So you can set and adjust timing, and you have spark. Disconnect the Cas and pull the plugs out, crank it for a little bit to dry out the excess fuel, then put the plugs back in and reconnect the Cas and try again.
Check all you wiring for the temp sensors, there is 1 that must be connected as it tells the ecu the temp, if this wire is broken then the ecu goes into failsafe mode and won't start
There's your answer Jono.
Craig, I laughed at Nigel for listening to your advice, but just sometimes you come out with some good ancient info from the VR4 archives that is your brain lol.
Do you know which plug it is? As in what it's for? I thought there might be something like that but I wasn't sure.
The night before I went over because he couldn't get it running and he didn't have his injector resistor pack hooked up (he had it switched with the idle stepper motor). After connecting the resistor pack up, the engine fired up which makes me think it's gotta be something simple, cos it was working then, which was like 24hrs before and he said he didn't change anything since apart from putting the exhaust on and filling the radiator with water.
I was annoyed that I couldn't get it started but there were so many things wrong with his car it was kinda futile and seeing I rode there I didn't have anything with me so I gave up lol.
His wiring loom is an absolute mess and virtually nothing is hooked up apart from the essentials.
Two of his coil pack terminals are way corroded (looks like electrolysis), and he's getting a weak spark on the plug (dead battery). His injectors are firing but it seems they are spitting out heaps of fuel and extinguishing the spark. I know the ECU allows the injectors to pass more fuel than usual during start-up and he is using 560cc injectors, but his fuel pressure is ~32psi and he says his ECU is 'chipped' for 560's.
Having said that, it should still run, it'll just run like shit.
We motored the engine without the spark plugs or fuel injecting, cleaned and filed the spark plugs, rotated the crank to TDC and checked the alignment of the CAS. Whacked it all back together and threw aerostart down the butterfly but it didn't even splutter.
I'm not sure if the spark plug leads were in the right order but considering the ignition is a waste-spark system, I just plugged cyl 1&4 to one coil and 2&3 to the other. Then swapped them to the other coils as there was no success.
What you're saying would make sense though dude. Good luck finding the plug in that mess Jono! lol
Let me know how you go buddy, I'll have more time after Thursday if you need any more help.
Cheers.
