Hi there, I'm new to this forum but have read a great deal of threads recently. I have a 1997 R reg 1.6 SX Auto Bravo. I have done a huge amount of work on it including a new head gasket, cambelt, filters, plugs, etc.
After all this when the engine was back together it fired up well, and revved nicely. However, it has been left standing for a while (5 months?) and now fails to start up. The starter turns, the fuel pump primes, there is pressure in the fuel pipe, there are sparks 'cos it tries really hard to fire. It might just catch for a few seconds rev and then die. It is almost as if it isnt getting enough fuel, or air?
The throttle appears to open OK, I have had the air filter pipes off. Sometimes, when trying to get it to catch the engine seems to backfire or pop. I dont think it is the timing as when it does fire it is smooth, but that doesnt last!!
Pumping the throttle seems to make it worse, in fact touching it at all during the process is a no-no.
If it is left for a while it tries again, but subsequent tries get worse until the battery starts to complain.
Also, the ECU has been "doctored" to turn off the immobiliser, 'cos I had problems with that a while ago - but I know that all works 'cos is was fine earlier this year.
I am at a loss as to what to look for now, and thought I would ask you guys....this is before I do a real Basil Fawlty on it.
Thanks...
