I firstly would check relay. You can use an ohmmeter to check the resistance of the relay. If you get a reading, it is good, If not it is bad. Than disconnect fuel pump wire harness and do the same.

I wouldn't think catalytic converter, without it giving some indication that it was going bad, but without testing it is hard to say.
When it cranks and won't start, check for battery voltage to the coil on the dark green wire, with key ON. If you have power at the coil, it might be a bad coil. If no power to the coil, it could be a Crank Position Sensor or the Cam Position Sensor inside the distributor. If one of those is bad, it can stop the computer from sending power to the coil.
Good luck.

Just turns off on it's own, Wait 60 sec. restart press pedel it dies.


This engine is electronically controlled so the first thing that must be done here is to have the systems control computer tested for fault codes and then do the proper diagnostics based on those codes.

You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

Engine cranks but won't start


If it is an electrical Fuel Pump, you will hear the pump whirring as soon as you turn the key to "ON". If you can't hear it, the fuel pump is bad. If it is a mechanical fuel pump on the engine, remove the hose that goes into the carburator. And crank the engine. It should pump the gas out without a problem. If it does not, the fuel pump is bad. Also check the relay to the fuel pump and the shutoff valve. It is more likely that it is a relay problem since it hits a bump and goes off then it carries a current again. Probably a bad relay under the hood for the fuel system.
