If you put a stronger fuse in, it will burn the spot were the short is, may cause a fire !!
Need to find out what is making it blow the fuse ?

Ok So the air injection is designed to blow cooled fresh air into the catalytic converter to aid in its transference of gases. You may need to get a tube welded on to the "cat" to attatch to the air injection one way valve. An experienced exhaust shop will know right away what to do and shouldn't take but an hour and maybe $50. Great engine on those cars. Let me know if you need anything else.

Is this a 2.3 or 2.6. I may have a manual for you.

Hi there, the wiring sequence that I have is for the UK, I dont know where you are but I hope this helps
pin 1 Yellow L/H direction Indicator (turn Lamp)
pin 2 Blue Rear Fog Lamps
pin 3 White Earth Return
pin 4 Green R/H direction indicator (turn Lamp)
pin 5 Brown R/H Tail Lamp & No. Plate Lamp
pin 6 Red Stop Lamps
pin 7 Black L/H Tail Lamp & No. Plate lamp

you will have to trace the wires from the wiring loom and light clusters off the car to splice in the towbar wires which is quite easy, the chassis should have location points for the bracket, just make sure that the tow hitch is central and not obscuring the number/license plate..
Good Luck.

Verify fuse for horn is good.
Check for voltage at horn when button is activated
If voltage is present insure horn is mounted firmly. If there is rust / dirt remove horn and clean both the frame and the horn and remount as a bad ground will prevent it from working also.
If voltage is good at fuse and not present at horn when button activated it could be bad switch or wiring

I would check the Crankshaft postion sensor and go from there.

Your best bet is to shop around local shops like Midas, Tires plus, etc... they have specials and are considerable cheaper than dealer. If you bought parts yourself and did it yourself would be least expensive, but if you've never done wheel cylinder replacement before, this is NOT the car to learn on.

is the engine working well?
Check engine oil and let sombody test sensors. If engine works good.

If you have inspected all of the fuses in the main fusebox, and they are OK, your problem is going to lie inside the instrument cluster itself.

You could have 2 problems. The hard start in the AM could be a bad fuel accumulator and or check valve in the fuel pump. The engine cutting out could be a bad idle stabilization valve, dirty throttle body and housing or a bad 02 sensor, could also be just a CO adjustment. Where are you located?

you may just have an air lock in the engine water jaket,,bleed it out,, fill rat up,,,find top hose with bleed screw in it run up motor and undo bleed screw till only water comes out,,,keep rad toped up,,,job done?

Synthetic oil won't damage seals. You can use it. Sometimes seals that already leak will leak worse with synthetic but it won't damage them.

its 18yrs old so decide do you change the head gasket or scrap it??whats it worth in place of residence here its might fetch a 1000euros if a petrol now a diesel manual like this could fetch 3000 euros or more if in good condition

Whovever did the head repplacement should have replaced the chain. If they did not then you probably lost teeth on the gears and chain went wild in there. Back firing can mean alot of things and can definatly support what you are saying.

If you redlined the vehicle any number of things can happen with no load to slow the engine down.
