I cant get the car to start the starter is working, i have changed the sparkplugs, and it is gitting fule. plug wires look good still, but havent changed them yet.

Are the glow plugs single or dual wire if they are twin or dual wire one wire is positive and one is negative. I will base this on twin wire
I hope it is a negative earth system as I won't bother with positive earth instructions at this stage.
Get a multi-meter that has alligator clips on the cables attach black to a good ground then with the solenoid power wire removed on the starter (so it wont crank) get someone to hold the ignition switch in the on position, then test each pair of wires one will show voltage this is the positive one (mark each positive wire) now release the starter switch and change the multi-meter to ohms test the wires that did not show as active they should show good low resistance (hopefully 0) connection. now you can reinstall the glow plugs making sure positive on the glow plugs is paired with active positive wires that were marked then attach ground wires to the glow plugs.
Reattach the solenoid power wire and try starting it

Could be a short in the coil for the sparkplug. Check the magneto- pull the plug wire off the spark plug and hold it close to the frame of the while someone tries to start it. Keep all parts of your body clear of the mower- only hold the sparkplug wire. When the motor turns over, verify spark from the wire to the frame. If no spark, you likely have a bad magneto coil. If you have a good spark, try taking the air filter off and use some engine starter fluid (not much) and then try and start again. If it starts and runs for a second with the starter fluid, you probably have a problem with your fuel not getting in, which leads to troubleshooting the carb and intake.

1998 acura rl replace fule pump, and check fule relay main and it was good, but still no fire to sparkplugs

Have you checked the crank sensor? They are a common problem item on Jeep vehicles.

That little wire needs to be plugged up. When you click start, that wire activates the solenoid which in turn activates the starter. Note that the solenoid is also attached to the starter.

you can bypass and test starter motor before hand check battery /wiring /fuses/some times a Little tap on starter will git it going if that works it is most likely starter motor / there should also be a starter solenoid that you can use to do the bypass/git a repair manual/ here or at your local library.feel free to ask if you need any further assistance/ please let us know how much mechanical experience you have / some / allot/ none.? we want to help you git it fixed safely.

If the starter/Battery are ok.Check for spark by pulling off a sparkplug wire,have someone try to start hold wire near sparkplug tip you'll hear the spark jump to the plug tick..tick..tick..sound.Be carefull to hold wire just far enough to hear spark,also this is the secondary circuit from the coil it's high voltage wear a glove.If you smell gas youre geting gas if no spark it is 1 of the following.Bad Coil, or ignition modulator, crack in distributer, cracked wires that cause spark to not reach plugs.Good Luck.

Check the gas cap, take the cap back off the distributor and check to see if there is any play in the shaft (back and forth) and check for excessive play in the pinion gear. If it seems fine you can also check for play in the timing chain. If you are in the habit of not keeping the fuel tank full it may be a water in the fuel problem or could be water in the fuel. Double check your work on the tune-up, make sure that you didnt foget something. It happens to the best of us. Is the air filter fine? You can also check vacuum lines and the ducting between the MAF sensor and the plenum. Well good luck.

WARNING: Risk of Electric Shock

Check your spark plugs and wires yourself. Remove one sparkplug at a time from the engine block, plug the wire back on, place the sparkplug on the engine or vehicle body so that the outer thread of the sparkplug would touch the body, or engine (GND) you can secure it with a cellotape or so. Turn the ignition key to the START position and when starter is spinning wach for high voltage sparks appearing between the body,engine or gasket and the tiny black end of the sparkplug called electrode. If there's a sparks, than it's fine, othervise try to get one working sparkplug and to retest this. If now it works then your sparkplugs needs to be replaced. Othervise check the resistance of the high voltage coil primary windings. this should be something between 0.2 and 10 ohms, when coil is disconnected from vehicles wiring. I just do nts remember the exact figure. If multimeter doesn't show anything, replace the coil, otherwise check if the supply current is flowing to the coil plug when IGN is ON. If it's fine then check the COM line at the same plug, using analog muldimeter is the easiest and not harmfull way to do this. If COM isn't comming You might need to go deeper into ECU, or even to replace it. If COM is fine then it would identfy that coil itself is faulty.

Update me about your progress

Good luck

you might try a salvage yard starter.i know you said it was good before but things happen ,,its worth a try anyway
