We will have to pinpoint what the engine is missing.
- Spark
- Fuel
- Compression
All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.
Thereis a relay in the Power Distribution Box, that governs the fuel pump (click image for zoom)...
Test it and keep us updated.
This is the type of problem that calls for advanced troubleshooting. I see people giving out advice all the time based on past job they have done or "what could be wrong". I don't like running people in all different directions. This problem could be:
The list goes on and on. A good mechanic will look listen and study the problem throughly. This takes time and patience. If there is only one cylinder misfiring then this is where the attention should be given, to the bad cylinder. If it is a intermittent problem then calls for other strategies. A vacuum leak
A valve issue
Timing Chain
Ignition
Exhaust Restriction
Fuel Pressure
