When battery terminals are reversedly connected, fuses and grounding circuit would be affected. Recheck all fuses, fusible links and grounding circuits first. Use a test lamp or DVOM to test. Visual inspection is not accurate.

Thanks for replying but could you explain this abit better as I dont understand what a test lamp or advom is exsplained in my first question that I had two different diagnostic checks done and one of the mechanics got my ecu reconditioned and checked all the fuses they where fine but it still didnt fix my car my battery is run done and it was a new one I bought that was put in wrong way so do you know what other damage could have happend and if I bought another battery would my lights and other things work

A test lamp is a device with a probe with a bulb on one end and a wire with a clip on the other. It is uesd for testing the presence of battery voltage which would light up the bulb.

DVOM = Digital Volt Ohm Meter. It is a meter used for testing resistance and voltage.

You need to understand the basics of electrical trouble shooting to use the above.

Can you give me a clear explanation of your present condition?

Can engine be started? If not, what is missing, fuel or ignition sparks?
Are you able to crank the engine?

Hi thanks again for answering me well what is happenning now is absolutely nothing but I think the battery is done we have tried to charge up the battery but nothing what I was asking is do you think if the mechanic did fix the ecu would it help if I bought a new battery as the mechanic that fixed the ecu said it must be a wire and would have to get a diagram went away and never came back with 290 pounds andhasnt even got in toutch with us that is why iam trying to get a opinion of use before I put anymore money as the other mechanic I got said it was the fuel pump took 250 pounds and hasnt returned ithier I would be obliged if you could give me your honest opinion on the situation of my car I know you can only say what you think but it could help a bit thanks

If engine is not cranking, there are a few possibilities.
1. Faulty batery. Use a DVOM or battery tester to test the voltage of the battery. It should be more than 12.2 volts.

2. Starter. When starter fails, there would usually be some clicking noise and the dash lights would go dim.

3. Power supply. Are the dash indicator lights showing when ignition is turned ON?

The ECU is not responsibble for cranking, unless equipped with immobilising functions.

You need to describe the problem in more details so I can understand the problem better. ECU can be damaged by reverse instalation of the battery but seldom occurs

Check all ground circuit connections. Use a jumper cable to connect between the battery negative terminal and engine to see if it helps.

Recheck all fuses, especially the main fuses.

I feel iam being annoying to you I will thank you for your patience before I had any faults after the battery was put in the wromg way it drove alright till the battery ran out of charge everything was working except forthe tail lights and dash board but on the journey the ereal went down and up andwe manage to the garage put petral in it started again and then the batery went we got arecovery man out he checkrd the fuses and said none of them where fused and put it down to suspected fuel fault that is why we got the mobile diagnostics done but what they done hasnt changed the situation iam at my witsend with this and I must be giving you a pain in your head but thanks

No worries about asking because if you do not understand you never would if you do not keep asking.

Problem is we do not seem to be communicating on the same frequency.

I believe you are not mechanically inclined towards automobiles so we will us start all over again, with me asking you questions and you filling me in so I can understand the situation and proceed with recommendations.

1. Can engine be cranked? Ie, engine is turning but not firing up.
2. After reversing the polarity of the battery, reconnecting the battery, the engine was able to run without anything being replaced, not even fuses?
3. After the engine was running, was any indicators showing on dash?
4. Was taillight and dash lights working before battery replacement?
5. Did the charge indicator in dash turn on prior to engine stalling?
6. Presently when ignition is turned ON, are the dash indicator lights such as oil, charge, handbrake and other warning indicators showing on dash?

Thats good, at least now I understand the problem and we shall start with the basics.

We have a power supply failure and we need to get that working before we worry about others.

Below are 2 links explaining how to use the test lamp and DVOM in details. In your case, getting the test lamp should be sufficient for now. They should be easily available at parts stores and would not cost much. Get one and you can start some DIY yourself.

https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester
https://www.2carpros.com/articles/how-to-use-a-voltmeter

Locate the fuse box under hood and note the location of the various components.

Connect clip of test lamp to body ground or the battery negative terminal. Point the test lamp probe to the positive to ensure test lamp comes on.

At either side of MAIN (80 A) fuse you would notice a bolt holding the fuse. Use the test lamp to probe the bolts on either side and if test lamp lights up, the fuse is good. If only one side of bolt lights up, the fuse is bad and has to be replaced.

If above is good, remove IGN fuse and put it aside. Unplug the ADD fuse and plug it into the IGN fuse slot. Turn ignition on and if dash lights comes on, the IGN fuse is bad and has to be replaced.

If you have a DVOM, you can test the fuse to check the resistance but without it, you can still use the test lamp to test the fuse.

There are two types of fuses, one is with 2 protruding ends whereas the other has 2 recess slots.

For the protruding type, hold one end of the terminals to the battery positive terminal and use the test lamp to probe the other end. If test lamp works the fuse is good.

For the recessed type, use a wire to plug into one of the slots and hold the wire to the battery positive terminalwhile probing the other slot.

Similarly, test all other fuses to ensure they are in working condition.

We start here and let me know the progress. For the guys who took your money, go get the money back. Pay to me, lol, just joking. These are the black sheeps of the automotive industry and from what you have described, I believe they are not qualified mechanics.

IGN Fuse 2 ( 40 A)

Hi I did what you told me the battery didnt have much of a charge bought anew one checked my fuses well I think I checked all of them I replaced afew the dashboard light is on now and tail lights go all my lights seem to be fine now the engine is trying to start now but still wont start the fuel gauge doesnt move ithier when I turn the ignition on but oil can brake and battery show on the dash board so what do you think I can do now or do you think ive forgot to check any of my fuses I looked over my handbook and I have an immobilizer and acode I tried to put the code inbut the immo isnt blinking which is what the hand book said it would do so cant get code in do you think I need to do that or are there a fuse for that to I have to thank you again as things seem to be happenning now at least I have all lights working only wish I could get it going any ideas now

Since the fuel gauge did not move, ensure you have fuel in the tank.

Locate the DLC at left side of ebgine compartment. Use a jumper wiare to bridge terminal FUEL PUMP and (B+). Turn ignition on for 5 seconds. Ensure there is fuel pressure. You can disconnect the fuel line near the fuel filter to test if fuel is flowing when ignition is turned on.
