terminal not like a plug in connector deal. But there are like 6 fuse terminals that are not getting power.

And now we get to the issues that may have something to do with it.

Battery was bad but before we knew it was. We were working on it at night and my brother hooked it up backwards and the light show began.
Fuse on the battery looks to be perfectly fine, but haven't taken it apart to test it.

Also while swapping the motor somehow my alternator connector got broken off. I soldier it and put it back together. But then someone was helping me and had to take it off and they broke it off and lost it.

Ugh

But anyways I don't know what that plug actually does and if it may be causing my no start issue or if its electrical or if it fried my ECU. Please help I'm not a mechanic at all and can't afford Ford mechanics, lol.

Hi,

I'm trying to understand. A fuse shouldn't have a ground. If it did, it would blow the fuse. Can you take a pic of what you are dealing with and upload it for me to see? Also, here is a link you may find helpful. It deals with checking wiring. Also, check the mega fuses in the high current battery junction box. See pic 2.

As far as the no spark, if you have a live data scan too, see if there is an RPM signal when cranking. A bad crankshaft position sensor will cause a no spark condition. Take a look through this link.

Also, if you look at the attached pic, I highlighted the crankshaft position sensor. Make sure it is connected and the wiring is good.

Let me know what you find.

I have already changed the crankshaft sensor and the cam shaft sensors. I'm at work so will have to take pics when I get home.

The ground I was talking about was a loose ground to the block causing it not to crank I fixed it. So now it's a crank no start.

And I have a code reader but I don't think it runs live scans.

Should I get one?

I guess it does say it does live freeze frame.

Hi,

If it does the live data, see if there is an RPM signal. Also, when you replaced the engine, was the engine the same year, make, and model?

Let me know.

Yes, it said it was only difference was it was automatic transmission so I switched that out and went from there.

I have a generic code reader nothing special but i'm about to head out to it in a bit to rescan it.

Engine light staying on but no codes (to my scanner anyways) stored.

Hi,

I have a feeling it is related to the crank sensor. Interestingly, they can fail but not set a code. I'm not saying the new one is bad, but something may be damaged at that point. If the vehicle has a tachometer, see if the needle moves when cranking.

Let me know.

Okay, so I had my wife tried it and she said that it isn't moving when they crank it. I'm at work but should I stop and get another one. Would this also cause me not to get spark to my coil? Because I tested the coil plug and I have same voltage from battery but nothing at the coil pack took it off and a video I watched said it was needing 16,000 ohms and I had about 400 tops. Unless I'm not doing something right.

Hi,

If the crank sensor is bad, yes, you won't get spark to the plugs.

Here are directions for determining if the sensor is bad or if there is a wiring issue. This is extensive. The attached pics correlate with the directions.

If the new sensor doesn't make a difference, this is what you will need to do.
