TVR 1985 280I

[Stock 333]

Car starts up fine. after a few minutes the idle will drop down and the car will stall out. If I try to restart it only the engine will turn but not fire up. If i want about 3 to 4 minutes it will restart just fine again.

Any idea why its stalling out and will not restart right away.

Thanks

Fuel pressure maybe?

Fuel pump overheating perhaps?

This is an old thread which might be of use

the main question here is: when did this problem start? out of a sudden or did you or somebody else some work on the car?
or was it into storage over winter etc....

could be fuel-pump related, fuel-pump relais related or lots of other things....

You might benefit from checking the supply voltage at the ignition coil before and after it stalls before getting in deeper

The coil supply voltage can only be measured correctly by having the coil load on/in the circuit

A bad supply or a supply through a ballast resistor will still measure as 12 volt when the coil load isn't on/in the circuit

You need to remove all cables from the ignition coil negative terminal

Use a jump lead to connect the coil negative to battery negative or a known good earth

Now switch the ignition on and measure the voltage at the coil positive

Don't leave the ignition on for too long as the coil could overheat, 10 to 15 seconds isn't a problem

You will have then measured the supply voltage to the coil while it is under coil load (coil is drawing current)

my 1986 280i wasn’t running when i brought it years back and it would start and run but needed the revs high and foot on the pedal, or it would eventually stall , especially when It warmed up ,
turned out the rubber vacuum tube had perished and it was air leak causing problems, i’m probably wrong but worth a look

Try another ignition module if you can get/borrow one.

thats a good advise!!! i would remove this hose and bent it reverse...so you can see if the rubber is cracked on the interal-side of the 90degee ellbow....as far as i know this hose cannot be supplied anymore by Ford...but its quite easy to replace it by some aftermarket silicone-hoses

Thanks for your suggestion. I had several replies and tried trouble shooting all of them. Got your suggestion after I was frustrated and decided to bring it into my mechanic without looking at what you said could be the problem. Immediately the mechanic looked at the bellows and sure enough that was the problem. He put duct tape on the cut it and the problem was fixed. Not your problem but wish I got your suggestion first as it was the easiest thing to fix.

Thanks
