904 turbo hot start, top 3 causes?

zardoz · Jun 11th, 2010, 13:32

I have looked on here at the causes for my 1994 turbo 904 wentworth hot start failiure. It seems there are a lot! To try and save a little time, what would people on here say the top 3 causes of hot restart failiure were? It has been happening for the last 5 or 6 weeks. I have already changed the oil/coolant and filters last week. I also checked two of the plugs (the easisest to get to) and they were fine.

So I would be greatfull to get some help on the first 3 things that should be checked. Hopefully it will be one of them and i wont have to go through a long list.

many thanks.

Fuel starvation/evaporation ,usually happens in summer,especially on carbed cars.

Have had this on many cars of differing makes over the years.

I didnt actually remedy it, bus was told to fit a heatguard in the appropriate place.

My top 3 for no HOT start

1. crank position sensor
2. Fuel relay (almost a tie for 1st place)
3. Dizzy cap / rotor arm

A no COLD start should be a little more difficult to tie down, so if all no problems on a cold start, try my top 3 ...

Hope this helps !
