Cold start has always been on the button, however hot start often takes quite a bit of cranking to get it to start.
3 times we have been on long drives, stopped to go and do something and then tried to restart it (less than 30 mins after shutting it off) and it has just cranked and cranked.
The first two times, i called out our breakdown, and they got it running again - there was no conclusive action that made it work. In both cases however they did use some magic spray to get it to catch (and confirm that fuel supply was the issue)
I initially thought it was a fuel supply problem, and when taking the tank out there was loads of "pooh" in it. rust and gasket material.
I replaced the tank and the fuel lines in the engine bay, and things seemed to be better.
In the mean time i rebuilt the carb (as it was dirty, and I wanted to see how it worked...). Put it all back together again, and while the cold idle is a bit low and the hot idle is a tiny bit high, it has all been running ok.
Just been away for the weekend. 3 hour drive home, up some mountains and stuff. GOt back, emptied the van and started it up (about 30 mins after shutting it off). Started after the normal hot starting amount of cranking, then 100m up the road just died.
I left it there, came back here and did some googling, and found all sorts of potential issues - but the one that sounded about right was vapour lock.
Went back to the van and did the following:
- Pulled pipes of either side of the fuel pump - bone dry
- Took the top off the fuel pump - a tiny bit of fuel in there
I then drained a bit of fuel from the tank, and put it into the carb.
When i turned it over, it caught and then died.
When i then tried to start it normally, it worked...
I found a load of threads that talked about vapour lock, but i can't really see a solution other than pulling it apart and trying again. which is not practical.
So my questions for the class are:
- Do you agree that this is the problem?
- Sub question - if not, what do you think it is/what else should I check?
- Sub question - if not, what do you think it is/what else should I check?
- If so, what is the permanent fix?
