car will not start checked everything

Check the fuel pressure. If you do not have any fuel pressure, check the fuel pump operations. The PGM-FI main relay is known to fail causing intermittent non-starting.

okay, i have fuel so would it still be the main relay?

it has good spark when i turn the key fuel shoots out the fuel rail. Has compression no codes, new spark plugs, will not start on ether.

Sparks, compression and fuel pressure. Try some starting fluid. If it fails to start, check the timing belt for skipped tooth.

" Thirty minutes later started car did a half a turn and car shut off"

"half turn" sounds like the battery, connection, or starter problems.

Later portion of this deals with connections.

Battery can be tested in or out of your rig at a popular auto parts store, you can get it running and over there (with a jump or a "charged battery". this same machine can test your entire charging system to insure your battery is being charged by the alternator if it is not, you will soon be back in the same situation.

sorry about that when i said half a turn i got in it and it started so i put it in gear and drove it went to do a u turn and in the middle of the turn it just shut off no noise or anything. i have spark, i have fuel in it. I tried starting fluid, but it still will not start. checked the relay it is working.

You mentioned compression, was it tested?

By the way, are the sparks bright blue or dull orange?

yeah, got compression and the spark plug are new but in the old plugs the where orange i will check real quick with the new ones and see.

If everything lines up good and the sparks are orane, you have a weak ignition coil that is not providing sparks strong enough to start the engine. A weak ignition coil would also fail when it is hot.

checked the spark that is blue and put a new rotor button in among testing it i sat the plug on top of engine over the hole it came out of and tried to start it and it shot out flame.

Looks like you have an over fueling situation. Maybe the injectors are opening too much and that can be due to a problem with the engine coolant temperature sensor.

Remove all spark plugs and disconnect the PGM-FI main relay. Crank the engine for a few seconds to clear out the cylinders of excessive fuel. Reinstall everything and try starting.
