Urgent Help Required: possible Blown Engine
 

I drive a 1990 Aus-delivered FC turbo. Just put some petrol in it and was leaving petrol station where it kinda jerks and hesitated abit(i was giving it abit of gas) and then let out a huge backfire.... Then engine cut out, managed to get it into a car park. When i turn the ignition it starts and then dies off, can't give it any accel, doesn't work. I thought positivly maybe it just somehow flooded, so cut the fuel pump and cranked it, a heap of oil like smoke comes out (grey in colour not blue). If i try and give it gas when starting(fuel pump connected), it just makes a loud backfire before it dies out. Also no buzzers are going off and no leaks visable under the engine bay.

Been running fine lately till now, recently serviced it with a friend, changed all filters, oil and coolant, sparks and wires. Removed cruise control and half of a/c(didnt do the parts behind the radiator yet). Sorry i'd try and tell more but that's all i can really think of. i towed the car home and its sitting in the driveway, so i can check anything you guys want.

Any help greatly appreciated, this is my daily car and first car(19 years old) so i really need it up and running.

I would Compression Check the Engine.The Compression Check wil ltell you right Off the bat if the Engine has any internal Damage..I know you don't want to hear this,But the engine could have just "let go"..the compression check will Tell you that.. on the internet,go to www.rotaryresurrection.com (Kevin Lander's Site,.he is is a good Guy on forum.).Hit Sec Gen. ..then go into te TECH section..there is a Write-up on How to uses a Regular Piston Engine Compression Tester,to Find out if your Engine is OK....I feel this is the first thing that you should do,seeing that you Already did a tune up,and so forth...If the Compression Check Reads OK,then you can look into other stuff..like Electrical,Fuel,Etc..Good Luck..and watch out For ROOS!..STYX!~

did you somehow reverse your plug wires?

Yeah compression check is on my list. Got a friend coming to check the car out tonight. I was guessing it was gone, so not really hurt hearing it. Just wanna check hear before i go wasting money checking useless b/s. Wires are right way(?) otherwise it would have problems right from go right?

Just wanted to say thanks to everyone! Fixed it and luckily wasn't a blown engine. Started looking through electrical connections and then spotted my cooler hose just sitting out(stock top mount) so there it was, somehow the hose had popped out. Rebuild is going to be high up on my list of things to do now though so i dont have to worry about this again. Previous owner was a numb nut.
