Intermittent starting problem with 160 Suzuki engine when hot

[arthur rayner]

Hi all

My car has only 3500 miles on the clock, and today I ran it the hottest so far, up to 6K revs, not constantly. Shut it down, then went to re-start after a couple of minutes, and on one occasion after 10 mins, and the gauges would not run to deflection, and the engine wouldn't at first start. This seemed to be an electrical fault perhaps to a sensor? It did finally start on both occasions, but the rev counter was slow to "fire up". Any ideas?

I'll keep it under observation, but today was the longest runs it has been out and up to 70mph. I also noticed that the alarm on the key sensor was slow to activate, and maybe this is/was the intermittent problem?

Hello Arthur,

I had a problem like this with my 160; it caught me out on a parade lap of Goodwood.

When you turn the key to the first click, listen for the fuel pump. If you can't hear it buzz then the problem might be that the fuel pump relay is on the blink. A replacement can be found on eBay.

hope that this helps

And sometimes you need to hold the security tab up to the key barrel to make it register.

Yes I do this all of the time each start. It is the intermittent bit that gets me though, always the worst. Mustn't jump to conclusions too early, must clearly be a simple electrical fault as gauges do fire up eventually, but as you've mentioned, when it doesn't immediately fire and hold, could be the fuel pump relay. Got to look for that now!
