any help is appreciated, will start by uncliiping the dist cap and rotating counter clock wise. Timing verified and ok, battery voltage ok, compression is 90 , 85, 75 ,80 on cold test. sPARK OK, INJECTION OK, RUNS FANTASTIC WHEN ON..........................Any idea"s?

Do you mean "unclipping the dist cap" or loosening the hold down bolt?
Unclipping the distributer and moving it while the engine is moving is not wise.
edit: Motronic timing is not adjustible, maybe you mixed up your wires?

No start

i realize it is not wise, unfortunatley the only way to get it started at this point, wires are not mixed up, when car is on it runs great!

Are the compression numbers in PSI? If so that seems low. Was it tested with the throttle propped wide open? (it should be)

If truely low that could explain difficult starting.

Make sure the cam timing is OK and the valve clearances are OK. And that the valves are sealing OK. If any of those are off then intake vacuum could suffer making starting difficult. And if compression is that low then power must be down, too.

Try a second compression test (good battery, throttle wide open) after putting about 20-30ml of engine oil into the cylinder. If the compression comes up a lot then the rings may not be sealing well.

Can you arrange a leak down test?

i put oil and no diference in compression .timming ok i did a leak down test result cyl 1 10% cyl 2 20% cyl 3 40% cyl 4 35% with engine cold

Were you able to determine where the pressure loss was occuring - especially in #3 & #4? 10%-20% is liveable but 35%-40% is quite high. Little change with oil added to the cylinder would indicate the valves are not sealing well. Poorly sealing valves (especially intake valves) can cause difficulty starting. Once started, it can run OK.
