My car would crank but not start. I took it to two repair centres and they checked it. 1 said the oil leak caused the crank shaft sensor to go bad and that is causing the problem. the other said the oil leak is a problem and the EGR valve and air mass meter boot are giving error codes. I got the oil leak fixed. Car started, got it back but now after a week the same thing happens, cranks but will not start

What should I do? Replacing the EGR valve is expensive..Crank shaft sensor does not give an error code.

I'm a student and do not have a job. I need help !

No start do below:

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor camshaft and crankshaft sensors- Note: If it doesn't apply disregard it
