check high tension lead from coil to distributor and distributor rotor voltige or fuel not reach the pistons,notes2000 rpm you have this stop the car engine on rev 2000 rpm and spray your filter with engine start same time exalaraite to high revs and se the risults.good luck.

1st run scans for fault codes.

If the engine does not reach 300 rpm while cranking..engine will not start.

It needs good battery power to crank these with spare power to run the electronics.

If with good battery if fires and immediately stops, and the little 'yellow car' is illuminated in the cluster.... the immobiliser is active and you need a shop to fix it.

BTW..Stop with the Easy Start fluid already. You'll break a piston ring or worse...such as....the Glow Plugs will cause a back fire and you will likely strip the timing belt...major repairs...like $3500 and up.

If you broke a timing belt while it was running you bent valves and the heads need to be worked on.You probably have a cylinder with no compresion and the computer is sensing it.

Vacuum leaks. Check all hoses and intake bolts. Leaking EGR or plugged PCV valve. Air filter plugged. Leaking head gasket. Worn timing chain. Camshaft lobes worn. Valves burned or leaking. Fuel idle control system or sensor. Good luck!

Sounds like the timing belt tensioner. I have that problem. Rattles at low rpm, goes away as you acceralerate. Looking to have timing belts changed and tensioners replaced.
