Well done mate. Glad to see it running. It's always satisfying to fix a problem yourself too.

It's running and after a full day of work I'm so happy :)

Was a range of problems:
Cranking signal from key, used black/yel and should have used black/red
Dirty contacts in TPS
Injectors 2,3,4 jammed closed
Fitted new NGK Plugs also
AFM faulty at moment and wont rev past 2000 rpm

At least she runs and quite sweet except the AFM so cheers for the help guys.

any time man

Sweet guys - got a list of things going to try on weekend after I source some generic plugs.

Motor has got heaps of new earth leads fitted but will look at injector circuit again and if have no joy will pull injectors out and have a look.

Perth ute will be intouch next week if I need that spare ECU or try my ECU in your ute.

Cheers guys.

if it turns over he should be able to get a reading - its not going to be perfect but its going to give a pretty good indication.

It's going to be pretty hard to check the base timing when it doesn't run.

Even though you have mentioned that you checked the resistance of the CAS with no abnormal results and that you haven't changed any of the CAS settings, have you checked what the base timing is with a timing gun?

I had an issue with getting my CA started that was due to the CAS being waaaay out even though it hadn't been touched.

Get new plugs. Sometimes they can look clean and good but are actually no good. Particularly because they will have burnt the oil away the first couple of times they fired. A good spark out of the engine isn't always a good spark with compression.

There is a $3.50 NGK plug that works that I have always used. You can commit to $25 a pop iridiums but you may not need them so you may as well just the cheapies to rule another thing out.

Do a search around the place. I know I've listed their part number somewhere before.

Run an extra earth to the engine block from a chassis rail. These motors love being earthed well. Mine had similar intermittent starting issues until I ran an earthing kit around the engine bay.

Also check on nissansilvia.com and you will find a complete list of fault codes for the ECU and how to put it into diagnostic mode.

Is the earth and power to the injectors good ? You may have done something bad when those wires were shorted out. Is there any fuse for the injectors ?
Maby spray a bit of aerostart into the intake and see if it fires on that if it does then its a fuel problem for sure.
