SOURCE: Change spark plugs and now car wont start.....1994 ford tarus

Do you have the "firing order" correct? In other words, is each spark plug wire going to the same cylinder it was on before you changed the plugs? If you have done nothing else but changed the plugs then this is the most likely problem.
If when you try to start the car it backfires through the exhaust or backfires through the intake. Then this " IS" the problem. Good luck.

SOURCE: How do i change spark plugs on a ford escort sport

start from the left hand side of the engine as you are facing it, take one out at a time this way you will not mix up the HT leads ok.
Take the lead off number one plug and unscrew the old plug anticlockwise with a socket that fits the sparkplug, once you have done that put the new one in and tighten up clockwise and put the lead back on and push down so you hear a click but do not tighten up to tight or you weill damage the treads on the plug. Just enough so you feel the pressure on the racket. then do the same with all of them.

I hope this help's?

SOURCE: how to read engine cose 1990 ford escort 1.9

On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the engine light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports.
Ford owners can check their check engine light using the diagnostic connector located at the engine compartment by the fender near the battery. Getting the obd1 codes need a couple of tools: a 4 inch long gage 16 jumper wire and a 12 volt test light. Both tools are hooked up to the diagnostic connector and when the IGNITION KEY is turned on (without starting engine) the codes will begin to flash in the test light, not in the dash panel. If there is no code, you will normally get code 11 or 111. On Fords, there are 2 test modes, the KOEO (key on engine off) and the KOER (key on engine running). Both test modes should be used to get the accurate evaluation of the stored fault codes.
Most of the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.

Car hesitates and backfires at lower speeds?

check the firing order of the spark plugs and make sure the number 1 piston is on top dead center and start from that check the marks on the crank shaft pulley if donot match your timing belt(or chain) position is no good and double check all pushing rods.

My 1990 chevy astro van didn't pass smog. Paperwork says it failed the following; Ignition timing: 99 ATDC. Also, ASM Emission Test Results; 15mph HC (PPM) max is 122 measured 127, 25mph max is 102...

the smog test looks like the engine is miss firing, that could cause the timing to be out of whack also, try a old fashioned tune up, new spark plugs, wires, and filters also replace the PCV valve. any time you see the NO that high suspect a miss fire.

IT IS MISSING iVE REPLACED THE PLUGS

Misfiring Escort...
THE Guide!
1- check HT leads, including the main lead from the coil. pull one off at a time and see if there is any difference in engine noise, if a lead makes no difference to the engine note when you pull it off it is broken and you need a new lead for that plug - best to replace a full set since the others will be on their way out too. try each plug and check the leads like this with the engine running, 2- clean/repace distributor cap and rotor arm if it is dirty or corroded, there are 2 Clips, one on either side of the distributor cap, pull em off, take the distributor cap off, look inside the cap, there are 4 pins, are they all corroded and covered in white stuff?, they should be shiny brass, clean them up with fine wet and dry sandpaper, make them flat and shiny again. also still on the distributor is the rotor arm, pull it off, it may need a bit of wiggling - clean this up the same with the wet and dry, get a very fine grade of wet and dry sandpaper since you want the metal to be as smooth as possible afterwards, once the cap and rotor both have shiny metal clean them with mild detergent, rinse and dry them fully, not only to clean them of dirt and grime but also the metal filings from the sanding are "bad" for the distributor.. once dried refit the rotor arm (it only goes on one way, do not force it) refit the distributor cap, make sure its the right way round (make a note of its position BEFORE you remove it) 3- check if air filter is blocked and replace it if it is very dirty - if you think it is blocked try running the engine without the filter and see if it runs better, you know for sure you have a bad filter if this is the case. 4- check fuel filter (especially on 1.0 and 1.3 engines) for blockage and fuel line for blockage (replacement costs £3.50-£5 or so)
apart from that its "experience required" jobs like setting the ignition timing - just get a normal tune up after you've checked out the leads and dizzy/rotor arm which is quite cheap on an escort, you only turn the dizzy and move 1 screw...
Just for reference in case i have misjudged you're ability and you want to try tune it yourself... 1989 MK4 Ford Escort ;-D you didn't give CC so you'll get all engine data for 1989! (petrol)

So check your spark plug gaps with feeler guages if you don't have a feeler guage they're less than a fiver at a cheap motor shop - even pound shop and market stalls sometimes have them.
Apart from that lot - these cars can run bad if the battery is weak, they chug like hell on a half charged or failing battery, so make sure the battery is strong too...
The carburettor jets could be clogged or worn... Inlet manifold could be leaking?
Check the low tension wiring (the wiring on the ignition coil, the two round plugs that puch onto the coil) one red and one green/black/stripey/somethin - trace these two wires around the engine bay and check them for damage and loose connections.
Thats all I can think of right now tell me how you get on, I KNOW these cars... I'll go step by step if you need help checking everything/replacing whats wrong,
------------------------------
Good luck.

ENGINE RUNS ROUGH ,AND BACK FIRES .

Does it get better at higher rpms? If so then listen for a clicking or watch for a spark from the spark plug cables. Change those first and the plugs while you are at it. Double check the spark plug gap. If possible check the timing and adjust if necessary. That you should do first.
