Hi Guys,
wonder if you can help me / give me some advice.
The other day my IS overheated good and proper and following that I now can't get the engine to fire, it will turn over but wont catch and fire.
I assumed I'd probably done any of the following having overheated it, cracked or warped head, done the headgasket,buggered a piston or valve so have checked the following.
No mayonaise in the oil either on the oil cap or the dipstick
What's left of the coolant looks clean i.e.no traces of oil in it
Checked compression on all 4 cylinders, all seem fine with readings of 200psi on each cylinder
Spark plus all firing fine.
I'd assume if i've got compression and spark then it could be a fueling issue e.g.knackered pump, or possibly injector issue? or possibly the cranksahft position sensor?
I guess the question i'm asking is does anyone have any ideas, would the car overheating be enough to bugger the fuel system>?
Cheers,
Will

If the results of your tests are as you say, then the overheating isn't directly the cause of your non running. Won't be the crank sensor either, if you have sparks.
Take the rubber hose of of the fuel pressure regulator, and see if fuel comes from the regulator when the engine is cranked as a first test. If not, pull out the fuel pump relay (orange, under the bulkhead wiring cover on the fusebox side), identify pins 30 and 87 of its socket and link them together with a short piece of wire. Does fuel come from the regulator now? Can you hear the fuel pump running?
