Not starting (again.......)

[geordieggg]

Seems like this was my last post as well, but I got the last problem sorted eventually.........:stupid:

Here's the story so far:

Car is a GS31 that's had the original L20A removed and replaced with an L28 by PO, whoever did the swap left all the L20 EFI gear (manifolds, ECU, AFM etc) there and hooked it up to the L28. Car ran fine when I first got it, started first go.

Since putting the motor back together and doing a few laps at Teretonga (a local race track), I've had the car out a couple of times, without any major problems. She seemed to run a little rich on cold starts (a bit smokey when revved but it cleared as it warmed up) and drove fine.

On Saturday, drove it around town a little bit, bought it out home and parked it in the hay shed. Saturday night, had to move it out, started fine. Did what we had to do in the shed, so I started it back up, moved it inside and parked it in the middle of the shed.

Sunday, had to move it from where it was, wouldn't start. Cranked a coupe of times and coughed. Did this three times, then just plain wouldn't start and hasn't since.

I've checked, it's got spark, air and fuel. Nothing has changed on the car since parking it Saturday night and trying to start it Sunday morning, so it's got me stumped! Now when I try to start it, it smells like it's flooding, so I checked the coolant temp sender and the thermotime switch, both check out ok (checked the coolant one through the harness at the ECU, and was still fine).

What else could it possibly be? Is it possible for the cold start valves to stick open? I know the thermotime switch should only allow the cold start valve to open for a set amount of time, should I just remove the cold start valve and see what happens when cranking?
