Just bought 01 trooper engine will not turn over when you try to start but is not locked up. Flywheel can be rotated from access panel underneath but engine dose not turn with it, do I have a broken flywheel? If so need repair info since I do all my own repairs this is a first flywheel issue for me

Do you have an automatic or manual transmission? If it's a manual, the flywheel is pretty tough and hard to imagine it cracked around the center. I'd more likely expect to find the bolts sheared off, and even that would not be common.

My vehicle will not start. All the lights come on when you turn on the ignition over but nothing else happens. We check the battery and tried to jump it from the fuse box area.

Sounds like it may be a faulty starter motor if you properly boosted the battery. I would check the voltage of the battery first to ensure it is over twelve volts and does not drop below 9.6 volts while a second helper tries to start the vehicle.
Once the battery checks out you can look at the starter motor. The larger main cable at the starter should have battery voltage. The one wire connector (signal) should have battery voltage while the ignition is in the crank position.
It is also good practice to inspect the ground cables as a loose ground can cause a no start condition.

Daughter ran errands in the a.M. All was fine went home and then later the trooper would not start. There is a check engine light and a reduced power light. The car had a check engine light before this but was related to EGR valve. EGR was replaced and engine light went out but came back on. Now a reduced power light is on and the car will not start. Check battery it's ok. Hear a clicking by the starter but also read that it could be wiring harness. Can't pull codes because don't have equip and can't get it anywhere without being towed. Any suggestions on what to check.

So you have a crank no start?Or a no crank no start?A reduced performance light can disable a restart depending on the issue. Your best bet is to get a code reader and see what codes you have. You have two choices get it towed to a shop and have them fix it. Or buy tools and try to fix it yourself. Getting the exact code numbers is your first step. You can do the basics check for spark actual fuel pressure and check injector pluse but if the computer is shutting it down or bad sensor your not going to know. Thats why I would see what codes it has first its best to have a scan tool that reads live engine data for diagnose. On amazon they have them for 50 something dollars.

Just installed a reman. Engine and after replacing it, started it up and it fired right up and ran it, no problems. Tried to start it but no crank, you hear the starter maybe dragging and not actually engaging. Checked all connections, all is well there. No service lites are on, checked relays to the starter and starter, all seem well

Hi there,

you will have to check for power at the starter main terminal & the solenoid when on crank, if ok then starter is faulty. If no power at solenoid check starter relay.

Trooper battery has been changed battery cables have been replaced. Still when I shut off my trooper the chances of it restarting is random. I replaced my fuses and think maybe the alarm fuse is draining my battery what do you think?

Will not start after I shut it off maybe sometimes if I jump it

So if you pull the alarm fuse does the battery still go dead?I have seen batterys test good and still not hold a charge. We need to do a parastic draw test to see where the draw is or even if you have excessive draw.

I pulled the fuse and jumped my battery but it acted like it wanted to start but it failed and I tryed to start it 2 more times after that and it just clicked as if there was no connection with the car jumping my battery. I didnt here the other truck kick down. Then I begin to smell burning wire on the drivers side. At that time I disconnected the cables and the battery post felt as if it had been running for hours. But it wasnt. I have begin to think mabey it may be my starter relay fuse under my dash or a wire that leads to my relay. Please help I cant afford to take it to a professional. Problem solving and determination is my key. Mom in need '0

The vehicle won't start. It slowly turned over and just acted as if it had a weak battery. At first I thought it needed a new battery. It's been about three years. I replaced the battery and it still won't crank over. I checked the battery and it appears fine. Help?

If the starter spins the engine very slowly, even with a new battery, there is very little in the circuit that can cause trouble. You'll need a cheap digital voltmeter and a helper to turn the ignition switch.

Start by measuring the voltage between the two battery posts while your helper cranks the engine. The industry standard is it must remain above at least 9.6 volts, but realistically, you should have 10 - 11 volts with a new battery. If it is too low, either the battery is run down or the starter is drawing too much current. Connect a large battery charger with an ammeter. First charge the battery for half an hour at te lowest rate, then crank the engine with the charger still connected and turned on. If it cranks normally, we need to test the charging system. If it still cranks too slowly, feel one of the large battery cables. If it is hot, or if the ammeter on the charger goes real high, the starter is drawing excessive current. Either the starter is partially shorted or, less likely, there is internal engine damage.

If the voltage at the battery posts, (not the cable clamps), remains fairly high, say around 11 volts or higher, and it still cranks too slowly, we have to hunt for a connection problem. That is done by moving the voltmeter probes to different places in the circuit.

Holler back when you've made these checks.

Was driving my car down the highway and the clutch stuck to the floor. Coasted to a stop. Had to get it towed home. Got opinions it was either master or slave cylinder, most likely slave cylinder. So we replaced the slave cylinder. Bled it out to get pressure in clutch. Car still wont start. Made a grinding noise at first. Sounded horrible. Coming from the engine. Now it doesn't grind but still wont start.
Not sure what the problem is.
Any help would be appreciated.
