Hot start, well may be?

[kelvinwannell]

Please can one of you more iteligent guys help me, I do know if I have the hot start issue or not. I am unable to find a third relay.

Chim 4.0 1995, starts straight away, run it for 30 seconds, turn it off it will not start again. Fuel pump running ok, starter turning ok, but car will not restart until cold. It does try a tiny bit, the odd fire, but very little, not enough to start.

Any help would be greatly appreciated. Keep up the good work and thanks in advance.

It does turn over ok, fuel pump running ok (3 secs) engine try's to start, but just the odd fire, just sounds very weak.

It has new coil (correct one) new alternator, new little black box thing on heat sink, new leads and dizzy cap, new plugs.

Can't get my head round it.

This morning started straight up ok, turned off after about 30 secs, would not restart.

Thanks guys, will make some checks, as suggested.

Thanks for your help so far.

I start it up for a min or so, try's to start but will not, does sound like it is firing a bit.

I have a good spark, I have plugs sparking, it seems like a fuel issue, but, the fuel pump fires up for the 3 secs and works fine until the car is turned off, it is then that it will not start again, fuel pump does the normal 3 secs, so I do not think this is the problem. My only thought is the computer getting wrong information from a sensor and limiting the fuel, is that poss?

aany help is always appreciated.

Thanks for the reply's.

I don't think it's the fuel pressure regulator, it starts and runs when cold, the regulator would not work when cold, if it was that.

I also have installed a new temp gauge.

The only other thing I have found, when I start it cold and leave it running, it starts to miss and will eventually stop, then not restart.

Anyone near Horsham got a Rover gauge? Would that help?

rgards all.

Have now tested the temp sensors, they do read a little different. Can anyone tell me what the correct reading should be, on my multimeter?

Also, what should the fueld rail pressure be when running?

Thanks for your help guys.

[kelvinwannell]

I have already installed a new one, the values are the same as the old one, so should be ok.

thanks for the reply.
