I have made some progress with this car but still not right. Orginally, it was not getting any fuel to the distribution but now it does. The car starts up and then quickly dies. It will however, run a bit longer with a plug out..It doesn't matter which plug as long as one is out. Just kinda depends on its mood. I have checked and/or changed the following; plugs (bosch), plug wires, cap and button, fuel pump, fuel filter, idle control valve is working, battery is new. I have check fuel pump flow (one liter in under 40 seconds). Fuel pump relay is good. OVC is good. Fuel lines are good and clear (even frame lines). O-ring under FD is new. Vacuum lines are ok..Tank was flushed. Timing seemed to be ok. I have also tried adjusting the lamda tower screw and it doesn't matter. The car reacts the same..

I've tried and tested just about everything that I could think of. Now I'm out of ideas. Where should I be looking now? Ignition module? Any ideas are welcome..!!!

I still think it is likely you are getting too much fuel, which is why it will run a with a plug out....

I still think you should try introducing a vacuum leak by disconnecting a hose or two.... See if you can make it run my manually leaning it out this way.

If so, it could be leaky injectors, or somebody screwed up adjustments trying to get it run before you got it.

Try replacing the crank position sensor.

tried pulling a vacuum line off it didn't seem to change things..I wonder does anyone know how to check ignition module.. and the crank sensor.(thanks randy)?

Hi Brent,

I didn't mention anything about the CPS or IGM because you stated that the engine would run if you put gas in the intake, and now it even runs with one plug out.

Anyway, here a link that discusses Crankshaft Position Sensor testing.

thanks for the link Dave...hope your trip went well..

The reason I'm shifting my thought to ignition (other than just tired of smelling like gas..ha ha) is because we have went complete through the fuel system and so has the previous owner. Maybe it's not the problem anymore. we have corrected quite a bit but just seems to still missing something. As I type this, wonder if the cat might stopped up. that would kinda make sense. I haven't checked it. That might explain why it tries to run a little with the plug out. Its not build that much pressure.Hummm whatcha think about that..???
