Fzj80 landcruiser no start no spark

We started to test spark coming out from the igntion coil at the distributor and no spark, we tested the coil had power and that the efi relay and fuse was ok, then it became a matter of using a scope to test that the crank sensors in the distributors where working, we scoped and found that all was good and that engine ecu located behind the glove box was receiving the signals, we then found that the ignitor next to the coil controls spark to the coil and the injector power, so we checked that there was power to the injectors was was present we then used a wiring diagram to pin point output the ignitor grin the ignition coil, the reading where not a normal output that you would expect so of course we blamed the engine computer for being silly and not doing what we wanted off course just blaming a part will get you into trouble if you don’t first test all the power and ground circuits to the engine ecu, so we did that and still nothing , we replaced the engine computer and still the same thing, by this stage I was shaking my head thinking I have really missed somthing, so it was back to scoping all the componentry again to check that I hadn’t missed something buy mistake

Dangers of running a low profile tyre flat

The dangers of running new style low profile wheels flat can be dangerous, in the picture below you will see how a VE commodore with 19 inch wheels suffered from a blow out tyre.
The tyre was on the rear of the vehicle and the geometry of the suspension on the VE Commodore has a -1.00 degree of camber so when the tyre is flat the pressure on the inner side wall is the target. The Damage to the tyre is non repairable and even if the tyre had not cut through all the way the inner side wall of the tyre would have still suffered great damage.

It is P & G Motors recommendation to visually check the tyres for pressure every time you drive the vehicle and check the pressure once or twice a month.

We believe that showing you pictures of our work history will help you understand the importance of correct maintenance and service of your vehicle. Read More
