Thread: Intermittent not starting

A good clean around the ABS sensor, and a light tap in with the hammer has resolved the ABS and related EAS issues.

Next test is to thump the petrol tank the next time it won't start.

There's a Schrader valve on the fuel rail in the engine bay which you can use to check for fuel pressure.


First thing in the morning, depress the centre to see if there's some fuel pressure in the rail (it may squirt out so sort of cover it with a rag & keep your eyes clear). A dribble might mean a weak pressure regulator or a leaking non-return valve in the pump.


Next, switch on the ignition for about 5sec (don't crank it though). The fuel pump will operate for a short period to 'prime' the system. Check the valve again. You should have a lot of pressure now (again, keep eyes clear). If not, you have a weak fuel pump.

The last time it wouldn't start, I applied LR Tool #1 to the bottom and side of the petrol tank a few times, and it then started straight away.

Based on that fix I have assumed the fuel pump. I'll still try your test as we'll though, as so far nothing has been what it first seems!!!!

Fuel pump replaced and all seems well with my Rangie. Had a bit of a shudder around 2000 revs though, so cleaned up the MAF, throttle body and air filter, and running much better now.
