Run an earth strap from an alternator bracket to a chassis rail.

 

I need to do some welding on my flitch panels / damper mount on the right hand side so I'll put a set screw in place and add that additional strap myself.

I'd not really thought about it until this post, don't recall seeing any, wanted to show the OP where they are hence me scouring my pictures, I didn't spot any - need scuba gear out there presently but at least mines already jacked up (been sitting on the quickjacks for a week now with no wheels).

If you go to this thread, there is a sound file attached.

Does your starter sound something like that?

 

Wife said, she could not hear anything out of the norm, I guess starter is ok.

 

Still mowing, hopefully can get back on the Jag tomorrow.
Will be checking and cleaning all the earth,ground wires and will post results of each wire.
I want to thank everyone for the info.

 

Will do Greg, Thank you

 

Up date---Battery cable connections good. Took off coil wires from dizzy cap, placed a screw driver 1/8th inch from coil wire, turned off lights, closed overhead door, cranked engine, no spark from either wire.

Upper coil, dizzy cap, rotor, replaced 2 years ago.

 

The wire from the coil to the distributor? I don't think that will give the desired result. My understanding is that the coil won't discharge unless its triggered by the distributor. Try one of the spark plug wires.

 

ok, thanks

 

took plug wire off put an old plug in it and no spark.

 

is the ignition amplifier to be behind a/c compressor and in front of dizzy cap, if so it is not there, just an empty valley.

 

I happened upon 2 ignition coils that I bought 2 years ago still in boxes
2 years ago A bank was firing but B bank was not, then both sides was not firing ,so I bought distributer cap, rotor and both coils.
When I replaced distributor cap and rotor, all was good so I did not replace coils.

I will replace coils, if no start will replace distributor cap and rotor again.
If this fails I guess I will just have a dead Jag, I dont know what else to do.

If you have cranked the engine and no spark from an HT wire to a plug (providing the business end plug was touching the engine when you tested it?) then it is most likely to be the amplifiers of the coils. The most reliable way to test for spark is to hold the plug lead (the HT lead) about 1/4 inch from the engine intake manifold and watch for a fat blue spark as someone else cranks for engine.

You should also pull a plug and check that it is a bit damp with fuel just after unsuccessful cranking. If it is bone dry then that is an indication of no fuel injection either.

A good plan to change the amps to be sure, BUT it seems unlikely to me that both amps (you are Marelli assume?) and/or both coils would fail at the same time. I know nothing about Marelli systems (happily I do not have to!) but I believe that a failing crank position sensor (you have two, one each end of the engine) can also produce no start because of no spark. Also run the extra engine earth strap before retrying anything.

The Marelli guys will chime in I am sure. But courage as they say over here, it will get sorted!

 

Thanks Greg
No spark, I will check distributer cap and rotor.
After three 5 second cranks, battery drops from 100% to 78% on the Super Start Extreme 900

 

I'm with Greg, it sounds more like a sensor or relay issue.

 

Mac
What do the sensors look like and where exactly are they, same question on the relays.
Thank you

 

The attached should help you.

 

Thank you, Thank you, Mac Allan
I scrolled thru it and WOW, You have no idea how much you helped me.

I have some homemade ramps that puts the bottom of tires 24'' off the ground.
Will get some help to push jag out of shop, turn it around, push backwards into shop, set ramps up, park my pickup outside, hook up winch and pull jag onto ramps.
I dont trust jacking up on blocks and nothing I have will raise tires enough to get on ramps.

I will still have many questions. Thanks again.

 

Thru checking, I know Im getting fuel.
I have cranked engine so much and will still be cranking looking for spark.
My concern, is fuel getting built up in cylinders and exhaust, if so, when I finally get spark , is the whole thing going to blow up.
How do I disconnect fuel pump, is there a fuse.

 

Yes, there's a relay. Above the battery to the right there is a little little black box then two relays. One has a red base and one has a black base. I can't remember which one is which, but the one towards the front of the car is the fuel pump relay. Pull it out and the fuel pump won't run.
