Hi All,

Went out to the car this morning to come to work, unlocked it with the key fob (Cobra alarm), the dash lit up as normal (Handbrake on light etc), turned the key to start it and it wouldn't start.

It's trying to turn over but not catching (almost like the immobiliser hasn't switched off correctly)

Any suggestions of what I can try to get it started tonight (i've borrowed my OH's MX5 to get to work).

This has been the first sign of any issues and it worked fine on Friday night when I drove home from work.

Id try a new battery for the car first, 5's play up with all sorts of weird electrical problems with a weak battery.

Got it started eventually!

It took a bit of persuading but it started. It did come with a message on a the dash something along the lines of "Trans..." (I didn't quite get it before it went off).

Cars seems to be driving fine etc so hopefully it'll start in the morning.

Which engine M20 12 valve or M50 24 valve?
The latter is prone to flooding especially if moved a short distance the night before as it cokes up and that causes it to flood the next morning.

It sounds like the engine spins over as if there is no compression, to get over it remove the fuel pump fuse and spin the engine over until it starts firing then refit the fuse.

The Trans prog fault is an Auto gearbox fault but it can come up on starting with a flat battery, which may have happened when you kept trying smile

It's the 24v... i think you've summed up what happened exactly.

I moved it a short distance on sat morning which probably didn't help.

If you do have to move it a short distance at least let it run for a few minutes pref five this lets it lean off and burn off the soot
