Riddle me this! 1993 VP series II 3.8L Calais won't start.

Battery is fine.
Plenty of fuel.
Tryed to get it running last night (Jump starting, then called RACV - load of good that did)
would not start no matter what.

Woke up this morning jumped in the car and it started straight away, drove home, parked in driveway, turned off.

Tried to turn straight back on but wont kick.
It turns over but won't actually start.

Any Ideas?

Last night I thought it might be sediment in the injectors but today the car ran smooth as.

So I'm thinking maybe faulty overheating switch or something?

Now I'm thinking Fuel injector module is playing up and either;
A - Flooding the engine or
B - Telling the engine it's flooded?

Let me know what you guys think.

Try pour a cold bucket of water over the crank angle sensor when it won't start next.

I got told to do this to mine because I have trouble starting mine when the engine gets warm and has been sitting for a while.
Didn't work for me but might work for you, give it a try.

If it works, problem = crank angle sensor.

Might try later.

Sorted!

Immobilizer was playing up!
Can't believe I didn't think of trying that!

Ah, glad you got it sorted
