Fuel Pump Problem?

My car won't start at the moment and trying to get to the bottom of the problem.

The starter motor is cranking but the engine just won't start

Lately I have been having some problems which might help to diagnose this problem:

One time I had low fuel and the car wasn't running right. It had flat spots when I was revving it in the higher revs. Also at one stage it did stall as I was driving along.

I refueled the car and it seemed fine after that. Then yesterday as the fuel tank was close to empty the same problem occured (Car flatspotting at low and high revs this time and then it stalled as I was driving).

Today I can't even start the car. It sounds like a fuel problem to me.

I have recently changed the spark plugs and did a compression test (close to 150psi across all cylinders). What are your thoughts?

Hey r33cruiser

I got NRMA to come check it out - and they fixed it. Supposedly the plug for the crank sensor wasn't on properly.

Does that explain the flatspotting and engine stall though? Anyone care to comment? Going to go for a drive soon to check it out.

Do you still have the stock pump as far as you know? it could be explained by a 20 year old fuel pump, sometimes it's the wiring, though usually it takes a new pump to expose the wirings in-ability to supply more than 11 amps (I think thats what the stock pump draws max)

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
