Time for a Update.
Truck finished the National series mid April. And have been chasing a miss all season.
In the end bit the bullet and replaced the plugs, Lead's, Rotor and cap. which did nothing except lighten my wallet. Still scratching my head. after a bit more use, pulled the plugs to check on them. And #2 looked as good as new, where the others had a bit of colour. 2 possible causes, Spark or Fuel.
Spark - New Plugs and the timing light showed a flash, so that was working.
Fuel - Had Fuel pressure, had power to the injector, but no click click when the engine was running. Big screw driver on injector to ear is a great diagnostic tool. Deep in the spagettie wiring from Speedie to the ECU plug it was disconnected. Bummer so easy. Oh what a difference when all the cyclinders are woring
The Son took it to mud fest...... Not one of my smartest choices. One dead motor. The bearings are now in the sump
knock knock, squeek, squeek.
Back to the drawing board. I have a latter model Toyota V6. 1MZ-FE, it has COP and Crank and Cam sensors and all alloy so 50kg lighter, and an Evo X turbo. So lets start the Journy again.
Thanks for all the support on the last motor. I will start a new thread for the next motor.
