Hiluxmad For what I have learnt from the diagrams and from talking to Sideshow (many thanks) the sta on the computer is an input, it comes from the switched ignition that starts the starter (that way the computer can see that your trying to start the engine) this also goes to the fuel pump so...

Got one step closer today, got the engine to fire up but it wouldnt continue running. Checked all injectors and they are getting their pulses, cleaned all the spark plugs and hook up the vacuum line for the brakes. Have to test it again tomorrow, getting to late to start it up with just the...

Hi, Checked coils and Igniters and they have the ign 12V, also checked that Igt1, Igt2, Igf1 and Igf2 have continuity back to the ECU. Check the diagnostics, in normal mode it shows no fault just the continuous flash and in test mode it shows code 42, which from reading the Auto faults...

Thanks Sideshow for test my ECU. Have wired in the STA and NSW. Engine cranks over fine, ECU is pulsing the fuel injectors (so getting fuel now) but have no spark at the spark plugs. The igniters have constant 12V from the ignition, and I have strap a large battery cable to them via the...

Hi guys Zuffen, I have checked the following Got the right connectors plugged into the ECU. Opened the ECU and tested the voltages at the board and all input voltages 12V Batt and 12V Ign is spot on, and 12V from Main EFI relay is good to. I was told when I bought the engine box and loom...

I checked all the earths I could find, made sure they were tight, tested the continuity and all were good. I only have the master power relay being energised, all other relays are off, the outputs from the ECU to energise the relays are just floating at around 200mV

I have 12V from the Circuit Opening Relay but dont have any outputs from the ECU on any of the Fuel pins of the ECU: FPR pin (fuel pump speed control output) FC pin (Fuel Pump Power Relay) and STA pin (Starter output to Fuel Pump Power relay) All the above pins are floating around 200mV. I...

Hi, I am putting a crown V8 in a HQ Monaro. I have followed the wiring diagrams for the 4 relay (duel speed fuel pump) setup but Im having trouble getting the fuel speed relays to operate. The main EFI (master) relay energises when the ignition is turned on but neither of the fuel pump relays...

Hi, I am putting a crown V8 in a HQ. I have followed the wiring diagrams posted here but Im having trouble getting the fuel speed relays to operate. The main relay enables when the ignition is turned on but neither of the fuel pump relays energise to start up the fuel pump. The engine check...

techo What is the XDI stand alone ignition, is it designed just for the Lexus V8 or an after market job programmable for anything?

Hey guys what did you make your sumps out of. I about to start making my sump to fit a HQ monaro just wondering on thickness.

Crown Royal Saloon wiring needed I just picked up a Crown Royal Saloon and there is wiring but its been cut here and there. Ive downloaded KDogs schematics which make it look fairly straight forward but Id also like to know if the 1990 Lexus wiring schematics are the same for the 1990 Crown...

Sounds like a top idea, it would be to see what others had done (might help out with a few ideas).

Just checking I have managed to find a guy selling a half cut at a reasonable price. It is about a 90/91 crown. Are there any differences is output power in the different models(ie crown, soarer etc). Also I have put some data for the stock V8 and plugged it into Dyno 2000 and it gives out...

Cool, thanks guys.
