I have a 97 monte carlo z34 3.4 dohc (POS motor i know) anyways , i was driving down the highway at about 120km/h when a heard a clunk and the engine just died completely and hasnt been able to start since , you can hear the fuel pump prime , and it has brand new fuel system as it was just saftied , oil change was just done , and the car died , now i am stumped , we are tight for cash right now and kind of need this car back up and running , but dont have alot of money (new baby on the way ) to put into this thing to try to find the problem , and sure cant afford a mechanic to look it over (just put 2000$ into it for safety , mechanic did all the work) , so we need to fix the problem right the first time please if you have heard of this before let me know i am stumped.... thanks! (by the way the engine does crank , just will NOT turn over but sounds like it wants to!)(and yes it has gas 1/2 tank to be exact)
