They won't swap.
No. The 99 Escort takes a 97 to 02 transmission.
the engines used in both of these cars are different. The zx2 engine is a dohc while the escort is a sohc. Physically the zx2 engine will fit into the escort SE. To get this install to work will require wiring, ZX2 computer, fuel system upgrades. Additionally, the escort se transmission will also bolt up to the zx2 engine but will require a little work as well. This swap has been done and information for such can be found on teamzx2.com and feoa.com
I believe that only 96-99 can be swapped 2000 and newer will not fit correctly.
Swap the relay with a known good relay.
You should be able to, the only differerence is a zx2 is a dual cam engine, both are 2.0, so the basics are there the same block, which means same bolt pattern.
Okay- I own a Ford Escort LX, 1994 4-dr, and for all my problems, and help I use this forum site called feoa.net (ford escort owners association), look under "engine swap" and either look for the biggest engine, or post your own topic. It's an amazing site,
No because they are different motors which means they are different transmissions.
Swap Your Ride
You could swap out for electric fans, you could upgrade the fuel injectors, add a cold air intake, add a good exhaust system, add a turbo.
Yes you can swap them. Is it a direct bolt for bolt swap? Probably not.
